Check valve
included on return port
Bypass Valve
—Remove the cap to
access a bypass needle valve. This
valve is shipped from the factory
closed.
The only case when valve
should be open is when running in
series with other hydraulic motors.
Depending on your tractor and exact
hydraulic plumbing scenario your
pump may turn very slowly when it
should stop. To stop the pump
completely, open the bypass valve
slightly.
To adjust the Bypass Needle Valve,
first loosen the lock nut. Do not
overtighten the needle valve.
Pump Rotation Check Valve
A check valve is included on the outlet port of the hydraulic valve. This prevents the pump from running
in the wrong direction. If ran in the wrong direction, liquid will be pumped, however the hydraulic valve
will not be able to control the flow. The check valve can be identified by the Part Number 1108R stamped
on it and a flow direction arrow.

Troubleshooting Tip:
To check coil, an ohmmeter
placed on the two pins should
show 7
-
9 ohms.
Manual Override
-
Push down
and turn 1/2 turn CCW to lift the
valve for manual override to
check for proper hydraulic
operation.
Override will
completely open valve, so
limit tractor hydraulic flow to
valve.
(May need to clean packed dirt
to allow movement of override
knob.)
Push down and turn 1/2 turn
CW to return to operating
position.

Installation
Overview
Hydraulic oil under extremely high pressure. Do not use hand or any other
skin to check for or to stop hydraulic leaks. Be sure pressure is relieved
before loosening hydraulic fittings. Replace worn hoses immediately. Seek
medical care immediately if hydraulic oil is shot into the eye or the skin.
How it Works with Power Beyond Hydraulics
This valve is designed to work with power beyond hydraulics. This configuration will not require a standard
tractor remote hydraulic valve. The load sense port and hose described next will typically not be needed if
other hydraulic ports are in use. If the load sense is needed, do this: First, remove the load sense plug and
install a #6 male boss x #6 JIC adapter fitting, SureFire PN 161

-
6MB
-
6MJ. Then run a
3/8”
or
1/4”
hydraulic hose back to the tractor. This hose will connect to the load sense port on the tractor. The load
sense line will signal the tractor hydraulic system to supply the flow needed by the pump to meet your
application rate. The SureFire valve has an internal load sense check valve, which is required for power
beyond hydraulics.. The bypass valve (see above) must be closed to use power beyond hydraulics or else
an unlimited amount of oil will be continuously circulated.
