How to replace Cottrell QuiXspinz?

You pretty much have to replace the entire ratchet box. Unless things have changed that's the only way Cottrell sells those parts. It's a really ####ty design, the ratchet heads actually just bolt onto the tube, but once they pinch the tube for the strap anchors, you can no longer access the back side.

 

My independent shop replaced some ratchet boxes for me a few years ago. My quick spins were not bad just the boxes were. I can’t give you exact details because I didn’t watch the entire process, but they cut them out with a torch (I think the stop ring you referenced) and welded them back in to the new boxes they built.

 

They can be cut out. Cut that inner ring off. Cut the idler that holds the strap and you can pull the whole tube out.. or you can just ordered the new modular style and put it in
