Anyone ever have the worm come loose on its shaft. This is the all nation tower drive with gears not chains. I noticed that one of the wheels was not turning and sliding on the rail. It turns out that the worm has some how came loose on its shaft and the shaft is spinning in the worm bore. I assume that the worm was a press fit on the shaft. I am thinking that I will Loctite the worm to the shaft but first I have to get the tower assembly apart. The tower is assembled by forming the extension of the shaft bearings into holes in the side plates and forming them over like riveting (anyone who has an all nation drive will know what I am referring to). Question now is how to disassemble the tower. I am thinking I will drill the extensions out until the side plates can be removed. After the worm is loctited to its shaft, I am thinking that I will solder the side plates back on.
