Warner Electric PCBC-500 Clutch_Brake Coupling - Manual (Page 6)

Note: This position must not be disturbed during
completion of as sem bly. (Figure 11)
D. Mounting the Armature Assembly
1. Slide the armature assembly onto the shaft.
Keep adjustment in Step 5 (Figure 11) from
moving.
2. If the magnet and magnet hub assembly
has been secured to the shaft first, then adjust
the armature's position to allow approximately
1/32" between the two faces. (Figure 12)
Once this 1/32" gap has been set, it will be
automatically maintained throughout the life of
the unit.
3. Secure the assembly in this position on the
shaft.
E. Mounting the Brushholder
1. The brushholder is mounted on a bracket which
must be furnished by the customer.
The bracket must be firmly secured to
prevent vibration which could cause
im proper contact between the brushes and col-
lector ring.
2. The distance from the centerline of the shaft to
the top of the brushholder should be 4".
Maintaining this dis tance will assure proper
spring tension on the brushes and maximum
wear follow-up. A detailed dimensional
drawing is included with each brushholder.
Step 1 Place straight springs over armature
bosses on back side of armature (Figure 8).
Step 2 Compress conical spring against retainer ring
by sliding detent spring towards head of pin.
(All 3 pins.) (Figure 9)
Step 3 Insert assembled drive pins through
(customer-supplied part (Figure 5) through the
straight springs, and into the threaded arma-
ture bosses. Apply grade "AA" Loctite Sealant
on drive pin threads. (Figure 10)
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 arma-
ture hub (or customer-supplied part), and
check to see that the part is held
tightly to the armature bosses.
