Form No. 63551 September 1,1999
IMPORTANT: Read instructions before assembling.
Bolts should be finger tight until instructed to tighten.
Use standard methods and practices when attaching
the snowplow.
1. Lay blade face down on cardboard on the floor.
Assemble the quadrant to the blade with the
quadrant lugs straddling the center ribs. Secure
with two 5/8" x 2-1/2" bolts and locknuts. DO NOT
bend lugs by overtightening nuts.
2. Thread one 5/8" nut halfway down on each of the
two eyebolts. Hook a spring into the hole at the top
of each center rib. Hook an eyebolt to the other
end of each spring. Push the threaded end of each
eyebolt through the holes in the spring lugs on the
quadrant and install a locknut behind the lug.
ASSEMBLY INSTRUCTIONS
Assembling A-frame To Quadrant
1. Insert A-frame into the quadrant channel aligning
A-frame noseplate hole with the center 3/4" hole in
the Quadrant channel. Insert a 3/4" x 5-1/4" bolt
from the top and secure with a locknut on the
bottom. DO NOT overtighten—A-frame should
pivot freely.
2. Align stop bushing with 1/2" holes in quadrant
plates. Secure using a 1/2" x 5-1/2" bolt and
locknut.
3. Use a 3/8” x 1-1/4” grade 5 bolt with 3/8" SAE flat
washer to attach end link of chain to hole in flat bar
on A-frame and secure with a locknut. Attach chain
to side of flat bar towards wide end of A-frame.
(See Figure 2.)
CAUTION
Servicing the trip springs without special tools
and knowledge could result in personal injury.
See your authorized WESTERN®outlet for
service.
CAUTION
Over tightening springs will not increase blade
trip force and can damage the springs.
Adjust trip spring tension by tightening locknut
while preventing eyebolt rotation by holding across
flats using an adjustable wrench. Tighten only until
coils begin to separate. (Instruction sheet should
pass between second and third coils.) Lock in
place by tightening the locknut securely against the
lug while preventing the eyebolt from turning.
4. Insert rod end of each Hydra-Turn®ram into
quadrant channel. Align rod holes with 3/4" holes in
quadrant and insert 3/4" x 4-3/8" grade 5 rivet.
5. Attach base end of each ram (pipe plug facing out)
to the side of A-frame with a 3/4" x 3-1/4" rivet.
Place two 3/4" washers under each ram base
inside A-frame channel.
Insert all rivets from the top and secure with cotter
pins.
CAUTION
See your WESTERN®outlet for application
recommendations.

To avoid personal injury, follow steps in
