MANIFOLD ASSEMBLY & ELECTRICAL INSTALLATION – SNOWPLOW SIDE
NOTE: The snowplow side electrical harness and
connect/disconnect switch must be installed
before the manifold is secured.
1. Remove the nut, washer and alignment ring
from the POWER HITCH™ connect/disconnect
toggle switch and insert it through the back of
the mounting bracket on the A-frame. Align the
notches on the switch and bracket. Replace the
alignment ring, washer and nut and tighten until
the switch is fi rmly in place. Attach the connector
on the snowplow harness to the switch.
NOTE: Use caution when connecting, switches
can break if done forcefully.

2. Attach the connector on the harness to the
connector on the coil harness.
3. Assemble the manifold. The manifold, pump
and coil harness have been connected at the
factory; however, the manifold contains several
components that you will need to install prior to
securing the assembly to the A-frame. Each of the
hose ports on the manifold is covered with a dust
cap. Remove the cap and install the appropriate
fi tting in its respective port. Tighten fi ttings and
hoses according to the torque chart. Rest the
manifold assembly between the mount brackets
on the A-frame.
NOTE: The arrow shown on the manifold
illustration indicates the direction the
90° adapters should be positioned to receive the
hydraulic hoses.
Lit. No. B64118, Rev. 03
NOTE: The fl ow control knob will need to be
removed to install the fi tting into Port #3.
NOTE: DO NOT let any foreign objects enter
into the open ports. The valves can become
contaminated and greatly hinder the snowplow's
performance. Torque to proper specifi cations.
NOTE: All ports are identifi ed by a stamped
number on the manifold. The numbers also
identify the hydraulic functions, which can be
referenced on the label under the hydraulic pump
and manifold cover.
4. Connect the red power wire from the snowplow
harness to the pump motor terminal stud.
Hardware provided on pump.
NOTE: The red power wire contains an end ring
terminal that is too large for the pump motor
stud. Remove this terminal and replace it with the
1/4" end ring terminal on the pump motor terminal
stud.
5. Align the mount holes in the pump with the holes
in the bracket, located on the A-frame. Secure
with 3/8" x 1-1/4" cap screw, 3/8" lock washer and
3/8" fl at washer through the top mount hole in the
bracket and into the pump. Insert 3/8" x 1-1/4" cap
screw, 3/8" lock washer and 3/8" fl at washer
through the bottom mount hole in the bracket and
into the pump. This is also the ground location for
the snowplow harness.
NOTE: When installing the manifold between
the mount brackets on the A-frame, hold the
manifold at the sides of the block. Never handle
the manifold by the coils. Doing so can cause a
solenoid cartridge to bend, causing the cartridge
to stick when activated.
