2.3.4 Crankshaft
2.3.4.a Crankshaft End Clearance
1. Push on the end of the crankshaft to seat it toward the
flywheel end of the engine block.
2. Attach, then zero a dial indicator on the forward end of
the crankshaft.
3. Measure the end play by pulling the crankshaft for-
ward.
4. If the measurement exceeds the allowable limit re-
place the thrust bearings.
5. If the new thrust bearings do not correct the exces-
sive end clearance condition, over size thrust bea-
rings may be necessary.

The crankshaft journal must be fine--finished to higher than

2.3.4.b Crankshaft Alignment
1. Support the crankshaft with V blocks on a surface
plate at both end journals. Set a dial indicator with its
tip on the intermediate journal, perpendicular to the
journal.
2. Rotate the crankshaft on the V blocks and get the
misalignment (half of the measurement).
3. If the misalignment exceeds the allowable limit, re-
place the crankshaft.
