lockring stuck - help

amircp

I am trying to replace a cassette - something I have done before. However it's on so tight that I can't get it off. Any tips?? I have a park tools chain whip and a 25 cm wrench along with the lockring tool. Could be down to my puny upper body - due to too much cycling?

strange it is so tight. It may help to fasten the lock ring tool with the wheel skewer to stop it slipping, and using a longer spanner or large adjustable wrench - my lock ring tool has a 1/2 inch square drive fitting in addition to spanner flats, so I can use a long T-bar or even longer torque wrench from my socket set.

Maybe you could try securing the lockring tool with the skewer as noted above, then secure tool in a vice. Then get chain whip on cassette and use the wheel itself as a lever ... holding chainwhip firm with wheel. This may give more stability to what can be an awkward position.
Incidentally... I have always undone lockrings by pushing down on the tools. I am sure I saw someone recommend pulling up on both the tool and the whip. Seems strange as I am sure it would not be very efective ... but I have not tried it.
Cheers,

For anyone who's done basic engineering training, never turn a tool towards you, unless of course you like getting smacked in the face! Pushing down enables you to use your weight too.

From personal experience this is by far the easiest way to remove a lockring. You get a hell of amount of leverage from using the wheel.

Looks like I may need new tools then as I don't have a vide or t-bar thingy. Also one of the links in the park tools chain whip has bent so I can't be that weak!
