### Removal Procedure

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).

### Cleaning and Inspection Procedure

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

• | Flat spots

• | Excessive scoring and pitting

• | Ensure the roller spins freely

• | Inspect the rocker arm valve tip area (2)

• | Inspect the rocker arm stationary hydraulic lash adjuster (SHLA) pivot area (3)

• | Replace the rocker arm as required.

### Installation Procedure

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.
