Step 4 Tighten drive pins until shoulders of pins
are against face of armature bosses. Since
threads are class No. 3 fit, pins may seem
to bind.
Step 5 Compress the retainer rings against the
armature hub (or customer-supplied part),
and check to see that the part is held
tightly to the armature bosses. Note: This
po si tion must not be disturbed during
completion of as sem bly. (Figure 10)
D. Mounting the Armature Assembly
1. Slide the armature assembly onto the shaft.
2. If the field-and-rotor assembly has been
secured to the shaft or a machine member
first, then adjust the armature’s position to
allow approximately 1/32-inch between the
two faces.
Once this 1/32-inch gap has been set, it will
be au to mat i cal ly maintained throughout the
life of the unit. (Figure 11)
3. Secure the assembly in this position on the
shaft.
