Oil Clearance between Crankpin and Connecting
R<>d Bearing . . . . - ­
1. Put a strip of Plastigage lengthwise into the bearing cap.
2. Install the bearing cap noting that the gauge may not meet
with the hole on the crank pin, tighten the screws to
the specified torque, and remove the cap.
3. Measure the amount of the flattening with the scale and
get the oil clearance.
4. If the clearance exceeds the allowable limit, replace the
connecting rod bearing.
5. If the same size bearing is useless because of the crank ­
shaft journal wear, replace it with an undersize one re ­
ferring to the table and the figure.
• NOTE:
• Be sure not to move the crankshaft while the bearing cap
screws are tightened.
