Diameter
Standard 10.8 to 11.0 mm (0.4252 to 0.4331 inch)
Minimum 10.70 mm (0.4213 inch)
Main Bearing Cap
Confirm the front marks and numbers of the main bearing caps and install the bearing caps on the cylinder block.
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 inch) by marking the 2 internal bearing cap bolts as a guide.
Bolt length 100.0 to 102.0 mm (3.937 to 4.016 inch)
Using a plastic-faced 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 105.5 to 107.5 mm (4.154 to 4.232 inch)
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. lbs.)
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 another 90° in the order shown in step 1.
Check that the painted mark is now at a 90° angle to the front.
Check that the crankshaft turns smoothly.
Install and uniformly tighten the 8 main bearing cap bolts in several steps, in the sequence shown in the illustration.
Torque 52 Nm (530 kgf-cm, 38 ft. lbs.)
Bolt length:
45 mm (1.77 inch) for bolt A
30 mm (1.18 inch) for except bolt A
Check that the crankshaft turns smoothly.
