3. 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 rotor 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. (See Figure 5)
The assembly procedure for the autogap
accessory is as follows:
Note The 1225 and 1525 units are 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 the straight (white) springs over
the armature bosses on the back
(unsegmented) side of the armature.
(See Figure 6)
Step 2 Compress the heavy (red) spring
against the retainer ring by sliding the
detent spring towards the head of the
pin. (See Figure 7)

Step 3 Insert the assembled drive pins
through the armature (entering from
the segmented side), through the
straight (white) springs, and into the
armature hub or customer-supplied
pulley, sprocket or hub.
Note Apply Grade "AA" Loctite ®
Sealant on the pin threads
(SeeFigure 8).
Step 4 Tighten the pins until the shoulders of
the pins are against the face of the
hub or customer-supplied part.
The straight springs must
not get caught under the
shoulders of the drive pins.
Step 5 Check to see that the armature is
completely compressed against the
face of the hub or customer-supplied
part.
Step 6 To get the autogap, slide the detent
spring retainers against the armature
face.
Note This portion must not be
disturbed during completion of
the assembly. (See Figure 9)
