Warner Electric’s UniModule has been designed
to NEMA standards and can be installed with all
standard power transmission drive systems.

Before installing the UniModule to a motor or
reducer, make certain that the UM UniModule
size and NEMA frame dimensions match accord­ing to the following chart.

Install your specific modular combination accord­ing to the installation steps specified in the table.
Use only those steps indicated for each combi­nation.

The 1020 and 1040 UniModules are furnished
with a special hardened key. It is strongly recom­mended that this key be used with the motor
shaft to avoid damage to the shaft and rotor hub.

The size 210 UniModules require an adapter ring
to be mounted to the motor prior to mounting the
1020 or 1040 UniModule. Adapter and mounting
hardware are provided with the UniModule
assembly.

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.

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. Failure to
properly tighten the setscrews may result in
damage to the motor shaft and rotor hub and
will void warranty. (40 to 45 in. lbs. for 180
size, 80 to 85 in. lbs. for 50 and 210 sizes.)

Figure 3

Mounting to a Reducer

The output side of a UniModule may be
mounted directly to a reducer.

A. Align the output shaft and key of the

UniModule with the corresponding shaft hole
and keyway of the reducer. Slide assembly
together, matching pilot diameter on the
UniModule with pilot diameter on the reducer.

B. Bolt the UniModule to the reducer flange. The

four (4) bolts required (3/8 - 16 UNC-2A) are
normally furnished with the reducer. (18 to 22
ft. lbs. for 50 and 180 sizes, 40 to 45 lbs. for
210 size.)

Figure 4

Mounting to a Motor:

1. Replace the existing motor shaft key with the
hardened key provided with the unit. If neces­sary, 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.

Figure 1

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 alternately and securely. (30 to 35 ft.
lbs.)
