through straight springs and into threaded holes in
back of armature. Drive pins require application of
Grade “AA” Loctite
® Sealant on threads.
Step 5
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).

check to see that the armature hub is held tightly to the
armature bosses. This position must not be disturbed
during completion of assembly.
Step 7
Slide the armature and armature hub with taperlock
bushing over the shaft. Place armature face
approximately 1/32” from the magnet face and secure
the taperlock bushing to the shaft. This gap will be
automatically maintained throughout the life of the unit.
The unit should 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 within .006 T.I.R.
Failure to follow these instructions
may result in product damage, equipment damage,
and serious or fatal injury to personnel.
