Crankshaft Main Bearing

CRANKSHAFT BEARING

Step 1:





Install and uniformly tighten the 20 main bearing cap bolts in the sequence shown in the illustration.
For inside position - Torque: 61 Nm (622 kgf-cm, 45 ft-lbf)
For outside position - Torque: 27 Nm (275 kgf-cm, 20 ft-lbf)

Step 2:





Mark the front of each bearing cap bolt with paint.
Tighten the bearing cap bolts another 90° in the order shown in step 1.
Check that the painted marks are now at a 90° angle to the front.
Check that the crankshaft turns smoothly.






Install and uniformly tighten the 10 main bearing cap bolts and 10 seal washers in several steps, in the sequence shown in the illustration.
Torque: 45 Nm (459 kgf-cm, 33 ft-lbf)
