Drum brake and 3-speed-oil issues with Sturmey-Archer?
I have a Sturmey-Archer XRD-3 which I'm thinking of converting to oil lubrication, but I'm a little worried about oil leakage into the brake drum. Is there something in the design of the hub to prevent this? I've definitely seen an old SA advert for a drum brake 3-speed hub with an oil cap in it, so presumeably there is, but I thought I'd check anyway.
too many bikes from 1967 10s (5x2)Frejus to a Sumitomo Ti/Chorus aluminum 10s (10x2), plus one non-susp mtn bike I use as my commuter
The British built SA drum hubs were oil lubed, using grease only for the ball bearings and dust seal. the drum side was isolated from the gear side and oil wouldn't get there unless it was over-oiled like crazy.
I don't know if they are making drum hubs in Taiwan, but if so, It's a fair bet that the brake area is likewise isolated.
