HYDRAULIC CROSS CONVEYOR
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

6
fully raised and fully lowered. Lower the dump box to this degree and mount the spreader to the
truck. Be sure the spreader is level and measure the distance between the lower mounting hole
and the ground, (Fig. 3, D).
STEP 3. In the shipping kit there are 4 brackets approximately 24" long with a 1" dia. hole in
each, use the difference in the Y measurement and the Z measurement, (Fig. 3, Y-Z), to locate
the distance for drilling the second 1" dia. hole from the existing hole. If more than an inch of the
bracket is left beyond the hole, cut the extra material away to prevent any type of interference.
STEP 4. Using two of the four modified brackets, (Fig.3, Item 4, Part No. 200536-21). place one
on each side of the lower mounting plate on the front of the spreader and insert a 1" pin x 3"
long, Part No. 220343-06, through the hole securing it with a hitch pin, Part No.
FM-00518. Repeat this process for the other lower mounting plate.
CAUTION: END GATE MAY CAUSE SEVERE DAMAGE WHEN RAISING DUMP
BOX WITH MATERIAL IN SPREADER.
STEP 5. There are 2 brackets in the shipping kit approximately 15" long with a 1" dia. hole in
each, Part No. 200536-20. Place one bracket against the truck frame and align it between the two
brackets on the lower mounting plate of the spreader. Spacers of some type may need to be used
to line up the brackets properly. Refer to Fig. 3, Item 3, and Fig. 4 for further details. Insert a 1"
pinx3" long through the hole and secure it with a hitch pin.
STEP 6. Move the shorter bracket along the frame until the distance between the hole you
drilled and the ground is the same as the measurement "D" in Fig. 3. Tack weld the bracket to the
truck frame and repeat this process for the other side. If you have the spreader leveled on
removable stands, clear all objects from underneath the spreader. Check to see if the spreader is
going to remain level by raising and lowering the dump box. If the spreader remains adequately
level, attach the brackets more securely (solid weld or bolts). If the spreader does not remain
adequately level, then break loose the tacks and raise or lower the bracket to correct for the
direction in which the spreader is unlevel. With the dump box at the fully raised position, the

7
spreader may be unlevel, but this will not cause any damage since there is little material in the
dump box at this position
STEP 7. Completely lower the dump box, then raise it until there is just over 2" of space
between the front of the dump box and the subframe. Weld stop block, (Fig. 4, Item 5, Part No.
200536-22) securely to horizontal leveling arms. The block should be in contact with the vertical
leveling bracket when the dump box is completely. lowered. This will prevent the spreader from
tilting, which could cause serious damage!
STEP8. Connect all hydraulic hoses and fittings, then check conveyor direction. If rotation is
opposite of desired direction, switch hose connections.
STEP 9. Attach rubber Hap in shipping kit to the back edge of the dump box. The flap should
hang inside of the spreader when the dump box is raised.
STEP 10. If asphalt is to be conveyed, spray the rubber flap and conveyor belt lightly with fuel
oil. Do not spray oil on the drive roller lagging!
AC-1820A SPECIFICATIONS
MOTOR: The fluid pressure into the conveyor motor should be approximately 1500 psi.
The recommended flow for the conveyor motor is 20 gpm.
BELT: The conveyor belt supplied is heat and petroleum resistant. lt can withstand
temperatures of up to 350° F. The belt is also equipped with a molded guide underneath
to align the conveyor belt with the grooves in the pulleys. If the belt tends to travel
toward one side, then the adjustment bolt on that side may need to be tightened. The belt
tension should be checked regularly.
PRECAUTIONS BEFORE SPREADER OPERATION
Material should be loaded into the spreader by raising the dump box at intervals. Filling the
spreader continuously could cause overflow and damage the conveyor motor. Spill guards are
provided in the shipping kit to prevent material from spilling over the end panels of the spreader.
These guards may need to be modified for clearance with the feed gate opening. When operation
of the spreader is complete. we do recommend that you run the conveyor until all of the material
is removed. This will prevent accumulation in undesired areas. If material builds-up between the
tailgate and the spreader, the tailgate could apply severe pressure on the spreader causing some
damage.
WARNING!
Use extreme caution around moving parts. Keep hands and loose clothing away from spreader
while in operation.
