Crankshaft Alignment
1. Support the crankshaft with V block on the surface plate and set
a dial indicator with its tip on the intermediate journal at right
angle.
2. Rotate the crankshaft on the V block and get the misalignment
(half of the measurement).
3. If the misalignment exceeds the allowable limit, replace the
crankshaft.

Oil Clearance between Crankpin and Crankpin Bearing
1. Clean the crankpin and crankpin bearing.
2. Put a strip of plastigage 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.
• Never insert the plastigage into the crankpin oil hole.
• Be sure not to move the crankshaft while the connecting rod
screws are tightened.
