Inspection and Repair for Bearings

1. Inspect 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 : 0.06 mm–0.24 mm

(0.0024 in–0.0094 in)

Limit : 0.30 mm (0.0118 in)

Main Bearing Clearance

1. Remove the bearing caps and measure the oil

clearance.

2. Remove the main bearing cap fixing bolts in the

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

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.

11. 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 : 0.019 mm–0.043 mm

(0.0007 in–0.0017 in)
