Full width rear hubs

Posted by Dan Field at September 14. 2018

I bought a couple of full width hubs for not very much at Netley, I’m using the best one  for a special I’m building, the hubs have brake plates but not bearings, spacers or stub axle. That’s all available from Andover etc, but the bits  are not cheap!  I’m thinking of dumping the stub axle and running with a single full length axle ( pre featherbed swinging arm frame). Has anyone done it before? It looks easy enough to make up some spacers.

Hi Dan, I think you should be able to do that although obviously you will lose the QD facility.

A related topic: I recently decided to investigate (not before time!) an apparent ovality in my rear brake drum ('56 19S, full width hub). I fitted a new drum/sprocket but with little improvement. I went back to the original drum and marked the hub with the 3 possible orientations wrt the drum. Fitted the drum in position 1 and measured the run-out, then repeated for for positions 2 & 3. In the best position I obtained an acceptable run-out of around 0.005". In the worst position it was nearer 0.018". Hub and drum are now marked so it will always go back in that orientation. I assume that there are small manufacturing errors in both components which almost cancel out in one position but add in the other 2 positions. The best result with the new drum/sprocket was again around 0.005", the worst was better than the old one at about 0.012". Maybe this is well known but it took me the best part of 40 years to find it! If you think your drum is out of round try repositioning it on the hub. You may not need a new drum after all.
