Crankshaft: Testing and Inspection
Journal
PROCEDURES
1. Measure the main and connecting rod journals. Measure the journals in eight locations.
2. Write down the figures on a sketch to give a profile of each journal. A study of the readings will tell if the crankshaft is usable as is, if it must be
reground, or if it must be replaced.
3. The bearing journal diameter specification is:
Main Bearing: 67.483-67.503 mm (2.6568-2.6576 inch).
Connecting Rod: 52.988-53.003 mm (2.0861-2.0867 inch).
4. Check the main and connecting rod bearing journal for out-of-round.
5. If a main journal or connecting rod journal diameter is less than the specification, grind the journal to match an undersize bearing.
