F. Clean all contamination and corrosion from the mating flanges.
G. Support the motor and mount it to the adapter.
H. Apply a medium strength thread locking compound such as blue Loctite to the bolt threads according to the
instructions. Install the bolts and tighten them securely.
I. Reconnect the wiring to the motor. Refer to Figure 2 for the motor and options connection diagrams.
5. Removing and Replacing Integral Motors
A. Shut off the power to the motor and post the shutoff with OUT OF SERVICE. Disconnect the wiring to the
motor. Tag each wire as it is disconnected.
B. Support the motor and remove the bolts securing the motor to the gearbox.
NOTE: Most integral motor installations have mounting bolts accessible from the motor exterior. If the
bolts are not visible, unbolt the input flange from the gearbox. Remove four bolts that mount the
motor. Remove and discard the Dubo gaskets from the bolts.
C. Remove the motor from the gearbox.
D. Clean the gasket faces on the motor and gearbox, making sure no cleaning debris enters the gearbox.
E. Check the replacement motor to make sure the motor flange, motor shaft, and motor pinion are identical to the
motor that was removed.
F. Place a new gasket between the gearbox and new motor.
G. Position the motor on the gearbox, making sure the input pinion meshes with the input gear. Rotate the motor
as necessary to align the bolt holes and seat the motor flange. Make sure the gasket remains properly aligned
and seated.
H. Apply a medium strength thread locking compound such as blue Loctite to the bolt threads according to the
instructions. Install the bolts and tighten them securely.
NOTE: If the motor/gearbox installation uses an input flange, mount the input flange to the motor using
four mounting bolts and new Dubo gasket. Tighten the bolts securely.
CAUTION: DO NOT TO MIX TYPES OF OIL.
I. Check the gearbox oil level. If necessary fill the gearbox or add oil to bring the gearbox oil to the correct level.
Check the installation and maintenance manual for your gearbox to find the correct oil for the gearbox.
J. Reconnect the wiring to the motor. Refer to Figure 2 for the motor and options connection diagrams.
6. Handling
and Lifting
A.
Before lifting any motor, disconnect all electrical connections. Tag each wire as it is disconnected.
B. Disconnect the motor from the gearbox. Do not lift the motor while it has other equipment attached to it.
C. If the motor has provisions for a lifting eye, turn in an appropriately sized lifting eye and lock it in place with
the locking nut. Lift the motor by the lifting eye using an appropriate lifting device.
D. If the motor does not have provisions for a lifting eye, seek assistance or use appropriate lifting devices as
necessary.
7. Storage
If the motor is not in service, store it according to the following conditions:
A. Cover the motor and store it in a clean warehouse environment protected from dust and fluids.
B. If the motor has internal heaters, power the heaters during storage if the storage environment is extremely
humid. The heaters will prevent moisture buildup in the motor interior.
C. Before placing the motor in service, visually inspect the motor exterior for evidence of deterioration during
storage. Turn the motor shaft by hand to make sure the shaft turns smoothly and freely.
