10. 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 stretch
wrap. Remove the wrap and install the appropriate
fi tting in its respective port. Tighten fi ttings and
hoses per torque chart.

NOTE: The arrows shown on the manifold
illustration indicate the direction in which the
90° adapters should be positioned to receive the
hydraulic hoses.
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.
11. Align the mount holes in the pump with the holes
in the hinged bracket, located on the A-frame.

NOTE: Before mounting the pump, angle the
hinged bracket as needed and tighten the bracket
hardware to lock it in place.
Secure with 3/8" x 3/4" cap screw and 3/8" fl at
washer through the top mount hole in the bracket
and into the pump. Insert 3/8" x 1-3/4" threaded
stud with 3/8" locknut through the bottom mount
hole in the bracket and into the pump. The
threaded stud should bottom out in the pump.
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.
NOTE: A medium-strength threadlocking
CV4
compound should be used on both of the pump
mount fasteners.
12. Connect the hydraulic hoses to their respective
adapters on the manifold. Hose PN B60091
or B60223 Ports #1 and #2, Hose PN B60273
Port #3, Hose PN B60274 Port #4, Hose
PN 49501 Ports #7 and #10, Hose PN 49501
Ports #8 and #9. Tighten hoses per torque chart.
NOTE: All hoses, except #1 and #2 (angle
cylinders) should be routed through the triangular
openings in the A-frame. Position these hoses
over the A-frame angle and to their respective
manifold ports.
NOTE: The hoses that operate the retract
functions (rod) of the cylinders are closest to the
base of each cylinder. The hoses that operate
the extend functions (base) of the cylinders are
closest to the rod of each cylinder.
