Removal and Installation
1. If servicing the RH cylinder valve train components, remove the RH valve cover.
2. If servicing the LH cylinder valve train components, remove the LH valve cover.
3. Position the piston of the cylinder being serviced at the bottom of the stroke.
4. Install the special tool between the valve spring coils to protect the valve stem seal from damage.
5. CAUTION: The camshaft roller followers must be installed in their original locations. Record the camshaft roller follower locations.
Failure to follow these instructions may result in engine damage.
NOTE: Do not allow the valve keepers to fall off the valve or the valve may drop into the cylinder. If a valve drops into the cylinder, the cylinder
head must be removed.
NOTE: It may be necessary to push the valve down while compressing the spring.
Use the special tool to compress the valve spring and remove the camshaft roller follower.
