m910 jockey/tesion pulleys

[stingray230sx]

I just bought a m910 derailleur off ebay, came in todays mail so I was cleaning it up and it has a 11 tooth "G" pulley[sealed bearing]upper, and a 10 tooth "tension" pulley[sealed bearing] lower.
the lower pulley is wore to the point that the teeth are sharp and pointed.
it seems as if google search doesn't find anything except modern pulleys.

anybody know where to source a replacement 10 tooth sealed bearing pulley?

or am I stuck buying an aftermarket alloy type sealed bearing pulley, I did find a 10 tooth variant in that format.

thanks

Probably cost around £30 odd for some NOS ones.

Plenty of replacements from Taxc and BBB and ebay is awash with them.
All should both be 10 tooth though.

Re:

thanks FC, I have found some sealed bearing alloy in 10 tooth, so I will get those until I run across an NOS set for later.

the aftermarket do not seem to address the "float" that the oem top pulley has so I will just deal with it until I locate an original.


thanks again

Re:

The original is just a standard ceramic centeron. On most the higher level mech at the time .. Well XT anyway.
It has the ceramic tube in it rather than a steel tube.

Re:

yea, I found an oem xtr set but it was 75$ US by the time it was shipped, and yes it showed a ceramic bearing/axle so obviously the 11 tooth with a sealed bearing is a later pulley[it seems in good shape though], but I did find a alloy set with bushings etc to make the top pulley float[Toronto cycles has a lot of nice stuff].

so I will try these out and maybe one day I will run across an oem set.
