Aircraft Fuel Tank Safety & Maintenance � Part I

Aircraft service and maintenance are important functions to ensure safety of flight.After all,you do not want to have a maintenance issue while you are in flight.Every precaution must be taken while the aircraft is on the ground so that you arrive at your destination without incident.



Proper inspection should include a thorough investigation of the aircraft.In particular,the interior of an aircraft fuel tank requires intense scrutiny and attention to detail.The fuel tanks must be checked for multiple discrepancies to include:

• Fuel leakage

• Fuel quantity probe replacement

• Fuel boost pump obstructions

• Faulty wiring

• F.O.D.

• Structural damage to wings (cracks and corrosion)

• Sealant deterioration



To properly perform aircraft fuel tank inspections and maintenance,technicians must physically crawl inside of the fuel tank if accessible.Most aircraft fuel tanks are not large enough for an average sized man to maneuver within easily.For example,the largest fuel tank of a DC-9 measures approximately 2-1/2 feet high,4-1/2 feet wide and 4-1/2 feet long and are usually smaller on many corporate aircraft.



Due to the hazards of working in such confined spaces,OSHA regulations are in place to protect technicians that are required to perform aircraft fuel tank repair as part of their daily duties.



Additionally,maintenance technicians face multiple dangers while performing aircraft fuel systems inspections and repairs. Furthermore,jet fuel and other chemicals used internally within the fuel tanks may also contain toxins or irritants that can have adverse affects to the central nervous system.



To protect technicians from these types of hazards,specialized training and procedures are in place.



Training.Before a maintenance technician can safely enter an aircraft fuel tank, several critical steps included below must be performed:



• Electrically ground and defuel the aircraft

• Gather and stand by with properly functioning fire protection equipment

• Deactivate associated aircraft systems as required

• Ensure proper ventilation, by applying the proven recommended ventilation techniques

• Frequently monitoring the air quality within the aircraft fuel tanks



Portable gas detectors are used to monitor the oxygen and flammable vapor concentrations within the fuel tanks.Oxygen concentrations should be between 19.5 and 23.5 percent.Levels below 19.5 percent are considered oxygen deficient,while levels above 23.5 percent will significantly increase the risk of fire and/or explosion. Monitoring these numbers is critical to the safety of the maintenance crew.



Proper training of the maintenance crew is an important component to conducting proper aircraft fuel tank repairs without an incident.These technicians must maintain constant and accurate voice communication and continuously monitor the aircraft fuel tanks and their surroundings’.All technicians must understand the many critical components within the aircraft fuel tanks,to prevent injury to personnel and costly damage to the aircraft.



Emergency Response Plan.



The unfortunate reality of aircraft fuel systems maintenance is that potentially severe issues can occur.The interior of a fuel tank can be a particularly hazardous environment. Therefore,all aircraft service and maintenance procedures should also include an emergency response plan. Appropriate training is critical to ensuring the safety of flight.Aircraft fuel systems maintenance is an intricate procedure and requires significant monitoring to ensure the safety of all involved.Proper training and effective processes will support a healthy work environment for fuel tank repair technicians by recognizing hazards and having proper protocols in place to respond to any issues that may arise.

How to select an HVAC School

What could individuals residing in Chicago, IL manage to do without having home heating, individuals in Las vegas work without air-conditioning, or perhaps hospitals all over the country achieve with no refrigeration? Not really a good deal.

Heating and Air Conditioning And HVAC Education Career Outlook

So , unsurprisingly, employment candidates for heating and air-conditioning technicians as well as installers are anticipated to remain superb, particularly for the people who have specialised institution and / or official instructional coaching.

Due to the fact heating and air conditioning generally come about on the same techniques, the field is commonly lessened into the abbreviation HVAC. And since the economy progressively needs heating and cooling, Heating and cooling educationwell worth thinking about.

Heating and cooling systems contain quite a few electro-mechanical, electrical, and electrical equipment, such as electric motors, compressors, pumps, oscillating fans, ducts, piping, thermostats, as well as fuses. In the central heating systems, for instance, a furnace warms air this is distributed through the entire property via the method from steel or fiberglass tubes.

Heating and air conditioning techs have to be capable of maintaining, diagnose, and correct difficulties all over the entire system.

Due to the growing sophistication associated with Heating and cooling products, organizations choose to retain the services of people that have Hvac education. Many mechanics and installers, however, still learn the industry informally at work.

Heating and Air Conditioning / HVAC Training

Numerous HVAC schools offer Six month to 2-year Heating and air conditioning schooling programs. Trainees analyze principles, design, and machine design, and also electronics. Additionally they learn the essence of installing, maintenance, as well as repair service. Sensible Heating and cooling instruction courses usually provide curriculums on HVAC math, mechanical designing, applied physics as well as chemistry, circuitry, blueprint understanding, also computer systems.

Technicians may work for small or large contracting providers and / or exclusively for almost any producer or middleman. Those employed by smaller-sized companies tend to undertake both the installations and even maintaining, along with work with home heating, cooling, plus refrigeration equipment. Service contracts-which involve heating system, and air conditioning pertaining to explicit consumers for a regular basis-are starting to be general. Service contracts assist in reducing the seasonal variations of this work.

Prior to selecting a good HVAC school, it is vital that a school you select is licensed. Only approved HVAC educational facilities present the degree of schooling that is congruent along with the actual principles collection forth via these numerous Hvac accredidation organizations. Credential by a particular accredited program is definitely a prerequisite intended for those Hvac School graduates who favor that will pursue HVAC certification later on on. Currently, there are only 3 accredidation bureaus for HVAC Training: HVAC Excellence, The National Center for Construction Education and Research, and the Partnership for Air-Conditioning , Heating, and Refrigeration.

Ball Joints and Your Car's Suspension System

An important part of your car's suspension system is its ball joints. Made of extra tough steel, ball joints act as the pivot point between two parts: the suspension and your car's tires. Ball joints help support your car's weight and, as is the case with some vehicles, ball joints may be used to help set the alignment. Let's take a closer look at this key component of your car's suspension system.

Enclosed in a steel housing, ball joints are used on the front end of almost every car, truck, SUV, and minivan. As might be expected, ball joints are subject to a lot of wear and tear, so to properly protect them ball joints are housed in an enclosed boot to keep dirt away from the joint assembly.

There are two types of suspension systems that use ball joints. The first is a conventional system that uses an upper and lower ball joint. The second is called a MacPherson strut system that uses a single lower ball joint and an upper strut bearing. No upper ball joint is needed as the upper strut bearing does the job instead.

Maintenance for ball joints has changed over the years for most cars. Many vehicles come equipped with ball joints that are permanently lubed, so lubrication is not necessary nor is it even possible as the pack that holds the lubrication is permanently sealed. When ball joints wear out or are damaged, you can find replacement ball joints that come with lubrication fittings; in this case you would need to lubricate your ball joints on a regular basis as in when you change your vehicle's oil.

When performing an inspection of your car's suspension, your ball joints should be looked at too. Have a complete wheel alignment performed and make certain that the ball joints are not worn. If the ball joints wear out and are not changed, you will soon experience uneven tire wear or unreliable steering, such as wandering. Clearly, worn out ball joints are a safety issue that must be tended to and fixed immediately.

Ball joints are developed for the specific make/model of your vehicle. Many models share the same suspension system as other models within the brand, but to be sure check your vehicle's repair manual for the right replacement ball joints. Certain manufacturers, such as Moog, develop ball joints for many makes/models and can be used by mechanics that prefer this particular product. Check online to find out more information about Moog ball joints and whether they are right for your car.

Remember: ball joints are an important part of your vehicle's suspension system. Annual check ups of the suspension can head off costly problems which can also impact your safety.

The Jones Act – Maintenance & Cure

The Merchant Marine Act of 1920 is one of three congressional laws commonly referred to as the "Jones Act". Formerly, it was found at 46 U.S.C. Section 688, et seq. and was recently codified in October, 2006 at 46 U.S.C. Section 30104 et seq. The purpose of the Jones Act was to recognize the importance of a strong merchant marine system for national defense, and the growth of foreign and domestic commerce by protecting the mariner. Dating back for many centuries, the shipping industry has long been accepted as vital to the economic existence of countries. It was always important that when a seaman was injured far from home, it was the duty of the ship owner to repatriate the injured worker.
The Jones Act is one of the few areas of the law that is still favorable to an injured worker. It applies to deck hands, engineers, third mates, second mates, first mates, relief captains, captains, roustabouts, roughnecks, drillers, pilots, tanker man, anchor tenders and basically all persons that are involved in the maritime offshore industry. It applies to the fishing, fishery, canning, shrimping, oil field, dredging, barge, tugboat, towboat, crew boat, supply boat and other maritime offshore industries. The Jones Act was enacted after FELA but adopts FELA's liberal construction in favor of the injured worker.
The Jones Act applies when: A seaman, while working on board a vessel, is injured in the course and scope of employment upon a navigable waterway. Though the previous sentence would seem easy to apply to determine the applicability of the Jones Act, unfortunately this is not the case even after almost a century of American jurisprudence.
Who Is a "Seaman"?

United States' courts have struggled with "Who is a seaman?" The various federal circuit courts seem to agree that, to qualify as a "seaman", the person has to be permanently assigned to an identifiable fleet of vessels. For instance, a diesel mechanic that works for ABC Co. who is sent to repair the engines of a vessel that is owned by 123 Company would not be covered by the Jones Act if he injures himself on that vessel. This is because he is not "assigned" to that particular fleet of vessels and is, therefore not a "seaman". Even a Pilot, whose sole job is to get on and off ships and navigate them into a harbor day and night are not covered. This Pilot example demonstrates that a person, whose work is 100% on the water and constantly subject to the perils of the sea, may still not qualify as a "seaman". Each situation must be determined on its own facts.

What is a "Vessel"?
Even though maritime law is the oldest law in the United States, the courts still wrestle with what is a "vessel". The obvious vessels such as a barge, dredge, jack-up barge, drill ship, work over rig, floater, platform, crew boat, supply boat have always been considered vessels. As examples, (1) with the continual development of new technologies to seek and extract oil and gas from the seabed floors, the courts have been faced with determining whether new types of devices are vessels for the application of the Jones Act; these include Tension Leg Platforms (TLPs or TWLPS) which do not stand upright when released from the seabed floor; or (2) a casino that is otherwise a riverboat that floats perfectly, but, because it never moves and is permanently tied to the shore, it has been held not to be a "vessel". In a recent U.S. Supreme Court opinion, the Court attempted to finally define what a "vessel" is. In Stewart v. Dutra, 543 U.S. 481 (2005), the Court proclaimed that a vessel is "...a watercraft that is used, or capable of being used, as a means of transportation on water." This definition seems clear enough but it remains to see, as technology advances, if the "murky waters" of maritime jurisprudence still are not sometimes challenged in the legal classification of what is a "vessel".

Where are "Navigable Waterways"?
When the Jones Act became law, the merchant marine industry started to grow. It was, in fact, this industry that was extremely helpful in WWII in assisting the Navy. However, approximately in the late 1970s, the fleets and numbers of ocean going U.S. flagged vessels began to shrink and were replaced by an increase in foreign flagged and foreign owned vessels manned by non-U.S. citizens. This is a tragedy but a historic reality. This type of vessel is commonly called a "blue water" vessel. Today, there are only a handful of American flagged "blue water" vessels. However, with the increase of offshore drilling, the "brown water" vessels became abundant. Obviously, the Atlantic Ocean, Pacific Ocean and the Gulf of Mexico are navigable waterways. However, there has always been, and will always be, a healthy barge traffic business in America's heartland. This inland waterway system, including the mighty Mississippi River and its tributaries, are also considered navigable waterways for purposes of applying the Jones Act
Maintenance & Cure is Owed Without Regard to Fault
An injured seaman is entitled to maintenance. Maintenance is that some of money that would be required to supply room and board similar to what was supplied to the seaman on board the vessel. The maintenance is very low and is a per day payment. It is sometimes as low as $8.00 a day and sometimes as high as $35.00 a day.
An injured seaman is entitled to cure. Cure has been defined as reasonable and necessary medical care to return the seaman to a point of maximum medical improvement. Though these payments should be automatic, often times the seaman is faced with an employer that does not fulfill its obligations to give medical care and, unlike state workers' compensation schemes, there is no statutory obligation to compel the employer to provide medical care.
Both with maintenance and cure, often times the employer, though obligated, simply does not pay what it should or, sometimes, does not pay at all and the Jones Act provides a useful tool to get the seaman compensation. Maintenance and cure are actually rights that a seaman has had for hundreds of years and, unlike the Jones Act, are not governed by fault. In other words, even if the seaman is 100% at fault for his/her injuries, the duty of the employer remains the same.

An Injured Seaman Is Not Covered By Workers' Compensation and the
Jones Act is a Fault Based system

Before the Jones Act was enacted there was no remedy against an employer for an injured seaman other than maintenance and cure. However, the Jones Act is quite different from workers' compensation statutes. Assume for the moment that you work at McDonalds; that you are mopping the floor and that you slip and fall in the soapy water that you put down and hurt your back. If this happened to you, you would be entitled to (1) your medical care for your injuries; (2) two-thirds of your average weekly wage while you are being treated; and (3) maybe a relatively small monetary settlement. But what if you could never return to medium or heavy type work again? Obviously, you would lose much money over the course of your work life. Also, and most importantly, note that you get these workers' compensation benefits regardless of whether you were actually 100% at fault in causing your fall. This is where the Jones Act is quite different. Under the Jones Act, if you are hurt while working as a seaman on a vessel, you are entitled to nothing unless you prove that your injury was caused by the negligence (failure to act with reasonable ordinary care) of someone else or from an unseaworthy condition. "Unseaworthy" or "unseaworthiness" is defined as something on the vessel that is "not fit for its intended purpose" such as a rotted rope that breaks or a ladder that gives way. Unlike workers' compensation, if you are held to be 100% at fault, under the Jones Act you get nothing! But unlike the hypothetical McDonald's employee, you have the right to sue the employer and you can choose to sue in either a state court or a federal court. If you are successful, you can recover compensation for pain and suffering, mental anguish, physical impairment, physical disfigurement, loss of wages in the past, and loss of future earning capacity, vocational rehabilitation damages and other types of damages. The hypothetical McDonald's employee cannot sue his employer if he receives workers' compensation. Thus, the Jones Act can be much better for the injured worker but can also be worse if the injured employee does not prove his case adequately.
"Comparative Negligence" Under Jones Act
Another concept to understand about Jones Act is that it applies the legal doctrine of "comparative negligence" to all Jones Act claims. Under a "comparative negligence" approach, the jury hears testimony about the negligent conduct of both parties--the employer and the maritime worker. Based on the evidence, the jury will determine what the injured party's damages are and how much should be allocated to each party. Sometimes accidents happen not just from the employers' negligence but also from the worker's too. The good thing about "comparative negligence" is, even though the jury may find a percentage of negligence on the worker, the injured worker still recovers the percentage of the jury's monetary award that is equal to the employers' percentage of negligence. By way of example only, if the worker is found 25% negligent and the employer is found 75% negligent and the jury awards $875,000.00, then the judgment would be that the worker recovers $656,250.00 plus costs. This is quite different than in almost all states where, if the injured person is found 51% or more negligent by the jury, the injured person would recover zero no matter how much the jury awarded for money damages.
A Jones Act lawsuit must be filed within three (3) years of the injury date or it is barred by the Statute of Limitations.

Arai Motorcycle Helmets

There are some great helmets on the market and that includes Arai motorcycle helmets with its world wide reputation. In fact once again Arai has scored #1 in the JD Power and Associates Motorcycle Helmet satisfaction studies. That's 6 years running - pretty impressive!

And of course for that quality and the number one helmet on the market you have to be prepared to spend a little more. All those Arai fans wouldn't have it any other way. But for the price a little bit of scrutiny is certainly in order.

There are other helmets that would be comparative to the Arai including the Shark RSR, Scorpion EX-700, or the Shoei RF-1000 all of which are plush and comfortable, and they are priced well. In fact they cost about one-third of the price of the Arai Quantum II.

Arai has three different shells - the round oval, long oval, and earth. They've also recently added the intermediate oval. Arai is the only manufacturer that offers more than one helmet shape and they should be recognized for it! A premium price is worth it for a premium fit. After all your helmet should fit like a glove shouldn't it?

The Quantum II does just that with its earth shape and sizing up to XL. The earth shape has been extremely popular with those that have an earth shaped head. Arai staff are trained to fit your Arai helmet to your head so stop by one of their dealers.

The Arai has great air flow through the chin vent which spills out onto your face. On some helmets it is directed to the back of the head. The front flow is great during the summer months but be warned if you spend much time on your motorcycle during the colder seasons this air can be real cold!

The biggest complaint it that the top vents have tiny rocker switches that open and close and during the colder months when wearing gloves you simply can't feel these little paddles. Gloves make the horizontal strips hard to maneuver too. Winter issues only.

The other draw back is the way the visor is removed. It's a poor system and not nearly as effective as the Shoei release. It's clumsy and has the extra pod to mess with. And it sounds awful when you remove it. But once you get use to it, it's okay.

As you can see the cons are really minimal. The Arai helmets are nice looking, reliable, well built, and they fit terrific. This makes them a great choice. But be prepared to dish out at least $600 and you might want to shop around a bit because there are other brands like Shoei which are available online at a much better price and yet they offer a comparable helmet.

Arai helmets are available only through their dealers and they are not allowed to move their products via the internet. This means they can better keep their prices on the high end.

Arai has a record for consistently providing the best in helmet comfort, quality, and safety and they have been doing that for more than 20 years. And safety is what it's all about right?

So if you are in the market for a new helmet consider an Arai motorcycle helmet but have a look at what else is available online. Then choose what's best for you.

Brake Rotors - Check Them And Replace Them In Time


When you sit on the driver's seat and turn the ignition key you hear and feel the engine come to life. If this is an old car you will be familiar with the reassuring purring sound of the car's engine and you will know that all is well with the engine of your car and soon you will be on the way. If there is anything amiss you may spot it in the sound of the car's engine. But not all components are so easy to check, howsoever broadly. There are components that are quite passive until called into action and unless their performance breaks down completely you may not become aware that they need to be paid some attention.

For such components you need to inform yourself better about how your car works and once you know that they are a key component you can ask your mechanic to inform you the status each time the car goes for a service and if it is time to replace them you can make sure you get them replaced by a high quality option.

One such component are the brake rotors. They are the component that brake pads rub against and create the frictional force that helps slow down or stop your car. Now it is more widely known that brake pads get worn out and need to be replaced, but over a long period of time the brake rotors themselves may need to be replaced. So if you feel the braking system of your car is no longer what it was you should get the brake rotors checked along with the brake pads.

And if it is found that you need to have them replaced you should look for the latest options and choose the best one for your car. You have a choice of the regular drilled brake rotors and the high performance slotted brake rotors. The holes and slots help dissipate the heat generated due to the friction. Slotted brake rotors are better suited for high performance applications and wear out the brake pads faster. For regular use drilled rotors are good. You can see the latest brake rotors at www.ilovebodykits.com.

The Exhaust System

Your car's exhaust system carries away the gases created when the fuel and air are burned in the combustion chamber. These gases are harmful to humans and our environment. A frequent check of your exhaust system is a must to provide for you and your family's safety. Make sure there are no holes in the exhaust system or in the passenger compartment where exhaust fumes could enter. Let's begin by listing the parts of the exhaust system and their functions.

Exhaust manifold: The exhaust manifold attaches to the cylinder head and takes each cylinders exhaust and combines it into one pipe. The manifold can be made of steel, aluminum, stainless steel, or more commonly cast iron.

Oxygen sensor: All modern fuel injected cars utilize an oxygen sensor to measure how much oxygen is present in the exhaust. From this the computer can add or subtract fuel to obtain the correct mixture for maximum fuel economy. The oxygen sensor is mounted in the exhaust manifold or close to it in the exhaust pipe.

Catalytic converter: This muffler like part converts harmful carbon monoxide and hydrocarbons to water vapor and carbon dioxide. Some converters also reduce harmful nitrogen oxides. The converter is mounted between the exhaust manifold and the muffler.

Muffler: The muffler serves to quiet the exhaust down to acceptable levels. Remember that the combustion process is a series of explosions that create allot of noise. Most mufflers use baffles to bounce the exhaust around dissipating the energy and quieting the noise. Some mufflers also use fiberglass packing, which absorbs the sound energy as the gases flow through.

Exhaust pipe: Between all of the above mention parts is the exhaust pipe which carries the gas through it's journey out your tail pipe. Exhaust tubing is usually made of steel but can be stainless steel (which lasts longer due to it's corrosion resistance) or aluminized steel tubing. Aluminized steel has better corrosion resistance than plain steel but not better than stainless steel. It is however cheaper than stainless steel.

Common Problems:

Well the worst enemy of your exhaust system is corrosion.... or more commonly known as rust. Rust is caused by moisture reacting with the iron in the steel and forming iron oxide. Moisture, or water vapor is present in the exhaust as a by-product of combustion and the catalytic converter. Moisture can also come from the outside in the form of rain.

Short trips in your car can shorten the life of your exhaust system. When you shut down your engine whatever water vapor is in the pipes condenses and turns back into a liquid. On a short trip the water never has a chance to get hot enough to turn back into water vapor and just stays in the system and rusts away the pipes. If you drive for short distances consider replacing your exhaust system with stainless steel when the plain steel one rusts through. If you drive more than 15 miles at a time then you should not have to worry about this.

If you live in an area, which uses salt on the roads in the wintertime, make sure to wash the underside of you car with water every few weeks. Salt speeds up the corrosion process and getting it off as soon as possible will help stop the corrosion. Make sure you run the engine after washing to drive off all of the water on the pipes.

Noticing a decrease in your gas mileage? Your oxygen sensor could be going south on you. As time goes on the oxygen sensor begins to wear out and becomes less accurate. This sometimes results in a rich fuel mixture where your engine burns more fuel than is needed. Most of the time your check engine light will come on and alert you to a failing oxygen sensor. I suggest changing the oxygen sensor every 60,000 miles just to be safe. Even though your check engine light might not be on, you could be using more gas than is needed. Pay a few bucks and change the sensor, your wallet will thank you when you have to buy less gas down the road.

The next part in line to go is the muffler. Most of the time mufflers rust through and need to be replaced. There are allot of options out there for replacement mufflers. Some cheap and some expensive. It holds true... you get what you pay for. If you plan on keeping your car for any period of time, spend the extra cash and get an OEM muffler or a high quality name brand muffler.

On rare occasions the catalytic converter will become clogged and need to be replaced. Symptoms include loss of power, heat coming from the floor of your car, glowing red converter or a sulfur smell. Never let a mechanic tell you that you can do without the catalytic converter. Removing this component is illegal in most states and can lead to a hefty fine to the government if you are not careful.

That's about it for the exhaust system; just remember that rust is the biggest enemy to your exhaust system. Take the above-mentioned steps and your exhaust system will last a long time

Automotive Air Conditioner Basic Troubleshooting Tips

If your automotive air conditioner isn’t working quite right, here are a few ideas to begin. First of all start with the control panel on your dashboard. Most automobiles have an A/C button that actually turns the compressor on and allows cold air to be circulated. You might have accidentally hit the recirculation button instead of the A/C button. (Don’t laugh, I had a friend that spent a week in a hot car and all he needed to do was press the right button.) The second thing to check is the actual function of the controls. Do they move at all? Are they loose and giggle around? The big question is “do they feel different from the last time your air conditioner worked?” This could tell if the controls are messed up and need replacing. Your air conditioner system may be fine but the controls could be frozen or broken. If your controls seem to be functioning, lets move to the blower fan. Turn on your car and start you’re air conditioner as you normally would. Then turn your blower to it’s highest setting. Can you here your fan blowing? If you can hear it, does it sound weak or whining. This could signal that your blower motor is malfunctioning or needs to be replaced. If it doesn’t work at all, check the fuse for the blower motor. The fuse for your blower motor should be located in the fuse box under the dash. Most automobiles have the fuses clearly labeled. First take out the blower fan fuse with the removal tool provided in the fuse box. A blown fuse should be easy to identify. However if you are unsure, replace it with a similar rated fuse and try your blower again. If that fuse blows you may have a bad blower motor or a short in the circuit. In this case, you will need an authorized mechanic to fix it.

If the blower fan is working properly and you can only get cold air out of the defroster vents, you may have vacuum-system supply line problem. To check for this, look for a small black plastic tube going from the engine area through the dash. It is usually right by the refrigerant lines. Check this tube and see if it has holes or is not connected. If all of these little tips are not helping and you’re A/C doesn’t blow cold air no matter how many switches you turn on or off, you will probably need an certified mechanic. Good luck and stay cool!

How Does A Car Transmission Actually Work?


The transmission is one of the most important components of your car mechanics. Without the transmission you couldn't move faster than 20 miles per hour, bringing us back to cart and horse days. The transmission regulates the tire speed with the engine speed and sends power from the engine to the wheels.

You may think the engine is the most complicated component in car mechanics but actually it is the transmission, making it important to understand what the transmission does and how it does what it does. This article will cover the aforementioned topics and also covers signs of trouble with transmissions and when to get the transmission repair.

The transmission does a lot more than transfer power. It is the component at the back of the engine that connects the engine to the wheels. Its job is to keep the engine speed at a certain number of RPM (Revolutions Per Minute) because the engine works best when running at speeds that are not too fast and not too slow.

When your car is moving slowly the engine is moving much faster than the wheels. But at faster speeds the engine does not have to work as hard relative to the wheel speed. It is the transmission that makes this possible. There are a number of other gear gear positions in a typical transmission. These include "reverse," which sends the wheels turning backwards, "neutral," which disengages the engine from the car's wheels, and "park" which locks the wheels so the vehicle will not move.

There are many different components to the transmission. Planetary gear sets, hydraulic system, clutches and bands, seals and gaskets, and a torque converter are all components put together to deliver power to your car. Planetary gear sets adjust for different speeds and reverse. The hydraulic system sends oil to the gear system through the clutches and bands. Seals and gaskets are there to keep oil where it's supposed to be, covering the planetary gear sets, so everything runs smoothly. The torque converter is a clutch mechanism, allowing the gears to change without stopping.

There are many ways to tell if your transmission is working smoothly or giving you trouble. For example, failure to shift, or delays in shifting are a strong indication that your gear sets or torque converter is having problems.

Listen closely for odd noises. Thumping, grinding, banging, whining noises and lag in shifting can be a sign of problems. If the engine speeds up when you press the gas, but the car doesn't speed up accordingly, that tells you that your transmission isn't functioning right. Check your fluids. Red, pink or brown fluid under the car or having to continually fill the transmission with fluid are signs that you need to bring your transmission into the shop.

Preventative maintenance means thinking ahead and checking your car against all these problems, before they start. Change the transmission fluid every 25,000 miles, as a rule of thumb. This is done by taking your car or truck to a professional, because removing the transmission fluid pan is complicated and messy. Also it is best to let your mechanic take the pan out because they can check the fluid for metal shavings and other indications of problems.

So keep your transmission up to date by regular visits to your mechanic and watch (and listen) for signs that it is starting to have problems. If you follow these two guidelines, you shouldn't have extreme problems with your transmission.

Knowing how your transmission works can help when you are talking to your mechanic about the maintenance of your vehicle. If you ask him or her what's going on with your engine they will be glad to help you. Understanding a bit about your transmission will help you watch for problems and have them looked after before they develop into larger issues.

Warranty and Aftermarket Parts

Does the use of aftermarket parts, including performance chips, affects the new automobile warranty? Well, let us peep into what the laws of the land say.

The United States Code found at 15 U.S.C. 2301 Section 2302(c) states: "No warrantor of a consumer product may condition his written or implied warranty of such product on the consumer's using, in connection with such product, any article or service (other than article or service provided without charge under the terms of the warranty) which is identified by brand, trade, or corporate name…. 15 U.S.C. 2302(c)."

This provision was supplemented by Congress on 16 C.F.R. 700.10 section 102(c). It states in pertinent part: "No warrantor may condition the continued validity of a warranty on the use of only authorized repair service and/or authorized replacement parts for non-warranty service and maintenance. For example, provisions such as, 'This warranty is void if service is performed by anyone other than an authorized "ABC" dealer and all replacement parts must be genuine "ABC" parts,' and the like, are prohibited where the service or parts are not covered by the warranty. These provisions violate the Act in two ways. First, they violate the section 102 (c) ban against tying arrangements. Second, such provisions are deceptive under section 110 of the Act, because a warrantor cannot, as a matter of law, avoid liability under a written warranty where a defect is unrelated to the use by a consumer of "unauthorized" articles or service. This does not preclude a warrantor from expressly excluding liability for defects or damage caused by such "unauthorized" articles or service; nor does it preclude the warrantor from denying liability where the warrantor can demonstrate that the defect or damage was so caused."

It is clear from the foregoing that in the United States an automobile warranty is only inapplicable if the manufacturer proves that the aftermarket part was the cause of the defect or damage of the automobile in dispute.

What about warranty? There are pieces of jurisprudence about this.

Federal law precludes a dealer from voiding warranty just because of using aftermarket speed equipment, with only two exceptions: the warranty can be voided if the aftermarket part causes damage, or adversely affects the emissions or the emissions system. SEMA (Specialty Equipment Market Association) reported that a trade association representing specialty automotive parts manufacturers, the following quotes have been extracted:

"The vehicle manufacturer is not allowed to void the vehicle warranty just because aftermarket equipment is installed on the vehicle. This protection for consumers is the result of a parts self certification program developed by the Environmental Protection Agency (EPA) and the Specialty Equipment Market Association (SEMA).

These are the surrounding facts about aftermarket parts relating to warranties. Now that you are aware, be guided accordingly.

What You Need to Know About Engine Tune Ups, Engine Repair and Engine Replacement


Automotive engine repair and engine replacement are major undertakings that can be very expensive, just like car transmission system repair and replacement. As a vehicle owner you should, therefore, educate yourself on it. To avoid untimely engine repair and engine replacement, you also need to know about engine tune-ups. Your best source of information would be an automotive mechanic in Tampa whom you trust. He should likewise be an expert in auto repair and truck repair as well as auto inspection. Do not rely only on the handyman who does your auto oil change. It would be much better if your automotive mechanic works in a reputable Tampa automotive shop that supplies only genuine car parts like those from AC Delco.

An engine tune up is a routine preventive maintenance service done on the vehicle engine according to the instructions of the engine manufacturer. These instructions can be found in the vehicle’s owner’s manual along with the recommended schedule of frequency for each procedure. This may cover the examination of the ignition system and emission controls; the replacement of certain parts of the ignition system such as the contact breaker, distributor cap or rotor button, if necessary; corrections in the air-fuel mixture, carburettor idle speed and valve; adjustments in the cylinder head bolts; and the replacement of filters and spark plugs. In newer vehicle models, engine tune ups are not needed too often and can be done once in every ten years. They should never be ignored, though.

Even with proper engine tune ups, there are still various factors that can lead to engine breakdown. When this happens, there is often a choice between engine repair or engine replacement. With engine replacement still comes the choice between getting a brand new engine, a used engine or a remanufactured engine.

Engine repair and replacement is recommended by most automotive mechanics in Tampa only if the vehicle is less than ten years old, with a market value exceeding $2,000.00. Otherwise, the expense is not worthwhile and you are better off buying another vehicle.

Of course, engine repair is only possible if your engine is still repairable. Automotive mechanics in Tampa do not recommend repairing engines that have locked up or have been running for over 150,000 miles, making strange noises and burning oil.

For engine replacement, you will spend most if you go for a brand new engine, also called a crate engine. This is almost identical to your original engine or may even be better if the manufacturer has added upgrades to the same model. It comes with a solid warranty and ready for installation.

Less expensive than a brand new engine but not necessarily inferior to it is a remanufactured engine. This means a used engine has been totally overhauled and rebuilt with new components. Remanufactured engines meet and can even exceed the specifications and standards of original equipment manufacturer engines. They also come with solid warranties and ready for installation. Using a remanufactured engine that has been recycled is more ecologically sound and environmentally friendly.

The third option of getting a used engine is not recommended by reputable automotive mechanics in Tampa even if this is the cheapest choice. There is no guarantee that these used engines will last long.

Being diligent about your regular preventive maintenance procedures and engine tune ups will ensure that you will not have to spend for automotive engine repair and engine replacement sooner than necessary. At some point in the life of your vehicle, though, the need for engine repair and engine replacement is inevitable. If you are properly prepared, you can work well with your automotive mechanic in Tampa on this.
