Oil Clearance between Crankshaft Journal and Crankshaft
Bearing 1
1. Measure the O.D. of the crankshaft journal with an outside
micrometer.
2. Measure the I.D. of the crankshaft bearing 1 with an inside
micrometer, and calculate oil clearance.
3. If the clearance exceeds the allowable limit, replace the
crankshaft bearing 1.
4. 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.
