f. After the disk shoe position is properly adjusted
place washers on the shoe stem - above the plow
frame and below the retaining lynch pin - to remove
all up and down movement of the disk shoe in the
frame. Failure to do so will result in excessive wear
of the holes in the frame or bending of the shoe
stem.
IMPORTANT:
Snap lynch pin ring over so that it
contacts the pin. If ring does not contact lynch pin,
rotate the pin and reverse the direction of the ring. If
the ring does not contact the pin it is not locked and
could fall out.
g. Lower the plow to the ground and check adjustment.
Repeat adjustment if required.
Trip Spring Adjustment
NOTE: The trip springs are factory installed and
adjusted, but adjustment should be checked during plow
set-up and installation.
Springs are properly adjusted when two or more coils
allow a 0.010" feeler gauge to just pass between the
separated coils. (A 3 x 5" post card is approximately the
same thickness.)
If re-adjustment is required:
1. Raise the plow to the full UP position and support the
blade with suitable blocking.
2. Turn the vehicle OFF, apply the parking brake and
remove the ignition key.
3. Check to make sure that the springs are installed as
illustrated. (See Figure 1-16).
Figure 1-16
4. Loosen the lower jam nut on each eyebolt. (See
Figure 1-16).
5. Tighten the upper retaining nut until a 0.010" feeler
gauge can pass between two or more coils on each
spring.
6. Hold the upper nut and tighten the lower nut securely
on each spring.
NUTS
0.015 (1/64") GAP
MAXIMUM
CAUTION
• Do not overtighten springs. If more than 0.015"
(1/64") gap appears between coil with Plow at
rest, damage could occur to equipment during
plowing.
