Rocker Assembly
Disassembly and Inspection
NOTE: Orientation of the components is important
for reassembly. Mark components as needed before
disassembly.
1. Remove the valve cover and secondary air injection pipe
as an assembly.
2. Loosen each of the four cylinder head nuts evenly 1/4 turn
each time in a cross pattern until loose.
3. Remove the nuts and tap the rocker assembly with a plastic
hammer to loosen, then remove. Mark or tag rocker arms
to keep them in order for assembly.
4. Inspect each rocker arm cam follower surface. If there is
any damage or uneven wear, replace the rocker arm.
NOTE: Always inspect camshaft lobes if rocker arms are
worn or damaged.
5. Remove each rocker arm shaft using a hex bolt. NOTE:
Place the hex bolt head in a vise and lightly tap the rocker
housing with a non-marring hammer to pull the rocker
arm shafts.
6. Measure O.D. of rocker shafts for out-of-round. Inspect for
wear or damage. Replace if excessive wear is evident.
NOTE: Orientation of the rocker shafts is important for
reassembly. Place only the exhaust rocker shaft into the
exhaust side of the cam support.
