through remaining (4) holes. (Figure 4)

Step 5
Holding the pins in position, place the armature hub
over one armature. NOTE: Make sure that the
straight springs on the armature bosses fit into the
grooves in the armature hub. Drive pins require
application of Grade “AA” Loctite ® ‚ sealant on
threads. (Figure 5)
Figure 5
Step 6
Draw these (4) drive pins up tightly until shoulder of
pin is against face of armature boss (since threads
are class No. 3 fit, pins may seem to bind).
Step 7
Place the armature hub and armature assembled in
step 5 & 6 over the remaining armature. NOTE: Make
sure that the four remaining straight springs on the
armature bosses fit into the grooves in the armature
hub. Drive pins require application of Grade “AA”
Loctite
® ‚ sealant on threads. (Figure 6)

Step 8
Draw drive pins up tightly until shoulder of pin is
against face of armature boss, (since threads are
class No. 3 fit, pins may seem to bind). NOTE:
Rotate tightening of drive pins, tightening each
drive pin a few turns at a time. (Figure 7)

Step 9
Compress one of the armatures and armature hub
together until the armature hub bottoms on the
armature boss. Slide the retainer, on each pin, down
tightly against the armature hub. Turn the assembly
over and repeat this procedure for remaining
armature. NOTE: This position must not be
disturbed during completion of assembly. (Figure 8)

Step 10
Slide the assembly with taperlock bushing over the
shaft. Place the face of the armature approximately
1/32" from the brake magnet face and fix the
taperlock bushing to the shaft.
Step 11
Place the clutch magnet approximately 1/32" from
the armature face, and tighten the taperlock bushing
to the shaft. The unit should then be checked for
concentricity and squareness to the shaft by means
of a dial indicator. The unit should be concentric to
the shaft within .010 T.I.R. and square to the shaft
As in the case of a clutch, the customer may wish to
mount the armature to his pulley, hub, etc. The above
dimensions must be followed for adaptation to the
armature.
1. The chordal dimension must be held for all chords
between pin holes.
2. Sleeve bearings (Oilite Bronze) must be provided
in the holes of pulley or hub with an I.D. of .376
± .001 at the chordal and bolt circle dimensions
shown above.
3. The drive pins must be square with plane of
mounting surface and magnet within .006 T.I.R.
Our standard armature hub may be used for the
mounting of a gear, sprocket or pulley.
