90˚ Adjustable Elbow O.R.B.Adapter
Moldboard & A-Frame Assembly
1. Begin the moldboard assembly by positioning the PIVOT BEAM and
A-FRAME near the connecting points at the rear of the blade between
the two center support ribs. Position the pivot beam between the two
support ribs until the connecting points on the beam align with those
on the plow. Insert one 3/4"-10 x 3" (2" shank) hex head cap screw
through each mounting hole and secure with a 3/4"-10 top lock nut.
Tighten each nut until it is snug with the pivot beam.
CAUTION: Do not over tighten hex head nuts! Binding may
prohibit the pivot beam from moving properly on the plow.
Note:To aid in the remaining installation, rotate the spring loaded kick-
stand clockwise until it locks into place. Adjust the foot on the stand
arm so the height of the A-frame, at its mount points, is 12-1/2" to
level ground (See the diagram to the right).Tighten both of the 1/2"-13
top lock nuts on the kickstand.
2. Position each ANGLE CYLINDER with the rod end of the cylinder
in the pivot beam and the hydraulic hose port facing away from the
A-frame. Secure the cylinder to the pivot beam with one 3/4" x 4-1/2"
CLEVIS PIN and one 1/4" x 1-1/2" HAMMERLOCK COTTER PIN.
Note: The hammerlock cotter pin will “lock” itself into place once the
head of the pin is struck. It is not necessary to bend the pin further
upon installation. Extend each cylinder rod until the cylinder base
mounting hole aligns with the hole on the A-frame angle cylinder
bracket. At this point, insert another clevis pin and secure it with a
cotter pin. Repeat the same installation for the opposite angle cylinder.
3. Remove each dust cap from both of the hydraulic angle cylinder ports
and attach one 9/16"-18 x 9/16"-18 90˚ ADJUSTABLE ELBOW O.R.B.
ADAPTER to each port. Note: All of the hydraulic adapters can be
found packaged with the manifold assembly. Reference the table on
page 33 for proper torque specifications. Each adapter should be
angled toward the top of the moldboard.Connect the 3/8" x 24" hydraulic
hose, labeled #1, to the driver’s side angle cylinder adapter. Attach the
3/8" x 24" hydraulic hose, identified by a #2, to the passenger’s side
angle cylinder adapter. Be careful not to overtighten the hose con-
nections. Route both hoses over the top of each angle cylinder.
4. Next, remove both of the plastic dust caps from the HYDRAULIC
LIFT CYLINDER ports. Attach one 7/16"-20 x 7/16"-20 45˚ ADJUST-
ABLE ELBOW O.R.B. ADAPTER to the driver’s side port and one
7/16"-20 x 7/16"-20 MALE O.R.B. CONNECTOR ADAPTER to the
passenger’s side port. Once the adapters have been installed on the
cylinder, connect the HYDRAULIC HOSES. Note: Position the fittings
in the cylinder port such that the hoses install directly in the center of
the A-frame access holes.A hose installed too close to the edge of the
opening may work itself free with the operation of the lift cylinder and/
or movement of the plow. The 45˚ adapter on the driver’s side of the
cylinder receives a 1/4" x 17" hose identified by a label containing the
number 3. Connect the 45˚ angle on the hose to the hydraulic adapter
on the cylinder. The male connector adapter on the passenger’s side
of the cylinder receives a 1/4" x 15" hose identified by a label contain-
ing the number 4. Tighten the 45˚ end of the hose to the hydraulic
The kickstand is mounted to the side of the pivot
beam with one 1/2"-13 x 4-1/2" hex cap screw
and top lock nut. To pivot the kickstand, simply
pull the spring loaded leg out and rotate it until
the pin locks into place.The kickstand also has
an adjustable foot that can be moved to accom-
modate varying vehicle heights. The proper
height of your snowplow mounting points to level
ground should be set at 12-1/2".
