INSTALLATION INSTRUCTIONS
Note: The following instructions cover assembly of
Moldboard, Sector and A-Frame. Refer to separate
instructions for installation of plow mounting and hydraulic
system.
A. Liberally coat Pivot Pins (27) with chassis lubricant.
B. Attach Sector (24) to Moldboard (1) with Pivot Pins (27)
(grease fitting facing outward) and insert Cotter Pin.
Grease Pivot Pin using grease fitting.
C. Attach Eye Bolts (28) to Moldboard (1) and trip Springs
(26) to Sector (24), making certain locknuts (28) are
positioned as shown in Figure 1.
D. Make certain each Eye Bolt (28) is in a vertical position
as shown in figure 1 so that the Eye Bolt (28) and Trip
Spring (26) hinge properly when moldboard trips.
Note: Proper tension is attained when Trip Spring (26) coils
just begin to separate and then tightening top locknut four
additional turns. Tighten bottom Locknut (20530) to secure
Eyebolt in position. Install Eyebolt caps (07031) over
exposed threads. See Figure 1.
RIB
E. Attach A-Frame to Sector (24) as shown in Figure 2.
IMPORTANT: Install King Bolt (29) from bottom so that
locknut is on top.
