stuck lockring on Shimano cassette
I need to remove my cassette so I can replace a spoke (yeh, always the back wheel...) but I can't budge the lockring! I have the right removal tool and a sturdy vice to hold it in, so I SHOULD be able to get enough torque (if that's the proper term?). Anyway, I've taken the axle and bearings out just to ensure I'm getting the splines of the tool and the freewheel well engaged (they were due a regreasing anyway). I've put WD40 on and let it soak for 30 minutes -- won't budge. Then I soaked it with Gunk Liquid Wrench, tapped the lockring lightly with a wrench, and waited -- still won't budge. My plan now is to let it soak overnight, not having any other options unless you can give me some suggestions. Of course, at this time of the year, the LBSs laugh if you want them to do something in the next 4 weeks. Heat might help, but I don't have any sort of torch AND I'd be reluctant you use it anyway. Ideas, please? rcd
