Valve Spring: Service and Repair

Valve Spring





Special Tool(s)

Removal and Installation
1. Remove the roller followers.

2. NOTE: If air pressure has forced the piston to the bottom of the cylinder, any loss of air pressure will allow the valve(s) to fall into the cylinder. A rubber band, tape or string wrapped around the end of the valve stem will prevent this from happening.

Pressurize the cylinder using compressed air.





3. Using the special tool, remove the key, retainer, and valve spring.
4. To install, reverse the removal procedure.
