1. Drive the vehicle, with snow plow mounted, onto a
smooth, level surface. Park the vehicle, move the plow
wings until the wings are in the scoop position on each
side and lower the plow to the ground.
2. Turn ignition switch OFF and apply the emergency
brake. Turn hand-held controller off.
3. Inspect both float limiter screws and be sure that the
hex head of the screws are not contacting the wear plate
underneath the hex head of the screw. If necessary,
adjust each screw upward so that the screw head is not
contacting the wear plate when the pivot tubes are
vertical.
NOTE: After disk shoe adjustment is completed, the float
limiter adjustment must be made. See "Float Limiter
Adjustment" on page 22.
4. Place a level against the front of the wing pivot tubes
and pull or push the top of the center section until the
level indicates that the pivot tubes are vertical (Not tipped
either forward or rearward.
5. Determine whether the center disk shoe or the center
wearstrip is off the ground and measure the amount that
it is off the ground. (See Figure 2-16).
NOTE: Wing shoes must not be holding wear strips off
the ground.
Figure 2-16
NOTE: Gap may be measured by sliding shims or wash-
ers between the ground and/or the center disk shoe or
the center wearstrip, then measuring the shim/washer
stack. The center disk shoe will need to be adjusted until
the disk shoe and center wearstrip both contact the
ground at the same time.
If the center disk shoe was off the ground - washers
must be ADDED below the disk shoe mounting tube.
If the center wearstrip was off the ground - washers
must be REMOVED from below the disk shoe mounting
tube.
IMPORTANT:
If washers must be added, add one
washer LESS than the amount the disk shoe was off
the ground. If washers must be removed, remove one
washer MORE than the amount the wearstrip was off
the ground.
6. Raise plow and place suitable blocking under the
plow to allow at least eight inches (8") of clearance from
the bottom of the center disk shoe to the ground.
7. Lower plow onto blocking.
8. Adjust center disk shoe assembly by removing the
disk shoe mounting pin and adding or subtracting
washers on the top or bottom of the disk shoe mounting
bracket as required according to measurements taken in
step #4.
9. After the center disk shoe position is properly
adjusted, place washers on the disk shoe stem - above
the disk shoe mounting bracket, and below the retaining
pin - to remove all up and down movement of the disk
shoe in the bracket. Failure to do this will result in
excessive wear of the holes in the disk shoe mounting
bracket and will also result in bending the disk shoe stem.
10. After the center disk shoe adjustment is completed,
lower the plow to the ground. If this disk shoe adjustment
is correct, the center disk shoe and the center wearstrip
will both be on the ground and the wing tubes will be
vertical (Recheck the wing tubes with a level). If wing
tubes are not vertical, repeat steps #3 to #9 until wing
tubes are vertical.
NOTE: If assembling and mounting a snow plow for the
first time, the adjustment of the center disk shoe can be
done with just the center section mounted on the vehicle,
prior to assembling the wings onto the center section of
the plow.
11. With each wing extended straight out to each side,
measure the amount the wing shoes are off the ground,
or if they are on the ground, measure the amount that the
wearstrip is off the ground (measured in front of the d
isk
s
hoe bracket).
12. Raise plow and place suitable blocking under the
plow to allow at least six inches (6") of clearance from the
bottom of the wing disk shoes to the ground.
