5.2.2 Multi Turn Encoder Remounting
Step 1
Slide the encoder spur assembly (#17-2) into housing thru housing controls area bore and down over the multi turn
encoder shaft pinion. Align spur assembly bottom plate to top encoder ball bearing (#1-5), the dowel pin (#17-1) while
also aligning the spur assembly big gear to the encoder shaft pinion.
NOTE: for the 20 turn assembly the big spur gear slots must be aligned with the holes in the top and bottom plates to
insert the two (#17-3) screws. Figure 5.7 for orientation view.
Insert the two screws (#17-3) and tighten.

Step 2
Place spacers (#17-4) (QX-1 &2 only) in place in-between the spur assembly bottom plate and the housing lower pads,
Note that this step can be done before step 1. Insert screws (#17-5) and tighten.
Step 3
Slide the encoder assembly into housing and down over encoder shaft (#2) on multi turn spur assembly aligning the
rotor (#2) of the encoder to the encoder shaft OD, flats and encoder standoff pin to the top spur assembly alignment
hole (See Figure 5.3) for reference.
