I worked in a bike shop back in the 70’s and tore these things down all the time. And coaster brakes. One day, I was trying to fix a bike with a coaster brake hub and the thing kept slipping somehow in a ways I had never seen before. So I tore it down to clean it up and I found the usual stack of brake discs, but something else I had never seen before. There was a ring of gear teeth inside the hub, and two huge pawls that were not properly mounted… or so I thought. I fiddle with it a bit and then it began to dawn on me, They were large to be heavy and they were spring to swing out when spun at a specific speed. I put the thing back together and sure enough, it was a two speed hub with an Automatic Shift. ( not one of those 2 speeds where you kick back to change gears. ). You would get the crank going at a good clip and then CLUNK, it would suddenly upshift to a significantly different gear and your cadence would be slow. Made by Torpedo. Perfect for a really great “single speed” fixed gear bike. Except it downshifts automatically when you slow down or stops and upshifts just when your cadence starts to get too fast.

Perhaps you don't have access to one, but a vise to hold the hub securely in place would be a big help. That said, you did a very nice job on a seriously neglected hub. Good to see this beauty back in working condition. Thank you...

Sir, Lot's of love n thanks for ur clean n clear video. Sir I have got 3 Geared Raleigh Chopper 1978 Mk ll model Bicycle in running condition with all original part's except Tyre n Tube.🙏🙏 ( INDIA GOA )👍👍

I think this is a great video, very helpful! The attention to detail is on point.

What a well-photographed video with attention to all the details! Thanks for sharing. However, respectfully, you made a very important error in using grease to lubricate this hub. Many mechanics use grease, not knowing it's the cause of the most common problem with these hubs, stuck pawls (ratcheting mechanism). You are supposed to use light oil, not grease. With grease, if the hub is neglected and not regularly cleaned and the grease refreshed, the grease gums up (becomes sticky) and the pawls get stuck, and possibly the indicator rod (which changes gears). Also it will cause more friction in the gears. You are supposed to put 2 teaspoons of light oil when rebuilding a hub, and a few drops every week or two through the oil hole. You CAN use grease for the bearings, however. The grease there helps to seal the light oil in the hub, as well as keep dirt and water out. These recommendations are from the Sturmey-Archer service manuals, as well as sheldonbrown.com.

I used your tutorial and it worked! Thank you so much for the clear explanation.

Buen trabajo y muy bien detallado. Lo mejor que he encontrado sobre este asunto

The best teacher

Great tutorial 👌 Thank you so much.

Nice video sr thank you for taking your time to make the video

Very nice detailed video… thanks

Thank you very informative, nice andcalm with short cuts, Terry gray.

Great video liked and subscribed thanks for this very informative

Thank You very much i from panamá 🇵🇦

5:14 These rings can be really stubborn! If the wheel is complete still, you can hold the wheel rim as a form of counter leverage while you hit the punch. It's also amazing the state these hubs can get and yet they still can be restored.

Well done an excellent video..

great job! Thank you

Lots of parts to remember.

tnx for additional knowledge...

Why did you put both spacers under the cog, when, originally, there was one on each side of the cog? Thanks

Great video to help me repair my Raleigh Chopper hub...........I noticed you put 23 ball bearings back and there were 25 originally !!!!!

That small black cap on the inner housing is that a cover for an oiling hole? Thanks!

Dzięki!

very good

thanks, very good

Thank you !

I usually dismantle from the break side. That way I know for sure the springs and what not wont just fall off. Torpedo Dreigang for example...

GREAT VIDEO, tHANKS. mY PAWLS ON THE BOTTOM OF THE PLANET CAGE LOOK DIFFERENT. YOURS SEEM TO BE LONGER ON ONE END THAT THE OTHER AND MINE LOOK LIKE THE HOLE IS EXACTLY IN THE MIDDLE OF THE PAWL.

Good hard work and very rusty Hub made to work I have enjoyed watching you hub overhaul I have one concern regarding grease where moving part you could put oil and also in middle of hub there is oil cup. what do you think ? I am entranceting your answer. I am from England.

Thanks for the video. I think I made a mistake reinstalling the clutch as my 3rd gear does not work.

I hope that's not your Mum's best dining table under that piece of cardboard! 🤣

Marvelous video. I have a question: Is it better grease than oil to lubricate all the mecanism?. I ask this because, most of time, grease tends to stuck all the little springs. Hope I had explain it well.

The hub gears shouldn’t be lubricated with grease, only the bearings. Sturmey Archer recommend a few drops of SAE 20 oil (lawnmower engine oil) for the internal gears, with a drop or two added every 2 weeks via the filler cap.

Hi, your video was very helpful, I follow your instructions but unfortunately the bike is not working, after a few seconds cycling is blocking and the chain is going out. Any idea why this happen?

Goode 👍 Veri nice🥰🚴😆

What size are the bearings ? I am going to take apart 3 of them . Thanks .

on 36.46 you make a mistake: before you put on the square washer you should open the hub by turning the right hand bearing cone 1/2 of a turn, this is according the official Sturmey Archer guide. After opening, put the square washer and lock the right side

19:53 my hub gears did not have this spring, is this a problem? Also, the hog washer at 36:53 did not have the same shape, but it was actually a normal washer. Was working on a Sturmey Archer from a Brompton, so maybe they are different.

How did you clean the hub shell? You did not show how and with what you cleaned it with. Please show me/us how you got it so shine. Thank you very much.

Good job. Thank you so much. I want to know there type of Hubs are available in the market. I am from India. I have sturmey Archer single speed freewheels in my shop made in India in the year 1975.

Haven't you got a wire brush and a bit of oil for that spindle thread???

How did you get the rust away? Only with WD40 and a tootbrush?

Which one is better this or TORNDO MAKE ?. Kindly advise me... Thanks.

That's one rusty bastard :)

I hope the ends of your cross isn't polished. That's a ball buster!

Thanks for the video - I have same hub and want to replace the bearings - could you tell me what size they are as I have no idea how to measure them? Thank you
