Moldboard & A-frame Assembly 05
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. Feed the right and left group of HYDRAULIC
HOSES protruding from the SLIDE BOX through the 1-1/2" diameter
rubber grommet openings in the front face of the pivot beam.
2. Position the pivot beam between the two support ribs until the con-
necting 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.
3. 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 a 3/4"-10 x 5-1/2"
hex head cap screw and one 3/4"-10 top lock nut. 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 a 3/4"-10 x 5" hex
cap screw and secure it with one 3/4"-10 top lock nut. Repeat the same
installation for the opposite angle cylinder.
4. 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 20 for proper torque specifications. Each adapter should be
angled toward the top of the moldboard. Connect one 3/8" x 26"
hydraulic hose, labeled with a part number (P/N 60223), to both the
driver’s side and passenger’s side angle cylinder adapters. Be careful
not to overtighten the hose connections. Route both hoses over the top
of each angle cylinder.
5. 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 part number (P/N
60092). Connect the 45˚ angle on the hose to the hydraulic adapter
on the cylinder. The male connector adapter on the passenger’s side
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".
