CRANKSHAFT













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 100.0 to 102.0 mm (3.937 to 4.016 in.)

Install the 8 main bearing cap bolts to the outside positions.

Bolt length 105.5 to 107.5 mm (4.154 to 4.232 in.)

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 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 and seal washers in several steps, in the sequence shown in the illustration.

Torque 52 Nm (530 kgf-cm, 38 ft-lbf)

Bolt length:
45 mm (1.77 in.) for bolt A
30 mm (1.18 in.) for except bolt A


There are 5 sizes of standard bearings, marked "1", "2", "3", "4" and "5" accordingly.

PISTON SUB-ASSEMBLY WITH CONNECTING ROD

Step 1





Install and alternately tighten the bolts of the connecting rod cap in several steps.

Torque 25 Nm (255 kgf-cm, 18 ft-lbf)

Step 2





Mark the front side of each connecting cap bolt with paint.
Tighten the cap bolts another 90° as shown in the illustration.
Check that the painted mark is now at a 90° angle to the front.
Check that the crankshaft turns smoothly
