C. Assembling the Armature
1. The spline drive armature unit is shipped
with the armature, splined armature
adapter, and autogap already assembled.
The splined hub and capscrew accessory
are shipped as separate parts.
Follow these instructions to assemble the
splined armature assembly and hub:
a. Place the armature-splined adapter
assembly on a flat surface with the
segmented side up.
b. Push the splined hub, with the pilot
diameter down (refer to illustration
drawings) through the autogap spring
and splined armature adapter.

2. A customer may mount the clutch
armature hub to his own pulley, hub, gear,
etc. Refer to the illustration drawings,
"Armature View," for the dimensional
information needed to drill and tap holes
in the customer part.
The splined hub pilot diameter must be
concentric with the splined armature
center of rotation within .020 T.I.R.
3. Mount the armature hub to the customer
supplied pulley, sprocket or hub, using the
capscrew accessory provided. Maintain a
1/32-inch clearance between the armature
adapter and the customer part after the
parts have been assembled.
D. Mounting the Armature Assembly
1. Slide the armature assembly on to
the shaft.
2. If the magnet and magnet hub assembly
have been secured to the shaft 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 automatically be maintained
throughout the life of the unit.
(See Figure 3)
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
improper contact between the brushes
and collector ring.
2. The distance from the centerline of the
shaft to the top of the brushholder should
be 5-3/4". Maintaining this distance will
assure proper spring tension on the
brushes and maximum wear follow-up. A
detailed dimensional drawing is included
with each brushholder.
