Release the Compression Coupling
Follow these steps to release the compression coupling prior to dismounting the
motor.
1. Use a 6 mm hex bit to loosen the compression coupling in hole A .
2. Loosen the compression coupling one complete revolution beyond
finger-tight to be sure the coupling releases from the machine shaft.
3. Secure the black cap screw in hole A by tightening it to 3.4 N•m (2.5 ft•lb).
Remove the Motor From the Machine
Follow these steps to remove the motor and to cover the opening before storing it.
1. Remove the fastener from each of the four mounting holes in the motor
faceplate.
2. Slide the motor off the machine shaft.
Cover the Mounting End of the Motor
Seal the opening in the motor by performing the following steps.
1. Insert the protective paper sleeving around the rotor.
2. Cover the opening at the mounting end of the motor with the cardboard
cover that came with the motor.
TIP
Notches in the motor-mounting surfaces provide a means to gently pry the motor loose
from the machine.
A flat-bladed pry bar may be used to loosen the motor.
ATTENTION
Magnetized material within the motor is exposed whenever the protective cover is
removed and before the motor is mounted.
Accidental entry of foreign material can harm motor performance.
Always cover the mounting end of motor immediately after removing the motor or its
protective cover. This will greatly reduce the possibility of magnetic or non-magnetic
particles accidentally entering the motor.
