6. Install the large unload pulley (13) onto the flighting shaft using a 1/4” x 2-1/2” square key (14) (see
for available pulley sizes, depending on desired flighting speed). DO NOT tighten set screws
(not shown).
7. Place the belts (15) on the pulleys (7, 13).
8. Align the two pulleys using a straight edge, ensuring that the large unload pulley is flush against the bearing
lock collar.
9. To tension the belts, adjust the motor mount hinge pin (17) to the hole position that will keep the motor
level and fully tension the belts. The hole selected will depend on the pulley diameters and the motor size
(height between motor shaft and motor legs). Rotate the 5/8” threaded rod (19) until the belts have
approximately 1/4" – 1/2" (6 mm – 13 mm) deflection when a 5 lb (22 N) force is applied at the belt center.
Note
The correct operating tension is the lowest tension at which the belts will not slip under peak load
conditions.
10. Tighten all the set screws on the pulleys.
Note
Once all bolts and set screws are tightened, re-check alignment. Proper alignment will prolong belt
life.
11. Once belt alignment is complete, move the backplate (3) to a position where the motor shaft will cause the
least interference. Tighten the backplate bolts (4) securely.
12. Close and lock the plastic pulley guard (16) using the quick-clip.
