(D) Flywheel and Crankshaft
Crankshaft Side Clearance
1. Set a dial indicator with its tip on the end of the crankshaft.
2. Measure the side clearance by moving the crankshaft to the front
and rear.
3. If the measurement exceeds the allowable limit, replace the
thrust bearings.
4. If the same size bearing is useless because of the crankshaft
journal wear, replace it with an oversize one referring to the table
and figure.
(Reference)
• Oversize thrust bearing
• Oversize dimensions of crankshaft journal.

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.
