Poly-V belt is a V-belt with longitudinal edges. This increases the frictional force. Poly-V belt is used to start the generator. Also it is used for water pump, servo-assisted steering gear, and fan. V-belts are made from rubber. Inside the belt there is a steel rod that is responsible for consistency of operation.

A common cause of failure is the poly-V belt break. Diagnosis of the faultinesses is carried out depending on the location of breakage. If the poly-V belt fails, it is easy to determine the cause. Before break formation there are characteristic noises caused by wear. It is necessary to replace the belt to avoid failure. You should always watch over the belt state. Defective poly-V belt indicates engine overheating.

The main poly-V belt starts the generator. It is not difficult to replace the belt, but it is hard-to-reach. First, you need to sort the tension out, and then to remove the damaged belt. When attaching the new V- belt, tension should be the same as pulleys’ overloading is possible. It is necessary to test the belt when the engine is on.
