Camshaft: Testing and Inspection
Journal
Diameter
1. Measure each journal twice, 90 degrees apart, to determine journal wear, size, and out of round.
2. Check measurements against specifications.
3. If journals are excessively out of round or worn, regrind to a standard undersize. If journals are too worn to be refinished to an available undersize,
camshaft will have to be replaced.
Journal Oil Clearance
1. Measure camshaft bearings and camshaft bearing journals.
2. Subtract size of journal from the size of its bearing.
3. Check clearance against specifications.
4. If clearance is excessive, but camshaft journals are within specifications, simply install new bearings. If both bearings and journals are worn, turn
camshaft journals to a standard undersize and install new bearings.
