At the front of the crankshaft, a tuned torsional mass damper is incorporated into the crankshaft pulley.
The pulley is located on two woodruff keys which are located in slots in the crankshaft. The woodruff keys are a press fit in the slots and must be correctly aligned.
If the pulley is removed, a new friction washer must be located between the timing chain drive sprocket and the crankshaft pulley and a new pulley bolt must also be used.
The crankshaft pulley/mass damper assembly is not a serviceable component and must not be disassembled.
