Camshaft: Component Tests and General Diagnostics
Journal
1. Remove light scuffs, scores, or nicks from the camshaft machined surfaces with a smooth oil stone.
2. The camshaft must be replaced if camshaft journals are excessively worn or scored.
3. Measure the camshaft journal diameters and record.
4. If any journal is not 50.987-51.013 mm (2.0074-2.0084 inch) replace camshaft.
5. Camshaft journals can be refinished to accommodate 0.38 mm (0.015 inch) undersize bearing. If the journals do not "clean up," the camshaft must
be replaced.
Cam Lobe Inspection
INSPECT
Inspect the camshaft lobes for scoring and signs of abnormal wear. Lobe pitting in the general area of the lobe toe does not harm camshaft
operation. The camshaft should not be replaced unless the lobe lift loss has exceeded specification or pitting has occurred in the lobe lift area.
CAM LOBE LIFT
NOTE: The lift of the camshaft lobes can be checked with the camshaft installed. Refer to Lobe Lift Test (Installed) for procedure. See:
Lobe/Lobe Lift
1. Measure distance between major (A-A) and minor (B-B) diameters of each cam lobe with a Vernier caliper and record readings.
2. The difference in readings on each camshaft diameter is lobe lift.
3. If readings do not meet specification, replace camshaft.
