Disassembly & Reassembly
- Remove rings from sleeve with a small knife. Mount worm end of worm and valve sleeve assembly in a soft-jawed vise. Install a mandrell tool (T75L-3517-A1) over the sleeve. Install rings one at a time with the aid of a driver tool (T75L-3517-A2).
- Rapidly push down on pusher tool to force ring down ramp and into fourth groove of valve sleeve. Repeat three more times, each time adding spacers (Tool T75L-3517-A3) under mandrell tool to line up next groove.
- After all sleeve rings are installed, install sizing tool (T75L-3517-A4) carefully over valve sleeve rings. Be sure rings are not bent over as tube is slid over them. Remove sizing tool and check condition of rings. They must turn freely.
