Setting the Autogap for a Heavy Duty Clutch Coupling
or Brake in sizes 500 & 650
https://p.widencdn.net/mqwdke/V-0100-WE
The heavy duty units contain spline drive armatures and
hubs . The armatures are shipped with a built-in autogap
spring accessory . This device automatically maintains a
gap of about 1/32” between the armature and magnet
faces for the life of the unit .
Follow these instructions to assemble the armature and
splined hub .
Step 1
Place the splined hub on a flat surface . The extended
portion of the hub, where the set screw holes are lo cat-
ed, should be down .
Step 2
Check the detent ring in the armature assembly to
make sure it is centered evenly around the spline . This
ring moves freely, but it should be centered for easier
as sem bly of the hub .
Step 3
Holding the armature with the segmented side up, press
the armature onto the splined hub . This is most easily
done by applying firm back-and-forth pressure . (Figure

Step 4
Push the assembly up against the retainer ring .

D. Mounting the Armature-Hub Assembly
1 . Slide the armature-hub assembly onto the shaft
until the armature face touches the magnet face .
2 . Move the assembly back to allow a gap of about
1/16” between the two faces .
3 . Secure the armature-hub assembly in this posi-
tion by tightening the two setscrews in the hub .
4 . Check the assembly by pressing the armature
into contact with the magnet face and then
releasing it . The armature should spring back
about 1/32” . This gap will be automatically main-
tained throughout the life of the unit . (Figure 5)
