Wagger, thanks for that - as it is raining today so all planned outside activities cancelled I might have a look at some videos as you mention.

Maybe I should just right it off and regard it as a possible source of spares . . . BUT I don't like not being able to get something sorted. I'm going to think it through for a day or two before deciding whether to order a bush or not, the drop dead date will be when the item I do want becomes available with the same supplier and I place my order for it and some other stuff. I thought of changing the title to dynamo but can't seem to get the option . . .

Wagger : Thanks for the explanation, but I think I'll give it a miss and have another drink instead.

Is there any way I can test them?

Don't blame me I was just quoting johny. I don't know the difference between a tap or a valve. Robinet ou vanne

I was worried I was over oiling it! I'm a dinosaur, so its a dynamo if at all possible. By the time the fitted one fails there might not by any choice though.

Thanks for the kind offer. I do have a working one fitted so this one is a 'training' exercise so I have a spare to hand. As for getting to anywhere in the UK - to be blunt No chance! Absolutely no reason to come over, Mrs. does from time to time for pleasure but my last 3 visits have all been for funerals of parents. I don't even have a passport anymore

Ok, so I took a big hammer to it, well alright a medium sized one, any tiny screwdriver as did as you say - the result was as you said. I did look in my stock of bolts, the biggest I had was 5/8" which didn't grip enough but would have done had the bush not been so worn - then again if it wasn't worn I wouldn't have wanted to remove it . . . Before getting brutal I did test it out on the bench as a motor, it turned but really quite slowly. From memory when I did it before, back in 2015, I'm sure it turned very quickly. The battery I used was well charged. It is now semi disassembled and I have added a new bush to my 'reminder' list with the supplier. I have a number of items on hold waiting for one to come into stock, delivery keeps getting put back - latest is 30th June. So progress will be slow. Thanks to all for your comments, much appreciated and even better helpful

What did I press, Anyway, now 521 because of the error. Just go to the forum on the website it lists topics and give the number of views.

519, sorry 520 with this one. Just go to the Forums he

Now you're resorting to the violet methods, I like it! As the bush is well worn with the looks of it there can't be much meat left in the metal so worth a try, after all nothing to lose. Was beginning to think along the same lines, or even finding suitable bolt and carefully screwing it in until it bites then pulling the bush out.

And it has to be fitted during a month with an 'R' in it one a night with a full moon . . .😁 I'm beginning to wonder if it is worth the hassle, the cost is still reasonable even if I have to buy a metric equivalent of a 5/8" tap, maybe my friendly garage man has one? He only took over the business in May and he will soon learn to but the 'Fermeture Exceptionnelle' sign up when he sees me coming...

That seems to a shared view. The 'stuff' between the segments seemed to be very solid so I thought it might be a resin put in to stop particles getting in between the segments. The gaps between the segments where the brushes touch are clean. That would be no cheaper I guess than a locally bought genuine article. Bronze then, not a bit of left over copper plumping pipe 😁 Lunch time (13h00)

Did my research and it did confirm what I thought, and what you say, the bush isn't any part of the circuit. I didn't think yesterday to test it as a motor, I did do that a few years ago with the old unit when I replaced the brushes. I did bench test the dynamo yesterday, a drill provides the mechanical input. I did wonder if there was enough movement in the rotor to allow it to touch the cores, the photo I took before it was cleaned up seems to confirm this I will give the dynamo the motor test to see what happens. No panic to sort it as the original dynamo now fitted seems good (oops, that's blown it) but I wouldn't mind having a standby if the faulty one can be repaired at a reasonable price.

I need to look at a schematic for the dynamo (or a generic one) as, to be honest, I'm not clear that the worn bush is the cause of the dynamo not working, is the bush part of the circuit? No point in replacing the bush if it still won't work Research later today . . .

Yes I know but as you know postage can be an issue plus there could no doubt be 'customs clearance' charges. fpr instance RB where the bit is 3€49 the all in price delivered comes to 29€34.

And getting the remains of the old one out?🤔

Can you put up the details, please? I don't mind paying 14€40 for a bush rather than the 125 that one French supplier is asking for a new dynamo (GXE3101), but if it can't be fitted no point. although having said that when I was at my friendly garage up the road yesterday I did notice a very new looking press in the corner . . .

I should have done a parts search before asking you, found it on the Canley site. 509304, now to see if I can source one without having to import from the UK. Found it in stock under the ref: 7H5390 with a supplier that I have several items on standby waiting for a couple to come into stock before ordering. They want 14€40 for it. I shall keep looking . . This post was to have been put up just before 18h30, French time. I pressed the submit button and ,just by coincidence I think, the internet and mobile phone network crashed. It has just come back up and due to the wonderful forum here my comment was still there!

Did cross my mind that it might be replaceable, I'm talking about the end with the felt pad, wondered about looking at my bits of left over copper plumbing pipe for something to whack in 😱 Any details of the bush, description/part number, that I can search for this side of the water?

I've thought about fitting one but don't want to scare the life out of anybody nearby when it is in use, just loud enough to be heard above the other background noises, birds twittering, rivers running, bits dropping of the Triumph . . .

Sorry to interrupt the musical reminiscences . . I got my household tasks completed early so had the right to a bit of personal time. Took the dynamo apart and the inside looked as if someone had taken a spray can of copper slip and liberally coated every surface. I cleaned everything off, what would I do without a can of brake cleaner on the shelf. The only 'damage' visible was the interior at the end where the felt pad is. There seemed to be quite a bit of a gap between the rotor(?) and the body of the end piece. Put back together and tested it by spinning it with a drill, maximum voltage was 7.15v, mostly only 3 to 4. Unit is now back on a shelf labelled 'doesn't work spares only'. The pale brownish stuff is what looks like copper slip, you might be able to see that the centre is worn. Looking down the inside of the body The rotor before cleaning

In turn refit each of the old stuff one at a time until . . .

Once again you evoke a classic piece of music. I assume you know it's origins?
