Rocker Arm Cleaning and Inspection
1. Clean all parts thoroughly. Make sure all oil passages are open.

CAUTION: Do not attempt to true surfaces by grinding. Check the rocker arm pad, side rails and seat for excessive wear, cracks, nicks or
burrs. Check the rocker arm seat bolt for stripped or broken threads. Install new components as necessary or engine damage may occur.
3. Inspect the rocker arm push rod bore for nicks, scratches, scores or scuffs.
4. Inspect the pad at the valve end of the rocker arm for indications of grooving, scuffing or abnormal wear.
