4) Measure the thrust clearance of crankshaft at
center bearing by using thickness gauge. If the
thrust clearance is not within the standard, replace
the bearing.

Crankshaft thrust clearance:

Standard

0.030 — 0.115 mm (0.0012 — 0.0045 in)

5) Inspect individual crankshaft bearings for signs
of flaking, seizure, melting and wear.
6) Measure the oil clearance on each crankshaft
bearing using plastigauge. If the measured value is
out of standard, replace the defective bearing with
an undersize one, and replace or recondition the
crankshaft as necessary.

Crankshaft oil clearance:

Standard

0.010 — 0.030 mm (0.0004 — 0.0012 in)

Unit: mm (in)
