Schlumpf hubs: general discussion

Picture of the complete KH/Schlumpf gearing shaft

Hi all,

In an attempt to participate into building some kind of “knowledge base” (on top of posts such as this one) for whoever might be willing to maintain their KH/Schlumpf hub by themselves (at the cost of losing the warranty of course), here is a picture of the gearing shaft, fully loaded with all the related parts:

Note that I’m not 100% sure yet about the above ‘sequence’, because I’m still working on my hub at the moment, and will only be confident into my “findings” the day I will have built my hub again and get it confirmed that it works as expected!
For instance, the “spacer” has got a thicker end, turned rightwards on my picture. This actually results from a guess on my side more than anything else, as I was not cautious/careful enough to record the leftwards/rightwards orientation of the spacer at the time I removed the shaft…

Also note that, for the same reason as exposed above, I cannot advise anybody to try and remove the shaft from their hub, because I still have to demonstrate that this doesn’t damage any of the hub’s parts. That’s why I am not documenting in this post how I actually managed to extract the shaft from the hub (though the picture itself might be quite self-explanatory about it?).

At the moment I am trying to remove the “real” internal parts of the hub, but even though I removed the 9 screws and screwed in the 3 screws in the dedicated threads to help in the process, I do not manage to extract the “whole thing” from the hub shell… I suspect it might be due to the fact I have not yet removed the C-Clips on either side, something I will be able to verify either today or tomorrow…

Cheers, MadC/Pascal.
