MOUNTING HYDRAULIC VALVE AND BRACKET
The mounting of hydraulic valve requires use of only T-shaped mounting bracket.
Bracket is positioned on top of frame rail, adjacent to steering orbital.
Holes are marked then drilled, and provided 3/8” bolts are used to fasten mounting bracket to
frame rail.
Raven valve is then attached to mounting bracket using provided bolts. Valve should be
positioned so valve coil stack is pointing in a rearward direction.

To begin installation of hydraulic hose kit, first
disconnect existing pressure hose from steering
orbital and then re-connect to port labeled “P” on
Raven valve.
EF hose connects to “EF” port on Raven valve
and to open “P” port on steering orbital.
Tank hose is disconnected from steer orbital,
then #8 90oelbow and run tee are attached to
orbital as shown in picture. Original tank line is
re-connected to tee.
Raven tank hose is then connected to “T” port on
Raven valve to tee on tank port of steering
orbital.
Right steer hose is disconnected from steering
orbital,then#6 90oelbowand runtee areattached
to orbital as shown in picture. Original right steer
hose is then connected to tee.
Raven right steer hose is then connected to “B”
port on Raven valve, to tee on right steer port of
orbital.
Leftsteerhose is disconnected fromsteer orbital,
then #6 run tee is attached to orbital. Original
left steer hose is re-attached to tee on orbital.
Raven left steer hose is then connected to “A”
port on Raven valve, to tee on left steer port of
orbital.
NOTE: When routing hoses, be sure that hoses
are not obstructing path of clutch pedal when
being depressed.

The SPS is mounted on right side of
machine.
One end is attached to tie rod as shown
in picture, using provided clamps and
mounting tab.
Other end is attached to front axel near
spindle, by welding mounting tab to
machine as shown in picture.
IMPORTANT! On initial startup, be sure
to check SPS stroke by turning wheels
slowly. Do not overextend or
overcompress sensor!

START-UP PROCEDURES
Check S.P.S. stroke length to be sure it is not over compressed or over extended.
Turn steering wheel full left and right to purge system of air.
Set valve timing for a left to right and right to left time of 12 to 13 seconds.
Adjust pressure switch to most responsive setting. For additional information, refer to
Universal kit manual.
Connect wire harness to left and right steering coils, SPS and pressure switch.
Inner coil is right coil and outer coil is left coil. If steering is reversed, switch coil connections
around.
