CRANKSHAFT MAIN BEARING CAP BOLTS
Apply engine oil to the upper bearing, then place the crankshaft on the cylinder block.





Confirm the projection and numbers of the main bearing caps and install the bearing caps on the cylinder block.

HINT: A number is marked on each main bearing cap to indicate the installation position.

Apply a light coat of engine oil to the threads and under the heads of the bearing cap bolts.
Temporarily install the 8 main bearing cap bolts to the inside positions.





Insert the main bearing cap by hand until the clearance between the main bearing cap and the cylinder block is less than 6 mm (0.23 in.) by marking the 2 internal bearing cap bolts as a guide.
Bolt length: 100 to 102 mm (3.94 to 4.02 in.)





Using a plastic hammer, lightly tap the bearing cap to ensure a proper fit.
Apply a light coat of engine oil to the threads and under the heads of the 8 main bearing cap bolts.





Install the 8 main bearing cap bolts to the outside positions.
Bolt length:





Install the crankshaft bearing cap bolts.

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

Step 1





Install and uniformly tighten the 16 main bearing cap bolts in the sequence shown in the illustration.
Torque: 61 Nm (622 kgf-cm, 45 ft-lbf)
If any of the main bearing cap bolts does not meet the torque specified, replace it.

Step 2





Mark the front of the bearing cap bolts with paint.
Retighten the bearing cap bolts by 90° in the order above.
Check that the painted mark is now at a 90° angle to the front.





Install 8 new seal washers and uniformly tighten the 8 main bearing cap bolts in several steps and in the sequence shown in the illustration.
Torque: 26 Nm (265 kgf-cm, 19 ft-lbf)
Bolt length:
