For 3-Piece Coupled Input Reducers
(Reference Figure 1)
Prepare the motor by checking the motor shaft extension for dirt
or damage. Remove any anti-rust coating that may be on the
shaft. Apply a thin even coating of anti-seize compound to the
entire motor shaft.
Insert the coupling key into the motor shaft keyway. Slip the motor
coupling half onto the motor shaft and locate it a distance "x" from
the motor shaft end. Refer to Figure 1 for definition of distance
"x". Refer to the Table 3 for values of "x" for each motor.
Tighten the motor coupling half setscrew to the correct torque
value listed below.
Check that the reducer coupling half, with its key in place, is
mounted on the reducer input shaft inside the C-face adapter.
Make sure this coupling half is mounted on the reducer shaft such
that the shaft extends the complete length of the coupling bore.
Insert the coupling spider properly into the coupling jaws.
The Dodge Quantis MSM C-Face reducer should be firmly
anchored to prevent sliding as the motor is mounted. The motor
should be rotated on its axis so the motor flange holes line up with
the C-Face adapter holes. Check to be sure the motor conduit
box, grease fittings and condensations drains (where fitted) will
be oriented as needed by the reducer mounting position.
Hoist motor level and in line with reducer input shaft. For EZ
Kleen Quantis reducers with 180TC or larger NEMA input, install
the o-ring provided onto the motor pilot to seal the input assembly
from water ingress.
Align the motor coupling half such that its jaws are aligned with
the gaps between the spider and the reducer coupling half
jaws. Push the motor into place. Motor flange to C-face adapter
clearances are tight and good alignment is essential.
Insert and tighten the motor retaining bolts Tighten to the correct
torque value listed in Table 3.

For Clamp Collar Input Reducers
(Reference Figure 2)
Prepare the motor by checking the motor shaft extension for dirt
or damage. Use solvent to remove all traces of anti-rust coating
that may be on the shaft.
Check the input bore for dirt or damage. Clean the bore with
solvent to remove all traces of oil or anti-rust coating.
For NEMA motors ONLY: A special long, tall motor key is
provided with the Quantis unit.
1.
Discard the motor key and replace it with the special key
provided. DO NOT USE THE MOTOR KEY.
2.
If the special key does not fit snugly in the motor shaft keyway,
prepare the key for assembly by nicking its bottom in a couple
of spots. A chisel may be used to accomplish this. This must
be done on a work surface away from the Quantis unit and
the motor. This nicking should widen the key bottom and
cause it to fit snugly in the motor keyway. Refer to Figure 5 for
definition of key bottom.
3.
Install the key in the motor shaft keyway by lightly tapping it in
place with a rubber mallet.
4.
Locate the key so that it sits flat in the motor shaft keyway.
The key will probably extend beyond the end of the motor
shaft. This is okay. The key MUST NOT sit tilted in the keyway.
A tilted key can occur when a motor shaft has a sled runner
keyway, Refer to Figure 5.
5.
Mark the clamp collar with a fine tipped marker on both sides
of the setscrew to indicate where the center of the set screw
is located. Run a line down both sides of the clamp collar that
line up with the line previously created.
6.
Remove the socket head screw and set screw from the clamp
collar and apply Loctite 243 thread locker. Reinstall the screws
into the clamp collar. Install the clamp collar onto the reducer
input shaft and line up the mark previously made on the clamp
collar with the center of the keyway in the shaft. If the clamp
collar rotates freely, tighten the clamping screw slightly to
keep it from rotating during assembly. Make sure the marked
line is pointing to the center of the keyway.
The Dodge Quantis MSM C-Face reducer should be firmly
anchored to prevent sliding as the motor is mounted. The motor
should be rotated on its axis so the motor flange holes line up with
the C-Face adapter holes. Check to be sure the motor conduit
box, grease fittings and condensate drains (where fitted) will be
oriented as needed by the reducer mounting position.
Hoist motor level and in line with reducer input shaft. For EZ
Kleen Quantis reducers with 180TC or larger NEMA input, install
the o-ring provided onto the motor pilot to seal the input assembly
from water ingress.
Align the motor shaft with the gear reducer input bore making
sure that the motor shaft keyway is in line with the input bore key.
Push the motor into place. Motor shaft to input bore clearances
are tight and good alignment is essential.
Insert and tighten the motor retaining bolts. Tighten to the correct
torque value listed in Table 3.
