Common fault with these motors I'm afraid.
The only option is to look for a scrap tuntable with the same motor as there are no replacement ones out there that I know of. Suitable donors are BG1800 to 5000 series (from the 1980's), RX, TX, all the later tangential tracking models (3000 to 9500) and the beocenter 2200. You may need to swap the pully depending on the donor deck but these simply pull off.

The use of metaphors should be avoided like the plague. They're like a red rag to a bull to me.
