Assembling the Armature and Hub
Assemble the armature to the armature hub with
the autogap mounting accessory. Follow these
instructions to assemble the armature and hub.
1. Apply Loctite ® #242 (or #290, or equivalent) to
drive pin threads. Insert the drive pin into the hub
and tighten until the shoulder of the pin is against
the hub. (Figure 1)
2. Assemble the red
spring over the drive
pin. The smaller
diameter of the
spring should be
against the hub.
3. Place the detent
retainer over the
pin. The cupped-
out portion should
be against the
spring. (Figure 2)
4. Place the detent ring
on the pin and press it into the recessed portion
of the detent retainer. (Figure 2)
5. Slide the detent ring
towards the hub to
allow about 1/2"
between the ring
and head of the pin.
(Figure 3)
6. Slide the armature on
the pins. The face of
the armature should
be towards the hub.

Drive Pin
armature. (Figure 4)
8. Compress the spring
to allow the retainer
ring to be snapped
into the groove at the
head of the pin.
Mounting the Armature-Hub Assembly
(See Figure 5)
1. Insert taperlock bushing into the bore of the hub.
2. Loosely insert the locking setscrews and slide the
assembly on to the shaft.
3. Position the assembly to allow a gap of 1/16"
between the faces of the armature and magnet.
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".
Once this gap is set it
will be automatically
maintained throughout
the life of the unit.
6. Use capscrews and
lockwashers to bolt
adapter cover.
