Crankshaft Main Bearing

MAIN BEARING CAP





Install and uniformly tighten the 10 main bearing cap bolts in the sequence shown in the illustration.

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






Make the front of the bearing cap bolts with paint.
Further tighten the bearing cap bolts by 90° in the numerical order shown in the illustration.
Check that the paint mark is now at a 90° angle to the front.
Check that the crankshaft turns smoothly.
Check the crankshaft thrust clearance.
