1. Remove the camshaft from the left cylinder head. Refer to Camshaft Replacement - Left Side.

Important: If the rocker arms are being reused, they must be reinstalled in their original location.

Important: Record the rocker arm positions during removal.

2. Remove the rocker arm (1) from the cylinder head  (2).

Inspect the rocker arm roller (1) for the following:

1. Apply a liberal amount of commercially available camshaft/lifter prelube or equivalent to the pivot pocket (1), roller (2) and valve slot (3) areas of the camshaft followers.




Important: The rocker arm (1) must be positioned squarely on the valve tip so the full width of the roller will completely contact the camshaft lobe. If the rocker arms are being reused, they must be reinstalled in their original location.

2. Place the rocker arm in position on the valve tip and stationary hydraulic lash adjuster (SHLA). The rounded head end of the arm seats on the SHLA while the flat end seats on the valve tip.
3. Clean the camshaft journals and carriers with a clean, lint-free cloth.
4. Reinstall the camshaft. Refer to Camshaft Replacement - Left Side.
