MOUNTING INSTRUCTIONS FOR AC-1820A
STEP 1.
Place one inside upper mounting bracket, (Fig. 1, Item 1, Part No. 200536-19), on side
of the dump box rub rail with the bot- tom edge of the bracket even with the bottom edge of the
rub rail. Measure 2 1/2" from the back of the dump box to the center of the 1" hole in bracket, X,
and clamp bracket in place. Drill three 1/2" holes in the dump box to match the holes in the
bracket. Repeat this process for the other side of the dump box. Using the 1/2" x2 1/2* bolts in
the shipping kit, insert bolt from the inside of the rub rail outward. Attach the bracket to the
dump box with a lock washer and nut. Measure the outside distance between both brackets,
keeping this distance approximately 1/4" greater than the inside distance between the end panels
of the cross conveyor. The brackets may need to be spaced out evenly on both sides to attain the
proper distance. Before tightening down the inside brackets, place a flat washer on each bolt and
attach the outside bracket, (Fig. 1, Item 2, Part No. 200536-18), with a lock washer and nut.
Insert the 1" pin x 2 1/4" long, Part No. 220343- 05, through the hole in the brackets and tighten
the inside nut, then the outside nut. Measure the distance from the center of the pin to the ground,
Y.
STEP 2.
Raise the dump box to the top position and measure the distance from the center of the
pin to the ground, (Fig. 2, Z). Determine the angle of the dump box that is half-way between
