Crankshaft Main Bearing

CRANKSHAFT

Temporarily install the 10 crankshaft bearing cap bolts to the inside positions.






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.


Install and uniformly tighten the 10 crankshaft bearing cap bolts and 10 new seal washers.






Torque 45 Nm (459 kgf-cm, 33 ft-lbf)

MAIN BEARING SIZE CODES

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
