Rocker Arm / Rocker Arm Shaft Inspection
1. Mark or tag rocker arms and shafts to keep them in their
respective locations for assembly.
2. Slide rocker arm shafts from carrier.
3. Inspect each rocker arm roller. Roller surface should be
smooth and radial movement should be minimal. Roll a
smooth flat rod across the roller, applying firm downward
pressure on roller while observing roller movement. Roller
should turn smoothly without binding. Replace rocker arm
if roller surface is damaged, or if roller does not turn
smoothly.
4. Measure I.D. of rocker arms and O.D. of rocker arm shafts.
Measure shaft bore in cam carrier. Compare to
specifications (See “Engine Specifications - EH085OLE-
011” on page 5.5).
