General information

The drive of camshafts of both heads of cylinders is carried out by one gear belt. The reverse (smooth) side of the same belt is used for the drive of the water pump.

Teeths of a driving belt have specially developed rounded profile promoting decrease in the general noise background. The basis of a belt is made by the strong and rigid fibers covered with waterproof fabric and heat-resistant rubber.
