Crankshaft Main Bearing
MAIN BEARING CAPTemporarily 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 105.5 to 107.5 mm (4.15 to 4.23 in.)
Install the crankshaft bearing cap bolts.
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 N*m (622 kgf/cm, 45 ft. lbs.)
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.
Tighten the bearing cap bolts another 90° in the order above.
Check that the painted mark is now at a 90° angle to the front.
Install and uniformly tighten the 8 main bearing cap bolts in several steps and in the sequence shown in the illustration.
Torque 52 N*m (525 kgf/cm, 38 ft. lbs.)
