1. Use a straight-edge to check if the shafts are
aligned with each other. For a more precise
indication of align ment, use a dial indicator.
2. Adjust the position of the motor, reducer, or
other hardware as required to achieve the
correct align ment.
3. To be sure the shafts stay in alignment, drill
holes for tapered dowel pins through the
mounting bases of the motor, reducer, or
other hardware and into the mounting
surfaces. This procedure will ensure that,
after the clutch-coupling has been installed,
the shafts can easily be placed in proper
alignment again by lining up the holes and
secured by inserting the dow el pins.
B. Installing the Conduit Box
Install the conduit box on the field. Instructions for
this procedure can be found with conduit box.

C. Mounting the Field-and-Rotor
Assembly
Flange-Mounted Units
The fields and rotors are shipped separately for
flange-mounted units. On some applications it will
be nec es sary to mount the rotor first, and then
bring the field into position. In other instances, the
field will be mounted first, and then the rotor
(mounted on a shaft) will be inserted into place.
1. Mounting the Field
a. Care must be taken in selecting the
location for mount ing the field assembly.
Pilot diameters are machined on the field
mounting flange to aid in hold ing the field
in the proper position.
b. An appropriate pilot diameter must be
provided on the mounting surface as
well. (Figure 2)

c. The field assembly is then fastened in place
with capscrews and lockwashers. (Figure 3)
d. After the unit is in place the mounting face
and pilot di am e ter must be square and
concentric with the shaft in accordance with
the tolerances listed on the draw ings.
(Fig ure 4)
2. Mounting the Rotor
a. Assemble the rotor to the rotor hub with
capscrews and lockwashers. The rotor is
reversible de pend ing on the side from which
the taperlock bushing must en ter. A pilot
di am e ter is machined on the rotor hub to
assure a proper fit.
b. The rotor hub is mounted on the shaft with
a taper lock bushing. Be sure all parts are
clean and free of dirt, chips, and burrs
before assembling.
c. Insert the bushing into the taper bore.
d. Loosely assemble the two locking screws
be tween the bushing and rotor.
e. Insert the key into the shaft keyway. Prick
punch the end of the keyway to ensure that
the key can not slide out.
