NOTE: A NEMA 182/184 TC Frame is required to mate
with the gear reducer. If the pump is purchased without
a motor, you must order a kit to mate with the gear
reducer. See T
ABLE
5.
1. Thoroughly clean the input shaft and motor shaft,
removing any debris. This ensures proper clearance
and fit for the coupler.
NOTE: Do not reuse old keys or setscrews. Use only the
parts supplied with the coupler.
2. See F
IG
. 8. Assemble the key (20) in the input shaft
(105) keyway. Assemble the two setscrews (31) in
the coupler (28), ensuring that they do not encroach
on the keyway or the input shaft bore of the coupler.
3. Slide the coupler into the gear reducer so the key
and input shaft mate with the coupler. Slide on until
coupler bottoms out on the tapered step of the shaft.
4. Tighten setscrews to 66-78 in-lb (7.4-8.8 N•m).
Apply antiseize lubricant (LPS
®
-04110 or equiva-
lent) to bore of coupling.
NOTE: When installing an IEC 112M/B5 or 100L/B5
Frame electric motor, ensure that the motor adapter
(MA) and screws (MS) are in place before mounting the
motor on the gear reducer. Torque screws to 40-45 ft-lb
(54-61 N•m). See F
IG
. 10.
NOTE: A faint clicking may be heard while the motor is
running. This is normal and is due to necessary clear-
ances between the coupler (28), motor shaft, and motor
key. If the intensity increases significantly over time, it
could indicate the coupler is wearing and should be
replaced.
Do not open the gear reducer. Opening the
gear reducer voids the warranty. The gear reducer is
not field serviceable beyond the maintenance recom-
mended in this manual.

NOTE: All kits include the 0.62 in. (15.7 mm) key
(120376). Some kits include an additional motor shaft
key. Measure the length of the motor keyway to
determine the correct key length. Key length should
be at least 90% of keyway length.
NOTICE
Ensure that neither the input key (20) or the end of the
coupler (28) motor shaft bore extend past the end of
the input shaft (105). This could cause the motor shaft
to bottom out on the coupler, causing excessive heat
and bearing damage.
NOTICE
When installing the electric motor, always ensure that
the motor shaft key cannot move out of position. If the
key works loose it could cause excessive heat and
equipment damage.
