Compress the heavy (red) spring on each drive pin
by sliding detent spring towards head of pin.
(Figure 8)
Step 3
Insert assembled drive pins through armature
(entering from segmented side), through straight
(white) springs, and into magnet hub. (Figure 9)
Note: Apply Grade "AA" Loctite® Sealant on
pin threads.
Step 4
Tighten pins until shoulders of pins are against
face of hub. Since threads are class No. 3 fit, pins
may seem to bind.
Straight springs must not get
caught under shoulders of drive pins.
Step 5
Check to see that the armature is completely
compressed against the face of the hub.

Step 6

against the armature face. (Figure 10)
Note: This position must not be disturbed during
completion of assembly.
E. Mounting the Magnet-Hub-Armature
Assembly
This assembly is mounted on the shaft with a
taperlock bushing. All parts must be clean and free
from burrs and chips before assembling.
1. Place the bushing into the hub, and insert the
key. The key is a side-to-side fit and should not
contact the top of the keyway.
2. Insert the locking setscrews loosely into the
bushing, and slide the assembly onto the shaft.
