Maintaining Your Vehicle: Drive Belts

Belts are used in automobiles to connect and drive two shafts to the motion of a rotary by using pulleys in a series. Various accessories mounted to the engine are powered through the use of this rotary motion. Pumps, exhaust fans and air compressors are all examples of accessories powered in this way and are essential to the successful operation of the vehicle. 

Identifying different belts:

V-belts are designed to provide high-traction power and to fit into a V shaped groove. Another belt that provides high-traction power is the Poly-V belt. This belt is flat on the outside but has many V-shaped grooves on the inside. The V-Link belt is similar to the above V-belts, but is open-ended and does not need meal clamps. Using a V-Link is a last resort for when other belts will not reach or fit as they are quite costly and will only carry a small load.

Flat belts function well at high speeds despite the lack of traction and their tendency to slip. They are much lighter in weight than other belts. The Timing belt is one of the most important belts and is quite different to other types. It does not require friction to function, nor does it it have teeth. It also has a much smaller power capacity in comparison with other belts.

What do drive belts do?

The purpose of drive belts is to drive a variety of external parts of the engine. Even though these belts are very inexpensive, they have the ability to put a stop to a functioning vehicle if they break. Without the belt to drive the vehicle component, there can be no motion or function from that component. One of the many accessories to rely on a drive belt is the water pump. The water pump is designed to circulates water through the vehicle’s system, thus keeping it cool. If the water pump stops working, which happens instantly when the drive belt breaks, it takes only a short time for the engine to overheat. The serpentine belt drives several components of the vehicle so if this one breaks, many functioning parts are immediately affected.

What causes a belt to break?

Drive belts are made of inexpensive rubber. Over time, belts suffer normal wear and tear and this can cause them to dry out or crack. The belt will break as wear and tear compromises the integrity of the belt.

Are drive belts easy to replace?

Depending on the location of the belt and your mechanical aptitude, it may be a simple process to replace a drive belt. A serpentine belt can be pretty complicated so it is probably best left to the professional mechanic. In most cases the serpentine belt will only need to be changed every thirty-five thousand miles. Both the serpentine belt and the timing belt can last up to sixty thousand miles.
