- 2 Magntos stripped and rebuilt.
I'm no expert with Magnetos but you may be interested to see one stripped and rebuilt.
There are quite a few guys on UA-cam who have the knowledge and skills required to carry out a full restoration, check them out, I did.
Thanks Brian I am just on with mine. I have the exact one for my 1956 Ariel NH 350. Top job.
Thanks for the comment, good luck with yours. Cheers B
Almost therapeutic watching a Master at work! 😃 Another fine job from our friend from across the pond!
Thanks for the comment,always appreciated, cheers B
It's always good to see the master at work, thanks Brian. PS. I did as you advised re fitting main bearing (casing in oven, bearing in freezer), and it practically fell into place, no bother at all :-)
Thanks for the comment Dave, glad you enjoyed the video, hope your bikes coming along Ok.
Cheers B
@@500dbd34 Bit of two steps forward one back re bike. I had to re-strip engine in order to solve a weird whirring noise, which was caused by a worn main bearing outer washer. Which, in turn was caused by a worn breather collar locating pin. Nearly there now :-)
Very nice job Brian. I've never had a motorcycle magneto apart so it was interesting to watch.
Best wishes, Dean in Oxfordshire.
Me to, glad you enjoyed it. Cheers B
I've serviced a few of my own over the years, and you cant beat a new condenser for getting a new lease of life out of a tired mag.
I agree. Cheers B
Nice job fella. That's given me the confidence to tackle a rebuild on mine so I can get riding again :)
Glad you liked it, good luck with yours. Cheers B
Good work
That unknown now sure looks beefy and has a great spark!!! I am a new subscriber and I want to see what is inside a Lucas Magneto....Thanks.
Thanks for the comment, glad you enjoyrd the video
Thanks Brian, very enjoyable
Thank you, cheers B
Superbly educational 👍👌
Thanks for the comment, cheers Brian
Do you prefer the loose wire advance , from pictures , the cam plate looks the same . I am just getting mine rewound pretty sure the condenser was bad , and might convert to the loose wire end housing . Cheers
@@Cobra427Veight hi, I’m not sure if the camplates are the same, I have both slack and tight advance mags and prefer the slack advance type.
Less chance of slipping back when on the road. Cheers Brian
@500dbd34 I bought an end housing with a face cam and im going to convert to Slack Wire. I would agree with you on tight wire .face cam did look the same in the picture, both have a notch to engage the end bit on the opposite side. Cheers
It’s great watching your utube videos, thank you so much!
So your new spacers eliminated the old large shim spacers? Do you mind adding the name and contacts for the armature rebuilds? Are the new condensers a stock old style type buried in back internally? I’ve seen new style that bolt on the front but never bought one.
I was surprised finding out that the bearings must be mounted inside paper gaskets to eliminate the electric flow or is it grounding out? I’ve purchased some and they offer different thickness gasket material . I’ve never known which thickness of that to put where? Perhaps that’s standard in all magnetos but what a design!
Thanks again for your all your efforts, very inspiring help for working on great old bikes.
Hunter, thanks for he comment, when I stripped the Mags I noticed thin shims under the inner bearing races at both ends as well as a full size thin shim under the end plate at the points end. I played about with different shims (trial and error) until I was able to eliminate all end float. Still not sure if this was the correct way to go but it worked.
The company who rebuilt the Magneto were in Preston, Ribblesdale Auto Electrics Ltd., they rewound the armature and fiited a new condensor, (old style) with a 2 year guarantee.
Cheers B
Hi Brian,
Didn't you have to charge the Magnet since the coil was removed, also the whole cleaning process etc which usually makes it weaker every time the coil gets removed?
Thanks for the comment, One of the magnetos had a better magnet than the other but I never changed either of them. I wasn't aware that cleaning made the magnets weaker. either way both Magnetos are working well with bright blue sparks. Cheers B
😢super work from india
I just got my exchange armature from dragonfly, but the small end points shaft with the notch is missing , I didn't know it came off , I can see a small thread and maybe a keyway , are these available? Can you check yours and confirm this part is removable. Cheers .
Sorry, Ive not got the mags now, look up Dave Lindsley he may be able to help. Good luck.
Hi, great video. Could you please tell me where you got your magneto parts from ? Regards Chris
Hi, most parts are available on line or Ebay, the bearings are available for any bearing supplier, the bearing insulators- Ebay. Check out Dave Lindsley, he keeps most parts for the MO1. Good luck
Cheers B
Thanks Brian
Sir, I have question. 1. how to take out slip ring
2. How to check amature using multimeter?

1st class demo
Cheers, glad you enjoyed it.
Good work sir.india
Where did you purchase your spare bits?
Hi, the bearings are made for magnetos and area available from most suppliers , the insulators are available on EBay as are other parts. Check out Dave Lyndsley who can supply most of the parts you will require. Good luck, cheers B
@@motown1703 Dave Lindsey is probably you best bet, he can supply all the parts you may need.
Where did u get the condersor
The condensoe was fitted when it was rewound.Ribbledale Auto Electric did that for me.
Fgood vid except you shouldtorque the nut on the slipping clutch so a kickback doent damage the dynamo, think it should slip at 7ft.lbs if memory serves me.
Thanks for the comment, never stop learning.
Cheers Brian
