Visual Inspection

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. If the camshaft journals on cylinder heads are excessively worn or scored, replace the cylinder heads.
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.
5. Inspect the camshaft journals on the cylinder head and camshaft journal caps. If excessive wear or galling is present, replace cylinder head.
