- If any of the main bearing cap bolts is broken or deformed, replace it.
a. Apply a light coat of engine oil on the threads and under the heads of the main bearing cap bolts.
b. Install and uniformly tighten the 10 bolts of the main bearing caps in several passes, in the sequence shown.
Torque: 39 Nm (400 kgf-cm, 29 ft. lbs.)
If any one of the main bearing cap bolts does not meet the torque specification, replace the main bearing cap bolt.
c. Mark the front of the main bearing cap bolt with paint.
d. Retighten the main bearing cap bolts by 90° in the numerical order shown.
e. Check that the painted mark is now at a 90° angle to the front.
f. Check that the crankshaft turns smoothly.
g. Check the crankshaft thrust clearance.
