CRANKSHAFT

Step 1:





Using several steps, uniformly install and tighten the 10 bearing cap bolts in the sequence shown in the illustration.

Torque 20 Nm (204 kgf-cm, 15ft-lbf)

Step 2:

Tighten the 10 bearing cap bolts again in the sequence shown in the illustration.

Torque 40 Nm (408 kgf-cm, 30ft-lbf)

If a crankshaft bearing cap bolt does not meet the specified torque, replace it.

Step 3:





Mark the front of the bearing cap bolts with paint.
Tighten the 10 bearing cap bolts 90° in the same sequence.
Check that the paint marks are now at a 90° angle to the front.
Check that the crankshaft turns smoothly.




















There are 4 sizes of standard bearings, marked "1", "2", "3" and "4" accordingly.





EXAMPLE
Cylinder block (A) "3" + Crankshaft (B) "4" = Total "7"
Select the bearing marked "3".
