Removal procedure
1. Remove the camshafts from the respective cylinder head. See «Camshaft» in this section.
Attention! If the rocker arms are used again, then they must be installed in their original places.
Note: When removing, record the location of each rocker arm.
2. Remove rocker (1) from cylinder head (2).
Cleaning and inspection
1. View video (1) rocker arms and check the following:
- are there any bald
- whether there are too many scratches or chipping,
- Is the rotation of the roller difficult?
- Examine the area where the contact occurs (2) rocker with valve.
- Inspect the site (3), on which the rocker arm rests on a stationary hydraulic valve clearance compensator.
2. Replace rocker arm if required.
Installation procedure
1. Lubricate the bearing recess liberally (1), video clip (2) and valve cut (3) rocker arms with conventional camshaft/pushrod prelubrication or equivalent.
Attention!
- rocker (1) should be located straight at the end of the valve so that the roller contacts the camshaft cam over its entire width.
- If the rocker arms are used again, then they must be installed in their original places.
2. Install the rocker arm on the end of the valve and on the stationary hydraulic valve clearance compensator. The end of the rocker with a round head should be on the compensator, and the flat end should be on the end of the valve.
3. Clean the journals and camshaft bearings with a clean, lint- and thread-free cloth.
4. Install the camshafts in their places. See «Camshaft» in this section.
