Rocker Arm Assembly: Service and Repair
Valve Rocker Arm, Shaft, and Push Rod Replacement
Removal Procedure
Important: Rotate the engine until the mark on the crankshaft balancer is at the 2 o'clock position.
Rotate the crankshaft counter clock wise 88 mm (3 1/2 inch), aligning the crankshaft balancer mark with the first lower water pump bolt, about 12:30.
This will position the engine so that no valves are close to the piston crown.
1. Disconnect both the battery negative cables from the batteries.
2. Remove the valve rocker arm cover from the cylinder head.
3. Remove the valve rocker arm shaft bolts from the cylinder head.
4. Remove the valve rocker arm shaft with the valve rocker arm.
Important: The push rods must be installed in the original position as they were removed. This is because the push rods have different degrees of
hardness at each end. A paint stripe identifies the upper end of the push rod. If the paint stripe is not visible, mark the push rod on the upper end as the
push rods are removed.
5. Remove the push rods from the engine block.
