Line up the keyways and slide the gear box
assembly onto the drive shaft. To aid in
aligning the keyways, turn the input shaft of the
primary gear box.

Removing Gear Box Assembly
1. Disconnect the power and ground wires from
the conveyor motor. Remove the motor from
the primary gear box.
2. Loosen the fasteners on each of the idler shaft
bearings located at the front of the spreader on
both sides of the sill.
3. Loosen the jam nuts on the take-up bolts. Back
off the bolts enough to allow the idler shaft to
slide back evenly. This will allow the conveyor
chain to slacken.
4. At the secondary gear box (lower) remove
the black plastic cover exposing the end of
the drive shaft. Remove the 1" retaining ring
(e-clip) from the end of the drive shaft.
5. Remove the four fasteners that mount the gear
box bracket to the electric power group mount.
6. Pull the gear box assembly out. The drive shaft
will remain in place. You may need to lightly
tap on the end of the shaft to get it started. Be
careful not to damage the end of the shaft.
5. Install the motor to the gear box assembly
using four 3/8"-16 x 3/4" cap screws with lock
washers.
6. Connect the power and ground wires to the motor.
7. Tighten the take-up bolts evenly from side to
side until the conveyor chain is visible through
the chain tension port. You should be able to
lift up the chain 1"
–
3" at approximately
20"
–
24" from the rear of the spreader.
NOTE: Adjusting the conveyor chain too tight
will increase amperage draw.
8. Once the correct chain tension has been
achieved, tighten the four bearing mounting bolts.
9. Run the spreader to verify that the conveyor
chain tension and alignment, playing close
attention to the conveyor chain direction. If
the conveyor is turning in the wrong direction,
swap the power and ground wires to change
the direction.
