CRANKSHAFT

Install the crankshaft bearing cap bolts.

The crankshaft bearing cap bolts are tightened in 2 progressive steps.

Step 1





Install and uniformly tighten the 16 crankshaft bearing cap bolts in several steps and in the sequence shown in the illustration.

Torque 61 Nm (622 kgf-cm, 45ft-lbf)

If any of the crankshaft bearing cap bolts does not meet the torque specified, replace it.

Step 2





Mark the front of the bearing cap bolts with paint.
Retighten the bearing cap bolts 90° in the sequence shown in the illustration.
Check that the painted mark is now at a 90° angle to the front of the engine.
