Inspection
1. Thrust clearance
• Measure the crankshaft end play at the cente
r
journal of the crankshaft.
• Do this before removing the crankshaft bearing
caps. If the measured value exceeds the
specified limit, the crankshaft thrust bearing
must be replaced.
Axial play of the crankshaft mm (in)
Standard 0.10 (0.004)
Limit 0.30 (0.012)
Note:
Measure the thrust clearance before dismounting.

2. Main bearing clearance
• Remove the crank case.
Set out disassembled main bearings in the order of the numbers.
• Remove the crankshaft. Remove the main
bearings.
• Clean the crankshaft journal and upper and
lower bearings.
• Check the bearings for damage or excessive
wear.

If you find damage or excessive wear, replace the bearings in pairs.

• Place the upper bearings and the crankshaft on
the cylinder block. Install the crankshaft so that
it is horizontal.
Note:
Turn the crankshaft about 30 degrees to allow the
bearings to settle in.
• Place plastigage on the crankshaft journal as
shown.
• Place the lower bearings at original positions on
the bearing cap.

Note:
Do not turn the crankshaft after you have tightened the
bearing cap.
• Loosen the bolts and gently remove the bearing
cap.
• Measure the widest part of the Plastigage
flattened by tightening the bearing cap to
determine the clearance.
Journal oil clearance mm (in)

•
If the journal oil clearance exceeds the limit,
replace the main bearings altogether or the
crankshaft.
• Remove the Plastigage from the bearings and
the crankshaft.

Inspection of the crankshaft
• Check the crankshaft journal and crank pin
surfaces for wear and damage. Check the oil
seal contact surface for excessive wear and
damage.
• Check the oil port for clogging.
3. Crankshaft run-out
Carefully set the crankshaft on the V block. Slowl
y
turn the crankshaft to measure the run-out. If the
crankshaft run-out exceeds the limit, replace the
crankshaft.
Crankshaft run-out mm (in)
Standard 0.05 or less (0.0020 or less)
