6. Slide drive pulley onto motor shaft. Insert a 1/4” x 1-1/2” square key and tighten set
screws.
Note:
The correct pulley size (based on a 1750 rpm motor) is as follows:
7. Place electric motor onto mount
and secure. Do not tighten.
8. Place belts on pulleys and apply
slight tension. Align the 2 pulleys
(use a straight edge). Tighten
motor bolts and pulley set
screws.
Once all bolts and set screws are
tightened, re-check alignment.
Proper alignment will prolong belt
life.
9. Adjust the plastic pulley guard
backplate to make sure it will not
rub on the electric motor shaft.
Tighten backplate mount bolts/
nuts securely.
10. Close and lock the plastic pulley
guard into place (Figure 3.35).
