D. Assembling the Brake Armature and
Magnet Hub
Assemble the armature to the magnet hub with the
autogap mounting accessory.
The autogap accessory 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 6)
Note: The 1225 unit is mounted with four drive
pins instead of three as shown in the pictures;
however, the assembly procedure is the same for
either case.
Step 1
Place straight springs (white) over armature bosses
on back side of armature. (Figure 7)
C. Assembling the Clutch Magnet and
Magnet Hub
1. Insert the lead wires through the rubber termi-
nal caps and into 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)
3. Secure the lead wires to the magnet terminals
with screws and lockwashers.
4. Pull the rubber caps over the terminals.
