I have a Venture dish mover that is frozen solid. The motor works fine and is in good condition, but the jackscrew part is locked up. The Venture website says that it is repairable with common tools, but it looks to me like I have to take a pin out of the coupler that connects the motor to the tube. There appears to be holes in the tube that are to be used to remove the pin, but the shaft is frozen in a position where the pin does not line up with the holes. I tried flooding it with penetrating oil but it won't budge. The tube doesn't appear to be crushed or damaged anywhere. Assuming I can get into the tube does anyone know what I might find in there? I would like to be able to use the old dish mover if possible, but if it's going to take major repairs I might get a new one. I'm hoping someone has worked on these and knows what probably needs to be done to it.
