ter outward, loosen the camshaft bearing caps in
gradual steps.
6. Remove the rocker arms, shafts and bearing
caps as an assembly.
*It is essential that all parts be kept in the
same order and orientation for reinstallation.
Be sure to mark and separate parts, so parts
will not be mixed during reassembly.
7. Disassemble rocker shaft assembly. Starting
at rear bearing cap, slide each piece off shafts.
*Inspect the roller surfaces of the rockers.
Replace if there are any signs of damage or
if the roller does not turn smoothly. Check
the inside bore of the rockers and lifter for
wear.

5. If disassembly is required, keep all parts in
the exact order of removal. Inspect the roller surfaces
of the rockers. Replace if there are any signs of dam-
age or if the roller does not turn smoothly. Check the
inside bore of the rockers and the adjuster tip for
wear.
To install: 6. Lubricate the rocker shaft with clean engine
oil and install the rockers and springs in their proper
places.
7. Install the rocker shaft assemblies on the en-
gine. Tighten the bolts gradually and evenly to 21-25
