Removal (528e)
- Remove cylinder head from engine. Remove camshaft sprocket. Adjust valve clearance of all valves to maximum value. Remove front and rear rubber plugs on either side of rocker shafts.
- Remove thrust plate from rocker shafts (at front of head). Remove spring clips from rockers. Turn camshaft so valves of cylinder No. 6 overlap.
- Rotate camshaft 1/4 turn against normal direction of rotation, and at the same time push rockers for cylinders 3 and 4 to the rear. Push all remaining rockers toward the front of the head.
- When the camshaft is clear of the rockers, both rocker shafts can be removed. Be sure to keep all rockers in order for later installation in their original locations.
