Clean the crankpin and crankpin bearing.
2. Put a strip of plastigage (Code No. 0790990241) on the center
of the crankpin.
3. Install the connecting rod cap and tighten the connecting rod
screws to the specified torque, and remove the cap again.
4. Measure the amount
of
the flattening with the scale, and get the
oil clearance.
5.
If the oil clearance exceeds the allowable limit, replace the
crankpin bearing.
6. If the same size bearing is useless because of the crankpin
wear, replace it with an undersize one referring to the table and
figure.
NOTE
Never insert the plastigage into the crankpin
oil
