STUB SHAFT CONNECTION
1. Purchase a zero backlash flexible shaft coupler that
accommodates the diameter of the Stub Shaft ( Item
8) on one end and the dancer arm pivot shaft on the
other end (See Figures 4 and 9).
2. Slide the shaft coupler onto the dancer arm pivot
shaft, inserting the shaft no further than half the
thickness of the coupler clamp; then, tighten the
clamp around the shaft (See Figure 4).
3. Slide the Stub Shaft (Item 8) into the shaft coupler,
inserting the Stub Shaft no further than half the
thickness of the coupler clamp; then, tighten the
clamp around the Stub Shaft (See Figure 4).
4. Position the Dancer Arm in its mid-travel position.
5. The orientation of the Dancer Position Sensor (Item
1) must be as shown in order to match the mid
output of the Dancer Position Sensor to the mid
travel position of the dancer arm (See Figure 5).
6. Attach Dancer Position Sensor (Item 1) to the
Bracket (Item 2) with the Long Pan Head Screws
(Item 3, Flat Washers (Item 4), Lock Washers (Item
5), and Nuts (Item 6) (See Figure 4).
7. Align Dancer Position Sensor (Item 1) with the
center of the slots in the Bracket (Item 2) and then
hand tighten just enough to prevent sensor from
moving during Steps 8 and 9 (See Figure 4).
8. With the dancer arm held firmly in its mid travel
position, slide the Dancer Position Sensor (Item 1)
over the Stub Shaft (Item 8) while carefully aligning
the key with the shaft’s key way (See Figure 4).
9. Slide the Dancer Position Sensor (Item 1) onto the
Stub Shaft (Item 8); then, measure the distance from
the bottom of the Bracket (Item 2) to the machine’s
side frame. Fabricate a spacer block to make up the
distance between the Bracket and the machine’s
side frame (See Figure 4).
10. Repeat Steps 8 and 9 with the spacer block in place
on the machine’s side frame and mark the location
for the bracket’s mounting holes.
11. Remove the Dancer Position Sensor(Item 1)and Brac-
ket (Item 2); then, drill and tap two 8-32 threaded
holes centered within the marks drawn in Step 10.
12. Slide the Dancer Position Sensor (Item 1) onto the Stub
Shaft (Item 8) while carefully aligning the key and key way;
then, using two customer supplied 8-32 screws and lock
washers, secure the Bracket (Item 2) to the customer
supplied spacer block (See Figure 4).
