3. Secure the lead wires to the magnet terminals
with screws and lockwashers.
4. Pull the rubber caps over the terminals.
D. Assembling the Brake Armature and
Magnet Hub
Assemble the armature to the magnet hub with
the autogap mounting accessory.
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 efficiency
throughout the life of the unit.
The assembly procedure for the autogap
accessory is as follows (Figure 6):
4. Use a dial indicator to check the unit for con-
centricity and squareness to the shaft. The unit
should be concentric within .010 T.I.R. and
square within .006 T.I.R. (Figure 3)
C. Assembling the Clutch Magnet and
Magnet Hub
1. Insert the lead wires through the rubber
terminal caps and onto the collector ring. The
shorter wire goes into the hole in the front of
the ring (the side that will be mounted to the
magnet). The longer wire goes through the ring
and into the hole in the back.
Press the bullet-type connectors firmly into
place. (Figure 4)
2. Mount the magnet to the magnet hub using
capscrews and lockwashers. (Figure 5)
