Mounting to a C-Face Motor
1. A hardened key is provided with the mounting
hardware for UniModules. Insert this key onto the
motor shaft. It is recommended to stake the end
of the motor shaft keyway to keep the key from
moving out during operation.
2. Align the keyway in the bore of the UniModule
to the key in the motor shaft and slide the unit
onto the motor shaft. The normal alignment of
the module to the motor will be with the wire
exit/conduit box in the upright (12 o’clock)
position as shown in Figure 1.
Do not hammer or force the
module into position. To do so may damage
bearings or cause the friction faces to shift out of
alignment.
Figure 1
If anti-fretting lubricant is used on
the motor shaft for future ease of removal, ensure
that any excess is wiped off before unit assembly
to avoid lubricant contaminating the clutch or
brake friction faces.
3. Secure the UniModule to the motor with the four
(4) long mounting tie-bolts provided. Tighten the
four (4) bolts alternately to ensure even alignment
of the module. Tighten them to 30-35 foot
pounds.
Do not tighten the two (2) clutch
rotor set screws to the shaft before tightening
the four (4) module tie-bolts. This could cause
a preload on the pilot bearing resulting in
premature bearing failure.
4. Next secure the clutch rotor and fan assembly to
the motor shaft by tightening the two (2) setscrew
as follows:
a. There are two (2) access slots on either side
of the UniModule. A long Allen wrench can be
used to tighten the two setscrews (90° apart)
which secure the clutch rotor and fan assembly
to the motor shaft.
b. Alternately align each setscrew with one of the
access slots by rotating the clutch rotor and
fan assembly through one of the side vents
with a small screw driver taking care not to
damage the fan. (Figure 2a)

c. Using a torque wrench and long Allen socket,
tighten the two (2) setscrews to: (Figure 2b)
• Size 50: 80-85 inch pounds
(Requires 5/32 inch Allen wrench)
• Size 100 or 180: 40-45 inch pounds
(Requires 1/8 inch Allen wrench)
