Put marks (stake) on screw (1) carefully. Too much force pushes the shaft extension into the camshaft and takes away all end clearance.
8. Install screw (1) and tighten it to a torque of 7.9 0.6 N m (70 5 lb in). Put marks (stake) on the screw in two places with a hammer and punch.9. After marks (stake) are put on screw (1), the end clearance for the gear and weight assembly must be 0.08 to 0.94 mm (.003 to .037 in). This end clearance will prevent binding against the washer, camshaft end, or camshaft gear.End By:a. install timing gear cover & oil pump
