7.8 Motor Removal and Reinstallation
1. Disconnect the power source to the drive motor (e.g., lockout/tagout the motor disconnect).
2. Disconnect the motor wiring from the motor.
3. Attach required lifting device to the motor. Do not put any tension on the pump motor at this
time.
4. Remove the four Motor Attachment Bolts from the motor (refer to Figure 24). Some European
motors will have eight bolts
5. Open the access panel by removing the three access panel screws to expose the coupling.
The coupling is an interlocking jaw design and uses an elastomeric spider between the two
coupling halves. The upper half of the coupling remains on the motor shaft and the lower
half stays on the worm gear shaft.
6. Lift the motor from the mounting adaptor.
7. If the motor is to be replaced, position the “old” motor so that the upper coupling is accessible.
8. Loosen the upper coupling setscrew to allow removal of the upper coupling half, taking care to
not lose the shaft key.
9. Install the upper coupling half on the shaft of the replacement motor, ensuring that the shaft key
is in place.
10. Align the end of the shaft flush with the inner surface of the coupling and tighten the setscrew.
11. Reinstall the motor by reversing the steps above.
