PLOW ASSEMBLY
PLOW ASSEMBLY
1. Place moldboard face down on cardboard
or other padding that will prevent scratches
in the paint.
Remove two side markers and four ship-
ping straps from the ends of the moldboard.
Save the bolts and nuts for reinstalling
markers later.
Remove the two 5/8” bolts through the cen-
ter ribs on the back of the moldboard, and
save for reinstallation later.
Remove the three hinge pins from the back
of the moldboard by driving out one spring
pin, and save for reinstallation.
Additional compression springs are includ-
ed with 8 1/2’ moldboards. Remove springs
and set aside for reassembly.
2. Open the frame crate and set aside the
power unit box, headlamp boxes and parts
box for later assembly.
Carefully lift the frame assembly by wrap-
ping straps or padded chains around both
ends of the 2 1/2” square tube at the rear of
the frame. Attach the frame assembly to the
moldboard by lining up the three bushings
on the frame with the three sets of bushings
on the moldboard.
Apply commercially available anti-seize lu-
bricant (not supplied) to the hinge pins to
prevent future corrosion, and reinstall the
hinge pins through the bushings. Secure
the hinge pins with spring pins.
Remove 3/4” lock nuts from the back of
each compression spring. Align each pull-
rod bushing with the upper set of holes in
the moldboard ribs and reinstall 5/8” bolts
and lock nuts. Tighten lock nuts only until
snug against ribs.
Assemble 3/4” lock nuts back onto pullrods
and tighten until compression springs mea-
sure 13” long. Do not overtighten springs.
GENERAL INFORMATION
