To repair the charge relief valve, remove
the hex-plug, spring and valve cone.
Remove the shims from the counter bore
of the hex-plug. Do not alter these shims
unless new parts are used, in which case
the valve must be re-shimmed to the
proper setting.To re-install, insert the
valve cone, spring and plug, being certain
the shims are in place.

The high-pressure relief valves are car-
120 tridges that are removed by unscrewing
them from the manifold.These valves are
factory set and the three (3) numbers
of the pressure setting are stamped on
the end of the cartridge.These valves are
interchangeable and can be installed in
either side of the manifold, providing the
pressure settings are the same.
