Assemble the snap ring into the groove in the

hub, clamping the release spring against the end

of the spline. (Figure 9)

D. Mounting the Armature Assembly

1. (250 and 400 units only) Insert a key in the

keyway of the shaft.

2. Slide the armature assembly onto the shaft.

3. Position the assembly in accordance with

the overall axial dimensions given on the

illustration drawings. For air gap (.015'').

4. Secure the assembly in this position by

alternately tightening the two setscrews in the

hub.

5. The hub will need to be repositioned as wear

occurs with time.
