I need help with my 1975 Sturmey Archer AG rear Dynohub (rear 3 speed) please kind sirs!
I have been successful in adjusting more common AW hubs in the past (cones and cable adjustments) but have never had one apart. I have my wheel place loosely in a frame which is stopping the axle from turning - not set up in a ridable bike
With the AG I've got all the correct parts and I've adjusted the righthand cone correctly as per online manuals and Sheldon Brown advice.
It's the left side and the Dyno part that are proving tricky and I'm having trouble finding anything specific to my problems online!
The left hand cone (held by a four slotted washer) doesn't seem to loosen and tighten like a normal cone (my righthand one for example), it just seems to have a 'sweet spot' where it's bang on in terms of adjustment.
Once I have the cone locked in place the Dyno section binds and judders when I freewheel. So I back off the lock nut and the cone turns on it's own which helps stop the juddering but any attempts to lock the lock nut result in the dragging again.
Is my LH cone threaded? Or is supposed to be like that - ie unthreaded - as I can't seem to thread it off the axle? Why when I try to lock it in place does it jam up the rear wheel? Also, why is my Dyno part binding?
Final issue, the two small terminal nuts just spin and don't tighten or come off!
Sorry for the dumb questions and poor explanations! I've not attempted setting up the indicator rod or cable and shifter yet.
Please help if you can, I've been fiddling with this for about 5-6 hours now
