3. The field assembly is then fastened in place
with capscrews and lockwashers. (Figure 3)
4. Once the unit is in place, it must be square
and con cen tric with the shaft in accordance
with the tol er anc es listed on the drawings.
(Figure 4)
5. The rotor is mounted on the shaft with a
taperlock bushing. Insert the bushing
into the tapered bore.
6. Loosely assemble the two locking screws
between the bushing and the rotor.
7. Insert the key into the shaft keyway, and slide
the rotor assembly over the key and on to the
shaft.
8. Adjust the rotor’s position to achieve the over-
all axial dimension “L” (page 34) when the
bushing is se cured.
9. Secure the assembly in this position by
alternately tightening the two locking screws.

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.
In either case, the rotor and field must be
positioned in accordance with the overall axial
dimension from the face of the rotor to the back of
the field flange as shown on the illustration drawings
(dimension “L,” page 34). Hold ing this dimension will
assure the proper axial clearance between the field
and the rotor.
1. Care must be taken in selecting the location
for mount ing the field assembly. Pilot diame-
ters are ma chined on the field mounting flange
to aid in holding the field in the proper posi-
tion.
2. An appropriate pilot diameter must be
provided on the mounting surface as well.
