Figure 17: Belt Replacement & Adjustment

If an adjustment is required:

1.  Loosen the four hex nuts on the motor assembly.
2.  Move the motor assembly until the belt is tight.
3.  Tighten the hex nuts and recheck the belt tension by exerting pressure on the belt.

The belt should deflect approximately 3/8-inch (9.5 mm).

Reassembly:

1. In reverse order, reinstall the bearing housing. Once it is securely in place, remove

the tie wraps/cord.

2.  Secure the wiring to ensure no interference during rotation.
3.  Reinstall the subplatform and platform.
4.  Recalibrate speed (

see Section 7.9

).
