Old school skyway sprocket - how do I get it off?

(1/7) > >>

Plinth Adenoid:
Hi all

My build is coming along nicely, I'm currently cleaning the rear tuff before dipping in bleach. As I want to ensure the hubs are protected from bleach this time (the front hub is a dull grey colour now) I am in the throes of taking the sprocket off (it was missing a number of bearings, slipping and wobbly as hell anyway).

I took the front of it off, left handed thread, millions of tiny bearings everywhere... out came two shims and a spring with two teeth on it but now I'm left with this and can't get it off.







I've tried big mole grips, drifting with a protected screwdriver etc but it ain't shifting...

Help!

Thanks again for a fab site everyone.

Have you tried it with the axle out  ???
That may be holding it in  :-\

or just use loads of grease  :LolLolLolLol:

i'm not sure  if you got a suntour cassette style hub or not, (but if yes, this might help against the wobble:

Moose:
How did you remove it? Did you use a special tool?

Did it look like this before you removed anything?

Plinth Adenoid:
Yeh it did, except it's a 16T SIA sprocket. I undid the front race (clearly not the way to go, I've recovered 78 tiny ball bearings so far...)

So I took the toothed wheel off and what's left is the bottom bearing race. I think it's screwed on by looking at the fit. I might just buy a replacement and leave the old race in place, it's in pretty good nick.
