The drive of both distribution halls of the engine is carried out by means of a toothed belt that drives one of the camshafts. The second camshaft is driven by a separate chain from a camshaft driven by a toothed belt. The toothed belt is located on the gears of the camshafts, crankshaft and intermediate shaft. The toothed belt is completely isolated from the outer mudguard, the crankshaft gear is installed thanks to the V-groove in the crankshaft and the protrusion on the inside of the crankshaft wheel. The service life of the belt should be 100,000 km.
The belt tension is created by means of an integrated tension roller with an adjusting eccentric.
