Pin the base of the cylinder between the
center lugs of the lift frame with the 3/4" x 3"
clevis pin. The hydraulic fitting should be on
the right side of the cylinder.
Remove four lift links and the stop plate kit
from the parts box. From the hardware bag
remove two 3/4 inch hex bolts, two 3/4 inch
I.D. shim washers and one 3/4 inch nylon in-
sert lock nut. Also remove the 1/2 inch hex
bolt and upper link spacer bushing.
Identify the RH and LH upper and lower links
by referring to drawing 6585. Assemble the
links with their stop surfaces away from the
lift cylinder.
Remove the 1/2 inch hex bolt and spacer
from between the tabs on the push frame.
Slide the stop plate onto the bolt, as shown
in the drawing, then bolt the two lower links
inside the tabs, with the spacer between the
links.
Assemble the two upper lift links outside
the lugs on the lift frame with a 3/4 inch x
4 1/4 inch hex bolt and nylon insert lock
nut.
Bolt the upper link spacer bushing between
the two upper links with the 1/2 inch hex
bolt and lock nut.
Place the flat washer and spacer bushing
from the stop plate kit onto the remaining
3/4 inch hex bolt, then complete the lift
mechanism assembly by bolting the lift cyl-
inder rod, lower links and two shim washers
between the upper links.

5.
Bolt through the upper set of bottom holes
in the upper links for most vehicles, then
secure the assembly with the 3/4 inch lock
nut from the stop plate kit. Bolting through
the lower set of holes will increase down-
ward plow travel for taller trucks, but reduce
lift height.
Rotate the stop plate up to contact the spac-
er bushing on the lift cylinder bolt. Gently
push back on the upper lift frame tube, then
release to allow the weight of the frame to
lock the stop plate in place.
Before assembling the power unit on the lift
frame, scrape a small amount of paint from
the two mount holes in the lift frame to pro-
vide a good electrical ground for the turn
signals and parking lights.
Mount the power unit on the lift frame with
two 3/8" x 3/4" hex bolts and two 3/8" lock
washers. The plastic reservoir of the power
unit should be to the left side of the plow.
