I wouldn’t recommend the use of three in one oil in an SA hub. Three in one might penetrate, lubricate and protect but the protection includes laying down of a layer of gum. I suspect that lots of folk have used three in one for years, topping their hub up on a regular basis, but when the top-ups stop and it dries out guess what happens …
What lubrication would you recommend. SA do not make their own lubricant anymore.
Fixed that for you, I hope that that’s OK. :)

There are some good threads on what oil folk use, what’s near to the original SA oil and what’s even better. I use Singer Sewing Machine oil (which is a light machine oil) in my SA AW, there might be a gain to be found using something different but (to me at least) that oil seems to be ‘in the right ball park’ - and similar to the originally used SA oil. Over the counter (ie. in a shop) Singer oil is around £3-50 per bottle, prices will vary by location, and it’s widely available by mail-order too. Though I’ve not used it SAE 20 motor mower oil is, I believe, a sound choice too.

Edit. Try reading this thread : viewtopic.php?t=150384
Have you seen this, is it any good?

Sa was working fine yesterday, today gave cleaned and replaced all cables.

I also gave SA flush though with 3 in-1 oil.
I remove the control rod in top gear.
I put the control rod in and pulled it, but it had resistance!

I tried some more 3 IN 1 but it only helped slightly.

Does it need a disassembling?

What lu icaruon would you recommend SA do not make their own lubicate anymore.

I am also having a problem, I thought it was chrome steel that was recommended, but now it seems it is carbon steel bearing I need

Re: Wiring hub dynamo

Many thanks, that is what I needed. I have been doing it wrong.

Thanks again

Is the bit you had trouble with poking the wires through the two holes without them catching, like the second step in these photos?

It can be fiddly but twisting the strands helps, and like Brucey said ensuring that the holes are clear and unobstructed. Solid core wire would be easier to thread but it's not suitable. It is stiff and will break over time because it's not flexible enough.

Did you manage to get it done ok in the end anyway despite it being a faff?

For what is worth, I wouldn't worry too much about cable covers etc, the plug itself isn't designed to be waterproof and water gets in between the plug and the tab it fits onto anyway. The best thing to do is put contact spray/other suitable substance on it so that it doesn't corrode. Current is not high enough for the presence of water to create electrical problems. I think that I'm right in this but would be interested to hear other opinions. In any case I've only had problems with corrosion but not the presence of water itself.

Wiring hub dynamo

Wiring hub dynamo
I had to wire up the hub dynamo, I used five-strand cables that came with the front light.

I had to insert the cables into the Dynamo Bike Hub Connector Kit SP
https://www.ebay.co.uk/itm/256364258882 ... 0yEALw_wcB

Even though I twisted the 5-strand cable, the cable kept bending or unravelling when installing.

I found it difficult and time-consuming,

Question

Any view on using a double-core single-strand cable like this, say size 1 or 1.5 mm?

So, using two separate cables I need to use a cable cover for protection.

Apologies if I upset you. It's just that £30 odd for a book with no positive reviews is a bit much IMHO.
