PROCEDURE FOR INSTALLATION AND REMOVAL OF
J.B. COUPLERS AND TAPERED FEEDWHEEL MOTORS
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.
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.
13. 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
Loctite 243 on the threads and then tighten nut
flush with top of pin.

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.

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 Loctite 263 on
the threads.
6. Tighten to the correct torque, 461 Nm (340 ft. -lbs.)
for “DT” motor, 339-407 Nm (250-300 ft.-lbs.) for
“RE/TG” motor, & 203-230 Nm (150-170 ft.-lbs.)
for “RS/TE” motor.
7. Slightly tap with a hammer on the coupler face to
ensure proper seating.
