Inspection (Camshaft)

Inspect camshaft journals, fuel pump drive cam, and valve lobes for wear or damage. Fuel pump drive cam height should be 1.46" (37.1). Measure camshaft journal diameter and camshaft end play. Measure camshaft lobe height for intake and exhaust cam lobes. Replace camshaft if measurements are not within specifications.
