Assem. Instructions - Moldboard & A-frame
Feed each group of hoses (four per side) through
the 1-1/2" diameter holes in the pivot beam and
up through the A-frame openings. Positioning
the hoses through the pivot beam supports the
hoses while the snowplow is in use and prevents
them from dragging on the ground.
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.
CAUTION: The hoses inside of the slide box are installed such
that they move laterally with the action of each wing. To avoid
damaging the hose connections and the wing and slide box
cylinders, pull approximately one foot of each hose grouping
toward the center of the moldboard. Verify that there is approx-
imately 12" of “slack” for each hose grouping. Reposition both
12" lengths back into the slide box – the hoses are now at a
safe travel distance for operation.
The slide box is closed by two SLIDE BOX ACCESS PLATES. Rest each
grouping of hoses in the opening of the plates and position the “lip” of
each plate in the bottom, inside edge of both slide box openings. Fasten
each plate with two 1/4"-20 x 3/4" hex cap screws.
2.
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 3-1/2"
hex head 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 kickstand
arm so the height of the A-frame, at its mount points, is 12-1/2" to level
ground (See diagram on page 8). 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 one 3/4"-10 x 5" hex 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 one 3/4"-10 x 5" hex cap screw through the
aligned holes and secure the screw with one 3/4" 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. Hand tighten each adapter until
snug, then torque approximately 1-1/2 to 2-1/2 flats. Reference the table
on page 5 for proper torque specifications.
Angle each adapter toward the
top of the moldboard and tighten approximately 1-1/2 flats. 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 connections. Route both hoses over the top of each angle cylinder.
