22 Assembly Instructions - Moldboard
Moldboard 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.
Close the slide box by installing the 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"
hex head screw through each mounting hole and secure with a 3/4"-10
top lock nut. Tighten each nut until approximately two threads appear.
CAUTION: Do not over tighten hex head nuts! Binding may
prohibit the pivot beam from moving properly on the plow.
3. Hook each EXTENSION SPRING to the 3/4" diameter receiving holes
located on the pivot beam and connect the opposite end of the spring to
their respective SPADE BOLTS. Install the four 5/8"-11 x 6-11/16" spade
bolts through the EXTENSION SPRING MOUNTING ANGLE on the top
rear of the blade. Secure each spade bolt by placing one 5/8" flat washer
on the bolt and thread one 5/8"-11 nylon insert lock nut. Tighten each lock
nut until light appears between the coils of the spring.
4. Install the flexible BLADE GUIDES at the end of each plow wing. Insert
the 5/16"-18 x 1" hex head screw through the holes provided at the top
of the wing reinforcement rib. Tighten all screws using the nylon insert lock
nuts provided.
Congratulations! You have successfully completed the first stage of assembly
for the Blizzard Power Plow Model 810SS. In the next section you will assemble
the A-frame and the components that are attached to it.
