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).

Step 6

Compress the retainers against the armature hub and
check to see that the armature hub is held tightly to
the armature bosses.

NOTE: 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 the face of the armature
approximately 1/32" from the magnet face and secure
the taper lock 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.
