Shimano Alfine diagnostics
Hi I was wondering if anyone has experience with Shimano Afine hubs? I found this wheel in hard rubbish and was considering trying to install it on a bike. Here I’ve got it mounted on my Kona sutra with the chain running through the derailleur. The wheel seems to turnover okay when I pedal the cranks and isn’t noisey at all, but I don’t seem to be able to change the gears at all by pulling the lever that the cable would usually activate. I understand these have years required dedicated shifters and don’t work with the usual Shimano indexing system. Is there some way of determining whether this hub is stuffed or whether it may be resurrected bull, without spending too much money? I was hoping not to have to invest in a shifter if it’s not worth while because it’s damaged etc. any advice would be much appreciated!

Nexus/Alfine hubs require precise adjusting of the selector lever, the cable pull is critical too. I don't know how you can check that hub without a dedicated shifter. A Revoshift is around $20 IIRC.

thanks for your reply. I can’t find any revo shift that is Alfine specific. The only Alphine specific ones are rapidfire they’re a lot more expensive. I wonder if I can put my do your bar and shifter take it out of the indexing position to continuous, just to see if I can get the gears to change. I know very little about these hubs but I understand the regular shimano Sis shifters are incompatible and presumably run at a different tension.

I think you have probably done enough to show there is something wrong. One interesting question: are the sprocket and hub rotating at the same speed? If so, it might be an indication that the mechanism has seized. In any case, your next step should probably be to clean and re-lubricate. I think there are descriptions on the web of how to do that without buying Shimano's special-purpose oil. That would probably be the best next step even if it seemed to be working ...
