Main Bearing Cap Torque and Sequence

CRANKSHAFT BEARING CAP

Temporarily install the 10 crankshaft bearing cap bolts to the inside positions.





Push the crankshaft bearing cap by hand until the clearance between the crankshaft bearing cap and cylinder block is less than 6 mm (0.236 in.).
Bolt length 91 mm (3.58 in.)

Temporarily install the 10 crankshaft bearing cap bolts to the outside positions.
Bolt length 79.5 mm (3.13 in.)

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

Step 1:





Uniformly tighten the 20 crankshaft 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)

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

Step 2:





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





(l) Install and uniformly tighten the 10 crankshaft bearing cap bolts and 10 new seal washers in several steps in the sequence shown in the illustration.
Torque: 45 Nm (459 kgf-cm, 33 ft-lbf)
(m) Check that the crankshaft turns smoothly.
