It might just be that you’re over tightening it though.
I had to fiddle a bit to get my pulley centered as well.
It didn’t need as much force as I thought it would.
I’ve just fitted a kegel pulley from the EU group buy. There was a group buy with similar items in the US I think the files were from junior potato.
It is excellent, but possibly along the same lines as the one you got.
Thanks for the replies. I finger tightened the bolts and tried throwing it backwards on my truck to allow it center up better. Seems to have helped quite a bit. Think I’m gonna loc-tite these bolts in though.
