I'm trying to clean this advance unit. It runs the thermometer on Heat Wave. The band of steel that is the "mercury" in the thermometer runs along the white reel, which is kind of a pulley.
I cannot get the reel off. Also, the sprocket won't come off. After removing the hex nuts, I can wiggle it about 1/2" up the spindle, but that's it.
I sure don't want to bend these parts by forcing them off, but I've got to get them off so I can get it all cleaned.
Is there a tool for this? Some pinball mechanic trick that I don't know about?
Thanks!
Mike
