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: 63-973-64.003 mm (2.5190-2.5198 inch).
Connecting Rod: 53.983-54.003 mm (2.1253-2.1261 inch).
4. The bearing journal Out-Of-Round Limit is:
Main And Connecting Rod: 0.008 mm (0.0003 inch).
5. If a main journal or connecting rod journal diameter is less than the specification, grind the journal to match an undersize bearing.
