Manifold Assembly Components
1. The System Relief Valves are cartridges that
can be removed from the manifold (using 1
3/8" wrench) for inspection or replacement.
These valves are interchangeable in either
side of the manifold, providing the pressure
settings are the same. The first two (2) digits
of the pressure setting are stamped on the
end of the valve.
The relief valves are factory set and should
not be disassembled further.
When replacing, torque the cartridge to 30-70 ft. lbs.
2. The Shuttle Valve can be removed for
inspection by removing the two (2) hex plugs
(using 1" wrench) and sliding out the springs,
spacers, and spool.
These parts are
interchangeable and can be installed from
either side. When assembling be certain the
spacers are placed between the spool and
springs. Torque the hex plugs to 60-100 ft.
The spool and manifold are matched and
cannot be replaced separately.
3. To inspect or replace the Charge Relief Valve,
remove the hex plug (use 1" wrench) and the
spring and poppet. Remove the shims from
the counter bore of the plug. Do not alter
these shims unless new parts are used, in
which case adjusting the valve setting, by
shimming, is necessary. To install, insert the
poppet, spring, shims and plug. Be certain
the shims are in place in the plug. Torque to
60-100 ft. lbs.
