Step 7
Assemble the light spring over the pin. The
large diameter of the spring should be against the
armature.
Step 8
Compress the spring to allow the retainer ring to
be snapped into the groove at the head of the pin
(Figure 4).
C. Mounting the Armature-Hub Assembly
1. Insert the taperlock bushing into the bore of the
hub.
2. Loosely insert the locking setscrews and slide
the assembly onto the shaft.
3. Position the assembly to allow a gap of
1/16-inch between the faces of the armature
and magnet (Figure 5)
4. Secure the assembly in this position by
alternately tightening the locking setscrews.
The bushing should be tapped lightly from
time-to-time to make sure it seats-in properly.
5. Set the autogap by pressing the armature into
contact with the friction face and then releasing
the armature. The armature should spring back
approximately 1/32-inch. Once this gap is set it
will be automatically maintained throughout the
life of the unit.
6. Bolt the cover to the adapter using
capscrews and lockwashers (Figure 6).
