C. Assembling the Armature and Hub
Assemble the armature to the armature hub with the
autogap mounting accessory. The hub is reversible. The
side on which the armature is mounted will depend on
the direction in which the taperlock
bushing must enter.
The autogap assembly is a double spring device which
allows for automatic armature clearance and adjustment
for wear. The smaller or conical spring pushes the
armature from the magnet face, leaving a gap of about
1/32-inch, while the straight spring automatically follows
up for wear. This combination maintains maximum
performance efficiency throughout the life of the unit.
The assembly procedure for the autogap accessory is as
follows: (Figure 4)
Note: Autogap accessory is shipped pre-assembled.
Step 1 Place straight springs over armature
bosses on backside of armature. (Figure 5)
