I've got an older 8 speed shimano 600 derailer and need to replace
the
pulley wheels. I'm having a hard time finding a pair. Can anyone
recommend a source?

Thank you,
Bob

I believe the TACX stainless ball bearing ones should fit (they come
with a bunch of different bushings for different applications) and I
picked up a pair at my LBS for about $20 which seems to be the going
price online as well. I used them in a 105 9-speed rear der. so I
can't exactly answer your question, but I think they should work for
you.

Tacx makes 10-tooth and 11-tooth replacement jockey wheels, you
need the 10 for Shimano 600. A pair of the 4050 used to be under
$10 but getting a little harder to find. Ball bearing version will be
more expensive, currently
probikekit.com has the 4060 set with stainless bearings for $13.43
USD which will work just fine for you.

I may have erred and you need the Tacx T4000 for the older
Shimano 8sp, check the tacx site out.

I'm going to say it anyway. Have a decent bike shop around? They
should have them, I do, many others on the NG do also(Andy Muzi, Mike
J, others).

indeed - get shimano oem wheels - they have the required side-float in
the top one. aftermarket wheels have ball bearings, not sliding
journals, so don't accommodate this function.

Speaking of sliding journals in pulley wheels, which part is supposed to
slide?

Is it all supposed to be spin around the bolt itself, or is the nylon
wheel meant to slide around the sleeve that the bolt goes through? Or
either/both/nobody cares?

a sloppy guide pulley is only required for a sloppy derailler and
cable installation.

there's a sleeve fixed inside the wheel which can slide and rotate about
the sleeve that goes outside the bolt. high end modern shimano uses
ceramic journals which are virtually wear and grit proof.

Thanks. I think I saw the outer sleeve in the top pulley, but not in the
bottom one. Also the inner sleeve seemed rather a tight fit in the top
pulley, which is why I wondered if the inner sleeve was meant to spin
around the bolt.

So is the float produced by having a bit of a gap between the bolt and
the inner sleeve?
