COUPLING, CONVEYOR DRIVE
FOR ALL 1100 MODELS
This coupling has a plastic or rubber sleeve connecting two metal drive ends.
The metal drive end on the conveyor side is secured by a ball plunger screw,
This is not a set screw and should never be overtightened.
PROCEDURE FOR ADJUSTING DRIVE COUPLING:
1. Place one metal end on conveyor shaft.
2. Install ball plunger and adjust so the spring loaded ball will drop into the dimple on the flat of the conveyor drive
shaft. To test, apply pressure on metal end towards the conveyor. The ball detent should pop up out of the
dimple and coupling end will slide back to conveyor frame.
3. Place other drive end on motor shaft,
4. Push conveyor frame to front side of oven conveyor opening.
5. Adjust the metal drive end on conveyor shaft so ball detent is in the dimple.
6. Lift conveyor drive side slightly and place sleeve on conveyor side metal drive end.
7. Adjust motor side coupling drive end so sleeve is now held in place between the drive ends and tighten set
screw on motor side firmly.
To remove conveyor, simply grasp the coupling sleeve and pull towards conveyor.
The sleeve and drive end will slide towards the conveyor and separate from the motor
drive.
