Camshaft - Inspection

INSPECTION

1. Inspect the camshaft bearing journals for damage or binding. If the journals are binding, check the cylinder head for damage. Also check the cylinder head oil holes for clogging.
2. Check the camshaft lobe and the bearing surfaces for abnormal wear and damage. Replace the camshaft if it is defective.
3. Measure the lobe actual wear and replace the camshaft if it is out of limit. The standard value is 0.001 in. (0.0254 mm). The wear limit is 0.010 in. (0.254 mm).
