Using same jockey wheels on Huret Allvit RD

Ahh, the rabbit hole of vintage bikery continues. So the jockeys on the Crescent bike I'm fixing up were all chipped up - these were are ones without teeth that came with the Huret Allvit RD.

So ebay to the rescue and I find a pair in my neighbouring province of Alberta. One of them fits like a charm, but as I was disassembling the derailleur I noticed that one of them has small threaded piece - that threads on to the derailleur cage. They are actually two different part numbers! #2140 and #2133. So should I just say screw-it and use both of the unthreaded jockeys? It seems to work, but using the unthreaded one will give it a bit of "play".

I can't attach images yet, but some of you will have seen this diagram in other threads.

I'm guessing it's engineering decisions like that that put some of these old companies out to pasture? Seriously whey two different wheels???

Here is ye diagram:




If memory serves me correctly, you can take the pulleys apart, and only the center part is different between the two. This means you could use the center part of your old threaded one and put that in the plastic outer part of your new one. Be careful - there are quite a few ball bearings in there and I believe also shims. If there are shims (I can't remember), you may have to adjust the shim pack to get zero free play without binding, but you'll have a lot of shims to work with because you have three pulleys (your two old ones and one new one). You should be able to get all the ball bearings to stay put with a little grease while you reassemble.

scarlson you are awesome! I never thought the center parts of the pulleys were removable bearing cones - and yup, a couple of 13mm wrenches and I was able to pull the threaded center cone from the old jockey and use with the new one. Plus now I have a spare bearing set for down the road.
