(key 23) to push the groove valve (key 22) out of
the body (key 21), then complete disassembly.

the replacement O-rings before installing them in
the groove valve and retainer.
4. Install the groove valve (key 22) into the same

the retainer into the opposite side of the body, and
tighten until both are secure.
5. When all maintenance is complete, refer to
