Part Number 981-0501-66 for “DT” Motor
Part Number 981-0501-61 for “RE” and “RS” Motor
MAINTENANCE SECTION
CAUTION Always wear proper safety equipment and take caution with tapered pin
when attempting to remove. The use of this tool will assist in the removal of the tapered pin in the feedwheel
coupler. Lubricate end of bolt and threads with grease. Position the press tool so that it cradles the coupler, with
the large end of the tapered pin at the side opposite the press bolt. You may want to remove yoke springs to get
easier access to coupler. Set the tool as described and hand tighten press bolt to snug tool against coupler. Make
sure press bolt is set on small end of tapered pin, and that pin will go through hole in tool without interference.
Use of a 1/2” impact wrench is recommended. Run impact on bolt to start pin removal, then usually a good hit
with hammer on the end of bolt will knock out the pin. You may have to run impact on bolt and hit with hammer
a few times to remove pin. Do not spend excessive time trying to remove the pin and coupler. If problems occur
during pin and coupler removal, contact your nearest dealer or Bandit Industries.
Removal if tapered pin is equipped with a nut to assist in pin removal: Use a hand
wrench and turn the tapered pin nut clockwise, half a turn and then hit the small end of
the tapered pin with a hammer and punch. Repeat this process until pin is removed.
B. Installation Procedure
1. Remove any sharp edges on the coupler bores or the motor shaft.
Example: Emery cloth or file for burrs on keyways or shafts.
2. Clean the coupler bores and motor shaft with a degreasing solvent.
3. Install the correct key in the feedwheel motor shaft.
4. Slide the coupler onto the motor shaft, making sure that the two mate tightly.
Example: The coupler does not rock or slop on the shaft.
5. Install the self locking nut with Loc-Tite 271 on the threads.
6. Tighten to the correct torque, 340 ft.-lbs. (461 Nm) for “DT” motor, 250-300 ft.-lbs. (339-407 Nm)
for “RE” motor, & 150-170 ft.-lbs. (203-230 Nm) for “RS” motor.
7. Slightly tap with a hammer on the coupler face to insure proper seating.
8. Retorque self locking nut.
9. Deburr and degrease the feedwheel shaft.
10. Install the motor and coupler assembly onto the feedwheel shaft.
11. Install the correct tapered pin through the coupler and feedwheel shaft.
12. If coupler pin is threaded and is equipped with a nut, make sure the nut is flush with top of pin.
1. Hammer the pin into the coupler to secure the coupler and feedwheel shaft. If the pin is
threaded and has a nut do not hammer the pin directly, use a piece of wood as a buffer.
14. If the tapered pin is equipped with a nut, put Loc-Tite 241 on the threads and then tighten nut
flush with top of pin.
