Rocker Arm Assembly: Service and Repair

REMOVAL
1. Remove cylinder head cover and gasket.





2. Remove the rocker arm bolts and pivots (Fig. 16). Place them on a bench in the same order as removed.
3. Remove the push rods and place them on a bench in the same order as removed.

INSTALLATION
1. Rotate the crankshaft until the "V8" mark lines up with the TDC mark on the timing chain case cover. This mark is located 147' ATDC from the No. 1 firing position.
2. Install the push rods in the same order as removed.
3. Install rocker arm and pivot assemblies in the same order as removed. Tighten the rocker arm bolts to 28 Nm (21 ft. lbs.) torque.

CAUTION: DO NOT rotate or crank the engine during or immediately after rocker arm installation. Allow the hydraulic roller tappets adequate time to bleed down (about 5 minutes).

4. Install cylinder head cover.
