I have been applying Liquid Wrench penetrating oil to it every day for a week, but I can't get it off. I am using a large pair of locking pliers to try and remove it.
What can I do besides taking it to my LBS and getting them to remove it with their special tools?
The problem with using locking pliers is that you're flexing the ring tighetr against the shaft as you try to turn it. If you have a piece of square key stock or similar You can put it into one of the notches so the pliers have a purchase and allow you to torque without squeezing s hard.
Or do as most old timers do, and use a dull chisel and drive it off with a hammer.
BTW- make sure you're turning the ring in the right direction, and not simply tightening it.
