Oil Clearance between Crankshaft Journal and Crankshaft
Bearing 2 and Crankshaft Bearing 3
1. Put a strip of plastigage on the center of the journal.
2. Install the bearing case and tighten the bearing case screws 1 to
the specified torque, and remove the bearing case again.
3. Measure the amount of the flattening with the scale, and get the
oil clearance.
4. If the oil clearance exceeds the allowable limit, replace the
crankshaft bearing 2 (crankshaft bearing 3).
5. If the same size bearing is useless because of the crankshaft
journal wear, replace it with an undersize one referring to the
table and figure.
NOTE■
• Be sure not to move the crankshaft while the bearing case
screws are tightened.
