Pic. 2.14. Crankshaft Vibration Damper: 1 - vertical projection; 2 - section; 3 - gear wheel of the crankshaft pulley; 4 - pulley mounting hole; 5 - torsional vibration damper
The vibration damper, which prevents vibrations of the crankshaft, is integrated in the crankshaft sprocket. The dowel keyway, which is usually used to install the pulley on the crankshaft, is missing. To align the crankshaft pulley on the crankshaft, the alignment holes on the engine front cover and crankshaft pulley must be used. The crankshaft pulley anchor bolt has a tightening torque in the plastic zone, tightening is carried out in two steps. This ensures the stability of the bolt axis during tightening (pic. 2.14).
