Camshaft: Testing and Inspection
End Play
1. Push camshaft toward rear of engine. Install Dial Indicator with Bracketry TOOL-4201-C or equivalent so indicator point is on camshaft sprocket
attaching bolt.
CAUTION: Prying against the camshaft gear with the valve train load on the camshaft can break or damage the gear. Therefore, the rocker arm
adjusting nuts must be backed off or the rocker arm and shaft assembly must be loosened sufficiently to free the camshaft. After checking the
camshaft end play, resecure valve train components.
2. Zero dial indicator. Pull camshaft forward and release it. Compare dial indicator reading with specifications. If end play is excessive, replace
camshaft thrust plate.
3. Remove dial indicator.
4. After replacing thrust plate, check end play again. If it is still out of specified range, inspect camshaft and cylinder block for excessive wear.
