CRANKSHAFT














There are 6 sizes of standard bearings. For the No. 1 and No. 5 position bearings, use bearings marked 4, 5, 6, 7, 8 or 9. For other bearings, use bearings marked 3, 4, 5, 6, 7 or 8.





Example:
Cylinder block "07" + Crankshaft "06" = Total number 13 (Use upper bearing "6" and lower bearing "7")

A = Cylinder block number mark
B = Crankshaft number mark

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.

PISTON AND CONNECTING ROD

Step 1:




Install and alternately tighten the bolts of the connecting rod cap in several steps.
Torque 40 Nm (408 kgf-cm, 30 ft-lbf)





Step 2:
Mark the front side of each connecting rod cap bolt with paint.
Tighten the cap bolts 90° as shown in the illustration in the order in step 1.
Check that the painted marks are now at a 90° angle to the front.
Check that the crankshaft turns smoothly.
