Initial Inspection and Diagnostic Overview

CAUTION If the camshaft is not inspected or assembled within 2-4 hours, of cleaning, coat with engine oil to prevent rust.

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. 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.
4. Check camshaft bores for size, taper, roundness, alignment and finish. If any of these exceed the limits given in Specifications, install new camshaft bearings or replace cylinder heads.
