[Closed] Grrr. Seized and now rounded locking.

No one got any tips?

Looks like I'm stuck with 18t cog then....

Saw a notch in it to gain purchase with an expendable screwdrive. Then, using screw drive in a chisel like manner hit it with hammer to drive the lockring round?

Worked to get Cheiftain bb cups out of a frame after a similar incident.

Use a cheaper tool next time, so the tool lets go before the lockring does? 😆

You'll not knock it off with a hammer and chisel if the proper tool wouldn't shift it.

I'd be looking to find a garage or engineering firm who could weld a cheap 1/2" drive socket to the lockring and remove it that way.

Biggest Stilson wrench you can find.
Obvious but make sure you're turning it the right way.

have you already used plusgas or something ?
(adds: it will strip out all your grease though)

I had one really stuck once, it was one a wheel I hadn't used for a few years and it really really wouldn't budge. With careful use of a rotating cutting disc on a dremmel I managed to remove the lockring without damaging the freehub. I cut through it as far as I dared and then it was fairly easy to bend/snap the lockring inwards. It was a cheap Shimano hub so I wasn't too bothered about damaging it, but it survived intact.

Any tips, bloody thing just wouldn't move, bit more grunt and the tool has rounded the teeth off the lockring.
Suggestions?
CK SS hub so hope it's not buggered.

Ah just looked on the CK website - it's cassette type lockring. If completely rounded then I would get the Dremel out.

File the lockring down flat until it reaches the freehub body,The Ring should come off and then just un-wind the threaded part that is left in the body,With no tension on the threads it should unscrew easily.
