- This is the first part of my next project, a 1959 Dunelt 3 speed Touring bike. It's been in storage for years, so it's time to service the rear hub and get it to shift again.
Goed gedaan,
Thank you.
'I just want you to notice' that Evan is great at what he does. The explanations are unhurried and he seems to cover most things.
I am familiarising myself with the correct names for all the parts so that if and when I need to take my hub apart I know exactly what I'm doing. I'm also getting a bit closer to understanding how the hub works. Very helpful, thanks for making the video!
Thank you for your kind words. If you have any specific questions please feel free to ask. It might help you to locate a copy of The Bicycler's Bible by Paul Dempsey. The first edition was printed in 1977. In the interest of not committing copyright infringement I am not posting a copy of the pages online. However, Pages 186 and 187 of that book have a fantastic exploded view of this exact hub with 51 parts numbered on the diagram and a corresponding table listing the part numbers and descriptions. I hope you can find a copy. I am certain you would find it useful.
Great video, but I’ve still got no clue how I’ve lost 3rd gear. It’s a newer disc version. It is however on my diy e-bike. I did lace it up to a 24” rim myself. A new hub is inexpensive enough, but would rather not replace, lace up another one. To be honest, I really don’t need third gear. Bike will do 30mph on a full charge in second gear. First and second gear work fine. If I had 3d, I could lower the ratio, larger cog, make it where bike would do 30 in 3rd and get UP the hill even easier.
PS
The speed limit on all main streets is just recently lowered to 30mph and residential streets to 20, down from 25.
Any ideas on fixing my hub would be greatly appreciated.
Thank you for the compliment. On your your bike, I would start by looking at the cable tension on the shifter.
Great video.
At 30:15 you forgot to tell the shifter pin should not completely be fixed in the hub. I have seen people trying to do so and damaging the thread inside.
You tell that adding too much oil is not a problem. In Holland we usually have a drum brake inside and then you should not add more than 10 drops of oil.
Thanks for watching. I appreciate the clarification.
I took apart some never been dun they called it grandpa old garage oil service these things will run forever .
Well maintained and these will last forever. They are built like a tank.
@@NewLifeforOldBikes sure are
sturmey archer specifically says do NOT use grease....19.35 unnecessary, will be oiled under normal operation. mineral oil is fine. spring cap is not needed nor is washer under it. I assemble it dry (syops picking up dirt the oil it before assembling. pour in a couple of tea spoons of oil. Otherwise excellent presentation. should check inside of bearing part to make sure pawls have something to bite into. the fact that the oil leaks out means you have to keep checking it.
Thanks for the helpful info. I appreciate the input.
Good job evan i dun sturmey archer hubs red band bendx kick back hub yellow hub bendix coaster brake hubs shamino on a lot of hubs now
Thank you. I've only done a couple of Sturmey-Archer hubs. Most times I can run some penetrating oil through them, grease the bearings and just add oil and they work fine. This one was stuck. This bike had been sitting for many years.
@@NewLifeforOldBikes most every one I ever did where the same
You can buy the springs online. Lots of places sell them.
I did ultimately find them and replaced all four, but amazingly one pen spring worked just fine.
Greetings from Bristol. Thanks a lot. I have watched many vids on the subject , but the pace of your explanations is just perfect. I have done a few overhaul of the SA 3 speed hub. From time to time , I get a grinding noise coming from the hub when freewheeling even after having lubed every single component & almost drowned the internals with gearing oil. Any clues what can be causing that noise please ? Thanks
I appreciate the feedback. Chances are a bad bearing is making the noise in your hub. One or more probably has a flat spot. Unfortunately, no amount of oil or grease will fix that.
Thanks , you might be right as I did reuse all ball bearings assuming they are all good . I will check that . Thanks a lot .
@@luckyram3461i expect one or more bearings in the bawl ring will have a flat spot. The outer bearings (the ones in a race) would grind all the time if they were bad.
I've watched a few of these videos now and no one mentions the K804 Indicator rod on the non drive side? Mine is missing on the bike I'm restoring so I was hoping for some correct installation info?
I'm not aware of an indicator on the non drive side of the bike. I've checked the Sturmey-Archer manual I have and it doesn't show it. Is yours an AW-3?
@@NewLifeforOldBikes No, my bad mate. I realise now it's because mine is a four speed. Nobody seems to cover them.
@@dapdapbamban I wish I could help you, but I don't have a bike with a four speed or the manual.
