Inspection and Repair

1. Crankshaft

Set the dial indicator as shown in the illustration and
measure the crankshaft thrust clearance. If the thrust
clearance exceeds the specified limit, replace the
thrust bearings as a set.

Thrust Clearance
Standard : 0.01 mm–0.02 mm

(0.0004 in–0.0008 in)

Limit : 0.21 mm (0.0118 in)

014RW079

Main Bearing Clearance

1. Remove the bearing caps and measure the oil

clearance.

2. Remove the main bearing cap fixing bolts.

Arrange the removed main bearing caps in the
cylinder number order.
Remove the main bearings.

3. Remove the crankshaft.

Remove the main bearings.

4. Clean the upper and lower bearings as well as the

crankshaft main journal.

5. Check the bearings for damage or excessive wear.

The bearings must be replaced as a set if damage or
excessive wear is discovered during inspection.

6. Set the upper bearings and the thrust washers to their

original positions.
Carefully install the crankshaft.

7. Set the lower bearings to the bearing cap original

position.

8. Apply plastigage to the crankshaft journal unit as

shown in the illustration.

014RW055

9. Install main bearing caps, and tighten each bolt to the

specified torque.

Main bearing caps bolts.
Torque:
1st step: 50 N·m (37 lb ft)
2nd step: 45

°

3rd step: 15

°

Torque : 39 N·m (29lb ft)

10. Measure the plastigage width and determine the oil

clearance. If the oil clearance exceeds the specified
limit, replace the main bearings as a set and/or
replace the crankshaft.

Standard : 0.015 mm–0.04 mm

(0.0007 in–0.0016 in)

Limit : 0.12 mm (0.0047 in)
