Note: The equipment covered by this service
manual must be installed in accordance with
these instructions. Failure to do so may damage
the equipment and void the warranty.
Mounting to a Motor
Step 1
Note: The 1020 Unimodule is furnished with a
special hardened key. It is strongly recommend-
ed that this key be used with the motor shaft to
avoid damage to the shaft and rotor hub.
Note: Size 210 Unimodules require an adapter
ring to be mounted to the motor prior to mount-
ing the 1020 Unimodule. Adapter and mounting
hardware are provided with each Unimodule
assembly.
Note: Before mounting, check the motor shaft
for endplay. If the shaft can be moved axially
.030" or more, excessive thrust may occur
between the rotor and field. The
motor should be replaced unless the endplay
can be reduced.
Note: If the optional fan accessory is being
used, it should be installed prior to mounting the
Unimodule to a motor or reducer. Follow the
instructions provided with the fan
accessory.
Replace the existing motor shaft key with the
hardened key provided with the unit. If neces-
sary, prick punch the keyway of the motor shaft
to keep the key from moving in the keyway.
Slide the module assembly onto the motor shaft.
(See Figure 1) Align the key in the motor shaft
with the keyway in the rotor hub.
Do not use force. If the UniModule does
not slide on freely, polish the motor shaft
sufficiently to achieve a slip fit.
Step 2
The housing is provided with vent holes which
are normally placed in the down position. Rotate
the assembly to where the vent holes are toward
the bottom and insert the four long capscrews
(provided) through the mounting holes in the
housing and into the motor face. Tighten alter-
nately and securely. (30 to 35 ft. lbs.)

Step 3
The access hole for the Allen wrench to tighten
the rotor setscrews is shown in Figure 3. Rotate
the clutch rotor as necessary to insert the
wrench into the setscrews. Tighten both screws
alternately and securely. (40 to 45 in. lbs. for 180
size, 80 to 85 in. lbs. for 50 and 210 sizes.)
