10-20 Mogul magneto cover

fixerupper · May 2, 2014

I don't know which YT forum is right for this tractor but I thought the engines one might be close.

I'm in the ending stages of freshening up a 1916 10-20 Mogul and the last thing I need to tackle is the mag cover. It's gone and never was on this tractor since the owner bought it 40 years ago. It looks like a small mailbox sitting over the mag. Finding a used one is impossible so I'm stuck with making one, which I can do but I need something to go by to get it as close to original as I can. I have seen a couple of pics of this cover on the net but not close enough pics to tell me much. I do have an owners manual and it has a parts section in the back that shows the cover but it still don't have exact dimensions. I'm also wondering what the mag cover sits on or fastens to.

Do any of you guys or gals have or know of a 10-20 Mogul with a mag cover that you could post a close pic of and dimensions of? It's not super urgent but the tractor will be leaving my shop in a month or so and time slips away. Thanks. Jim

I've got lots of magneto books, but would need
to know the make and model number of the magneto
in order to help you. Mogul probably purchased
their magneto someplace, and parts could even be still available. Is there a nameplate, make, or
model number on the magneto?

Sorry for not explaining clear enough. I'm bad for that. This is a cover that sits over top of the mag to keep it out of the weather. The mag itself was overhauled and works like clockwork. There is only a handful of these 10-20's in the world and I have no idea where the closest complete one is so pictures is the only avenue I can take if I want to make this cover look,authentic. Jim

Have you found THIS one?

Would an 8-16 mag be similar... there is one not too farm away it would be easy to get some closeups of.

Bob, this pic is a 10-20 without the mag cover. What we see is the mag alone without a cover over it. I've never seen this pic before but it is still VERY useful to me because it shows a tray of some sort under the mag, something I suspected might be there but couldn't see in other pics. The 10-20 I'm working on doesn't have anything under the mag except for the bracket the mag bolts to. Also I see in your pic the mag sits on round spacers with spacers underneath the bracket it sit on too. The one I'm working on does have the spacers under it and they are brass. The four 3/8" bolts that hold the mag down are brass too. I didn't know if the spacers on the 10-20 I'm working on were put there in place of something else that should have been there or not, but this pic verifies they are supposed to be there.

From what I've gleaned from other pictures the 10-20 had little changes done to it through the three years it was made, sometimes, seemingly at the sudden whim of the manufacturer. Jim

This is what I'm working with. After looking at your pic a little closer it appears the whole base the mag sits on is different from the one on the tractor I'm working with. Hmmm. The more pics I look at the more variations I see on these tractors. My pic is slightly blurred. Jim

OK, two months later I have the mag cover made and installed. Bob, your picture was very helpful as it was the only pic I have that shows the base the cover sits on. A very helpful person on another website sent me complete factory blueprints for the cover and another person took pics of his cover and posted them. That's what I had to go by when I made this one.

I also had to make the spark timing adjustment lever going by only fuzzy distant pictures and a parts blowup in the owners manual. I never did see exactly how the rod that goes to the mag attaches to the lever so I used my imagination. I think a turn buckle is involve but I excluded it. I bored a hole inside the lever and put a spring loaded pawl in there that bumps down into a series of holes drilled in the 'rooster comb'. Anyway, it's done and I can move on.

Look'in GOOD!

I'd like to see that tractor and hear it run!

It is a throttled engine that IH set on wheels and ran a chain from the engine to the rear wheels. It's hopper cooled, just a tank of water sitting on top of the engine steaming away. It'll be at the Albert City Threshing Show Aug 8-9-10. The owner usually runs it in the parades. Jim
