Moldboard & A-Frame Assembly - Blizzard 680LT Assembly & Operation Manual

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" DIA. x 3" CLEVIS PIN through each mount-
ing hole and secure them with one 1/4" DIA. x 1-1/2" COTTER PIN.
Note: Mount the kickstand to the end of the pivot beam (driver's side)
using the 1/2"-13 x 4-1/2" bolt provided. The spring, bushing and lock
nut locate on the inside of the pivot beam. Review the diagram to the
right and on page 22. Upon 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 10-1/2" to
level ground. Tighten both of the 1/2"-13 top lock nuts on the kickstand.
Note: To prevent the kickstand from hitting the ground before the
snowplow cutting edges, causing stress on the kickstand lock pin,
adjust the kickstand foot approximately 1/8" short of level ground.
This procedure will provide clearance for the kickstand when the
snowplow is lowered with the kickstand in the down position.
2. Remove each dust cap from both of the ANGLE CYLINDER ports and
attach one 7/16"-20 x 7/16"-20 MALE O.R.B. CONNECTOR ADAPTER
to each port. Note: All of the hydraulic adapters can be found pack-
aged with the manifold assembly. Reference the torque specifications
table on page 33. Connect one 1/4" x 15" hydraulic hose (P/N 60294)
to the driver's side angle cylinder adapter. Note: The 90˚ end on the
hose connects to the manifold. Connect one 1/4" x 20" hydraulic hose
(P/N 60296) to the passenger's side angle cylinder adapter. Be careful
not to overtighten the hose connections. Route both hoses through
the access holes in A-frame at the A-frame angle cylinder mount
brackets. Both hoses should extend through the triangular openings at
the top of the A-frame.
3. Position each ANGLE CYLINDER with the rod end of the cylinder in
the pivot beam and the base end in the A-frame angle cylinder mount
bracket. Secure each cylinder to the pivot beam and A-frame using
two 3/4" x 3" CLEVIS PINS with 1/4" x 1-1/2" COTTER PINS.
4. Next, remove both of the plastic dust caps from the HYDRAULIC LIFT
CYLINDER ports. Attach one 7/16"-20 x 7/16"-20 MALE O.R.B. CON-
NECTOR ADAPTER to the retract port (rod end) and one 7/16"-20 x
7/16"-20 90˚ O.R.B. ADJUSTABLE ELBOW ADAPTER to the extend
port (base end). Once the adapters have been installed on the cylinder,
connect the rod end hose. The male connector adapter receives a
1/4" x 18" hydraulic hose (P/N 60295).
5. Position the lift cylinder in the channel opening under the A-frame.
Route the 18" rod end hose through the front (closest to the pivot
beam) 2" diameter hole in the A-frame. The lift cylinder base end hole
should align with the holes on either side of the channel. Secure the
lift cylinder to the A-frame using one 5/8" DIA. x 5-3/4" CLEVIS PIN
and one 1/4" x 1-1/2" cotter pin. Use the access hole in the A-frame,
located at the driver's side, to install the clevis pin. The 90˚ adjustable
elbow adapter receives the 1/4" x 10" hydraulic hose (P/N 60293).

The kickstand mounts 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. Adjust the kick-
stand foot approximately 1/8" short of level ground.
This will prevent the kickstand from hitting the
ground before the plow cutting edges. The proper
height of your snowplow mounting points to level
ground should be set at 10-1/2".
