Valve rocker arms and unit injector rocker arms can move on the shaft after the bolts have been removed. The shaft should be kept level when removed from the cylinder head. To avoid possible personal injury, keep fingers clear of the valve rocker arms and the unit injector rocker arms when lifting the assembly from the cylinder head.

1. Remove shaft (3), valve rocker arms (1), and unit injector rocker arms (2) as a unit with Tooling (A).

2. Repeat Step 1 for the remainder of the rocker arm assemblies.
