Have been trying to get the lockring removed from my cassette so I can replace it with a spacer kit and one sprocket (singlespeed conversion). I managed to get it loose, although the wrong way - so the whole cassette started unscrewing off the hub. I can't turn it the other way at all. Can someone confirm:
I have a chain whip, lockring tool and 24mm spanner/wrench.
If it screws on then it is a freewheel not a cassette. They are not the same. There is a link in my comment.
Your spacer kit with one sprocket was probably for cassette / freehub. It is not going to work.
I suspect you can find a freewheel single speed conversion.
You need a single speed freewheel - not a sprocket and a lockring.
This is a freewheel, not a cassette, and thus it has no lockring. It does have the ability for a skilled and careful mechanic to disassemble and replace bearings, to rebuild it. However, it is cheaper to simply replace it.
take a sparkplug 3/4 make sure that the back willfit inside the freewheel of the cog and no axle is there it might need a little hammer tap to get the six sided part down in there make sure u dont mind scratching outside of socket then u need a pipe wrench or good table vise and grip socket turning wheel counter clockwise for it to thread off the hub..
