Replacement Sprocket for the ADOR1 or ADOR2

If you ever have to replace the sprocket, this item is a direct replacement for ADOR1 and ADOR2 units back to 2012.  NOTE:  the sprocket rarely needs to be replaced, so if you aren't sure that the sprocket is causing a problem, then call us for troubleshooting. 

Remember when tightening the setscrew on the motor shaft, the screw MUST bear down on the FLAT part of the motor shaft.  See the video link below if you aren't sure.

If your sprocket has become loose on the hub, that is something that you can fix yourself easily.  Just remove the sprocket and re-clinch the divots with a hammer and center-punch or big nail, against a solid surface.  An anvil, vice, or concrete floor will suffice for the solid surface.

Or maybe the sprocket is merely loose on the motor shaft and if so, tighten the set screw as shown in this video.
