nothing wrong with using a cassette cracker on these: it just saves having
to use a vice. If squirting WD40 into the works doesn't get freehub working
again, then it sounds like the ratchet has had it. I've never taken these
apart, but according to Sheldon Brown http://www.sheldonbrown.com/k7.html,
they are servicable. I think you might have to buy a new hub: a perfect
opportunity to learn how to build a wheel. I have the tools you would need
to do this, and Sheldon Brown tells you how. Conversely, you can get some
very good deals on built wheels, and it could be an opportunity to optimise
your gear ratios.
thanks for all your ( > 10 ! ;) replies, they were all very helpful! I've now
stripped and cleaned everything, down to the point where I need to remove the
fixing bolt as per:
(sheldon brown rulez!)
and lack a 10mm Allen key. At least I think i do . . . the fixing bolt has
splines on it so it *might* need a special tool, but it will probably mesh
with a 10mm allen key. I also received a possible offer for a spare freewheel
but suggestions of price, place and availability will still be appreciated.
