D2 Wico magneto part #

A 1940 D2 would not have come with a Wico mag, there may be several Wico # that would be spec for replacement.

I don't think I have any for a look-see. The American Bosch would be an MJK 4/2 360.
I think I have a Prestolite, and a Fairbanks-Morse if that info would be of use.
Will update if I find anything.

The D2 WICO magneto parts number is 4s6471 counterclock wise

The D2 WICO magneto parts number is 4s6471 counterclock wise

That is the Caterpillar #. The wico number for a suitable sub would be different.

So I am now convinced more than ever of my mag issue. I went to try and give it a go this afternoon after my hot start issue and it wont pop at all. It will spark the plug but its quite white. I felt it while I pulled it over and the spark is so weak now I don't think I could bump a mouse out of cardiac arrest with it. I think i'm going to have the coil rewound instead of locating a Wico replacement as I would like to keep everything original as possible. Thank you for everyone's input. This forum is always such a great collection of experience from all over the world.

Try Mainely Magnetos in Maine - has a bunch of Eisemann spares including coils I believe

Hi Pioneer 1930,
The wico magneto used on D4 and D2 is a XH-1906.

Thank you Rax200.... I have located a couple of coils and some rewinding services and to be honest the cost of owning this Eisemann mag is starting to shock me.....(no pun intended)…… I think some enterprising Eisemann enthusiast needs to start making some replacement parts as the current cost of a coil alone is alarming to me. Once I got my copy of Neil Yerigans book years ago I have serviced and rebuilt all of my mags and have bought or made tools to service them as well. I am in no way begrudging anyone in the mag business or any other related buisness making money let me be plain and clear about that. Its just as the years go by and I see the costs of certain things go up in relation to other things it just kind of makes me sad to see something as wholesome, educational and just plain fun as collecting and running old iron of any type becoming expensive to the point that it may prohibit maybe younger folks from being able to keep this whole thing going.... such is life I guess...…...
