The assembly procedure for the autogap
accessory is as follows:
Step 1
Place the straight springs (white) over the
armature bosses on the back side of the
armature (Figure 5).
Step 2
Compress the heavy (red) spring on each drive pin
by sliding the detent spring towards the head of
the pin (Figure 6).
Step 3
Insert the assembled drive pins through the
armature (entering from segmented side), through
the straight (white) springs, and into the armature
hub.
Note: Apply Grade "AA" Loctite ® Sealant
on the pin threads (Figure 7).
Step 4
Tighten the pins until the shoulders of the
pins are against the face of the hub. Since the
threads are class No. 3 fit, the pins may seem
to bind.
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.
