Step 6
To set the autogap, slide the detent spring
retainers against the armature face.

Note: This

position must not be disturbed during
completion of the assembly (Figure 8).

D. Mounting the Armature Assembly

The armature and armature hub are 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 into the bushing

and slide the assembly onto the shaft.

3. Place the face of the armature approximately

1/32-inch from the face of the magnet. Once
this gap is set, it will be automatically
maintained throughout the life of the unit.
(See Figure 9.)

4. Securely fasten the armature assembly to the

shaft by alternately tightening each setscrew.
During the tightening process, the bushing
should be tapped lightly to make certain it
seats-in properly.
