E. Mounting the Magnet-Hub-Armature
Assembly
This assembly is mounted on the shaft with a
taperlock bushing. All parts must be clean and
free from burrs and chips before assembling.
1. Place the bushing into the hub, and insert the
key. The key is a side-to-side fit and should not
contact the top of the keyway.
2. Insert the locking setscrews loosely into the
bushing, and slide the assembly onto the shaft.
3. Position the assembly to allow a gap of about
1/32-inch between the brake magnet and
armature faces. (Figure 11)
Once this gap is set, it will be automatically
maintained for the life of the unit.
4. Secure the assembly in this position on the
shaft by alternately tightening each setscrew.
During the tightening process the bushing
should be tapped lightly to make certain it
seats-in properly.
F. Assembling the Clutch Armature
The spline drive armatures are shipped with a
built-in autogap spring accessory. This device
automatically maintains a gap of about 1/32-inch
between the armature and magnet faces for the
life of the unit.

These units are shipped with the armature,
splined armature adapter, and autogap already
assembled. The splined hub, retainer ring, and
bushing are shipped as separate parts.
Follow these instructions to assemble the
armature and splined hub.
Step 1
Place the armature-splined adapter assembly on
a flat surface with the segmented side up. Push
the splined hub, with the retainer ring groove
down, through the autogap spring and splined
armature adapter. (Figure 12)
