Mounting to a C-Face Motor
1. A hardened key is provided with the
mounting hardware for FBC UniModules.
Insert this key onto the motor shaft
(staking the key is necessary).
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 2.
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 2
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 FBC 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.
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 3a)

c. Using a torque wrench and long Allen
socket, tighten the two (2) setscrews
to: (Figure 3b)
