1. Clean the crankpin and crankpin bearing.
2. Put
a
strip
of plastigauge on the center of the
crankpin.
NOTE
• Do not put
the plastigauge into the crankpin
oil hole.
3. Install the connecting rod cap.
4. Tighten the connecting rod screws to the specified
torque.
NOTE
• When you tighten the connecting rod
screws, do not move the crankshaft.

5. Remove the connecting rod cap again.
6. Measure
the
width
that it becomes flat with the
scale to get the oil clearance.
NOTE
• If the clearance
more than the service limit,
replace the crankpin bearing.
• If the same dimension bearing is not
applicable because of the crankpin wear,
replace it with an undersize one.
