Checking Valve Timing

Install a quadrant on crankshaft damper. Remove right rocker arm assembly. Install Dial Indicator Tool 6565 and Indicator Adapter Tool 6565-AB on cylinder head using holding Fixture Tool 4201-C. Pushrod must be in lifter socket and actuating point of indicator in same plane as pushrod movement. Make sure timing pointer is not bent. Turn engine slowly until lifter is on heal of camshaft lobe. Set indicator on zero and turn engine slowly until indicator registers cam lobe lift as shown in "Camshaft" table below. Compare crankshaft degrees indicated on quadrant with "Valve Timing" table below. Rotate engine to check valve closing specifications in same manner. If reading not correct, check for bent pointer, worn timing chain or sprocket before replacing camshaft.
