All mentioned in this section can be replaced by parts mounted on the car engine. Location chains drive the camshaft and all related components shown in Fig. 95 a and 95 b. In Fig. 96 shows a drive mechanism of a camshaft assembly. Chain drive camshaft actuates the sprocket of the camshaft sprocket of the fuel pump, and itself is driven by a crankshaft sprocket. The chain is supported by two straps - dampers. Tensioning chain regulated by hydraulic tensioner disposed in the crankcase, and acting on the tensioning shoe chain made of light metal. Camshaft drive sprocket is fixed to the shaft key and bolted M8. The second circuit is designed for a small oil pump drive. This circuit is driven by a second crankshaft sprocket (on the crankshaft of the engine mounted twin star) and is equipped with its own tensioning device.
