PROPER PROCEDURE FOR INSTALLATION AND REMOVAL
OF TAPERLOCK KEYLESS FEEDWHEEL COUPLERS AND
FEEDWHEEL MOTORS
B. Installation Procedure
1. Remove any sharp edges on the coupler bore, the motor shaft, or the feedwheel shaft.
Example: Emery cloth or file for burrs on shafts.
2. Rough up the feedwheel shaft and feedwheel motor shaft horizontally along the axis of the shaft.
3. Clean the coupler bore, motor shaft, and feedwheel shaft with a degreasing solvent.
. Slide the coupler onto the feedwheel shaft until it stops.
. Install the motor with the torque arm installed into the feedwheel shaft.
6. Tighten the coupler locking screws in several stages by using 1/4 turns or 90° in a clockwise or
counter-clockwise direction (not diametrically opposed, like wheel lug nuts) until you reach a
torque of ft.-lbs. (7 Nm).
7. Make 2 more passes torquing the locking screws to 55 ft.-lbs. (74 Nm) after the torque has
been reached.
8. Make 1 more pass torquing the locking screws to 52 ft.-lbs. (71 Nm). No screws should turn at
this point or repeat step 7.
C. Removal Procedure
1. Make sure there are no torque or thrust loads on the coupler, feedwheel shaft, or feedwheel
motor.
2. Loosen the locking screws in several stages by using 1/2 turns, following a clockwise or
counter-clockwise direction, until the coupling can be moved on the shaft.
. Remove the feedwheel motor and then the coupler.
DO NOT
completely remove locking screws before outer collars are disengaged from inner ring. A sudden
release of the outer collars involves high separating forces and could result in permanent injury or death. Be
certain that outer collars are disengaged from inner ring before completely removing locking screws.
WARNING
Never tighten locking screws before shaft installation, as the coupler sleeve bore can be permanently deformed
even at relatively low tightening torques.
