Please help. Last October, I had a dynamo lucas refurbished. My mechanic died suddenly. I got it back yesterday. The dynamo is completely disassembled. I have a problem. I don't know where to mount this spring ring. Can you please advise me?
What is the catalog number of this part? This part is broken (photo from ebay). I have to buy a new one. However, I can't find it for sale.

Big thanks.

Marcel,
That part looks to be from a Magneto not a dynamo. It fits up agains the armature on the drive end of the shaft, it should have a thin insulator at the back of it which goes up against the armature. Some adjusting shims and an inner bearing ring keeps it in place.

Hi Tim,

Thanks for advice.If I understood correctly, is this item 451 378?

Marcel 451378 is just a paper insulator the stop any earthing current running through the bearings. Ron

The part is the "oil thrower" for the drive side magneto bearing. It is there to keep bearing grease off the slip ring. It goes between the slip ring and bearing shims. It should have a varnished cloth insulating washer between it and the slip ring. It is part number 463944 in the drawing below.

Yes. Yes.:) That's exactly it. I also understand the functionality. Perfect. Many thanks for the help.

I can look for where to buy.

Many thanks!!!

The steel plate you are looking for is called an oil slinger & it goes on after the Bakelite slip ring, often glued to the slip ring with a thin linen washer. No one makes them, but I have some extras
