A timing belt is a part of the drive system that transmits the rotation of the crankshaft to the camshaft. Unlike the timing chain, the timing belt is made of a belt material with teeth that engage the corresponding sprockets on the crankshaft and camshaft.
The belt is usually made of a high-strength material such as rubber or neoprene and has a reinforcing fibre layer. This ensures reliable power transmission and a long belt life.
Regular inspection and maintenance of the timing belt is of great importance, as a worn or damaged belt can cause the drive system to fail. It is important to check the belt for signs of wear such as cracks, wear or looseness and replace it according to the manufacturer's specifications to ensure reliable performance of the drive system.
