Welcome back - today a Sturmey Archer GH6 front hub.
I’ve had these sat around for a while now waiting for a service. Both hubs felt very stiff and clunky so after a quick look at RJ’s video I decided to service them both. It’s a pretty simple procedure just make sure not to drop the tiny little lock washers or separate the magnets!
As soon as I get a replacement multimeter I’ll be able to check if they generate any power.
Next up - the four AW hubs that are in the background!
Thanks. I watched RJ's video on the topic when doing a couple previous Dynohubs. Today, I watched yours while re-building another couple hubs.
I recently stripped a NOS 1948 front Dynohub. I had the original SA instructions in the box and it stated that the non-dyno side was the fixed side and any adjustment should be made using the washer with four notches on the dyno side. In my hub this washer was effectively connected to the cone so adjustment was possible but it required a crescent wrench to hold it. I also had instructions from a later model hub which said that the dyno side was fixed (like yours). So at some point SA changed the design and swapped which side was the fixed cone. (Of course all the cones came off anyway!)
I'm really enjoying your videos, keep it up!
"Quite simple to service..." That's poignant and true of most bicycle repair...subtle simplicity even with high engineering. Would love to see how you end up using these!
If the magnets are still working I'll pop them in a build some time.
Thank for all your informative videos
Good job fella.
Nice rebuild. What polishing compound are you using? You should do a video just for cleaning and polishing.
I just used Autosol metal / chrome polish. Nothing special
Can you tell me what size cone spanner you used cheers Tav.
Hi, can you make a video how to lace this hub on the wheel?
Very good work, thanks !!! I have had to disassemble the coil because of its bad condition and I have not put a magnet ring; How can I remagnetize the magnet, please ?; I need advice please. Thank you!
I don't know how to remagnetise I'm afraid
@@MonkeyShred Thank you.......
Is the “grittiness” you mention just the poles of the magnet causing drag on the rotor?
Nice work, just out of interest where did you get the bearings from? 🚴🏼🚴🏼
Hey Ade - I got the bearings from eBay (*starcycles sells them) or SJS Cycles also sell them. I believe the code is HSA284
MonkeyShred that's awesome buddy cheers 🚴🏼🚴🏼
The magnet came apart on mine. Is there any way of fixing this?
I'm not sure - sorry.
5:27 you really were inspired by RJ
Hi , good video, am looking for the rear dynohub overhaul with SA 3 speed hub? Can you do one or have you done one before please?
I might have one lying around. I'll have to check.
Really should have shown it working and actually powering a lamp
Maybe next time.
@@MonkeyShred No probs, I guess my child-like disappointment got the better of me there ;-)
