Powertrain Engines

Crankshaft

• The crankshaft for the L8 and LF engine has four counterweights, while the crankshaft

for the L3 engine has eight counterweights.

• In addition, the crankshaft for the L3 engine is equipped with a drive gear for the

balancer shafts.

• The crankshaft features no key for the installation of the crankshaft sprocket and the

crankshaft pulley, i.e. solely the clamping force of the lock bolt secures both components

on the crankshaft.

• The crankshaft pulley has a pulse wheel for the CKP (Crankshaft Position) sensor

signals. For this reason, the crankshaft pulley must be fixed to the engine front cover

using a detent bolt (M6 x 1.0) before tightening the crankshaft pulley lock bolt.

• The crankshaft pulley lock bolt is a torque-to-yield bolt, which must be tightened in

several stages (refer to the workshop manual for details).

NOTE: The crankshaft pulley lock bolt must not be re-used.
