Default JD D throttle rod linkages

I'm working on a 29' John Deere D and have a question that I'm hoping someone around here might be able to help me with. My tractor came as a wreck with many missing pieces, and has been in boxes for 5 years so some of the assembley has been a bit of a puzzle. The pictures show where I'm at with the throttle/spark controls hookup and all the parts I have are on there. I know I need another rod through there but I don't know what kind of linkages go from there to the magneto or the throttle bell-crank. I know I must be missing some parts but which ones? The parts book is a bit shady on the details...

Any ideas or pictures would be greatly appreciated. Heck, I'll even take opinons!

Grant, the end of the throttle arm that's pointing up needs to point down to connect to the rod coming from the throttle lever. The other end is OK, it pushes on the gov. spring, which is on the rod that goes to the carb. throttle lever. My D is a '31 which is a little different, it doesn't have the manual spark advance lever. Can't tell from your pic, does your mag have the manual advance? I know what you mean about the parts book, it's a little hard to figure out what goes where...my parts book is out in the garage right now, I'll get it & take a look later, there were a lot of changes in '31, so the '29 will be different.

Thanks Ron. I think mine must be different from yours in that the bent part of the crank rod has to point upwards because of the way the casting is. I guess I'll just have to find someone out there with a tractor I can look at.

Yes, now that I look closer I can see it can't point down. That mag bracket is one of the changes in '31. My buddy had a '30 for a while, but sold it, so I don't have one I can get a pic of...sorry...

Here is a photo of my 1924 D showing the mag timing adjustment and linkage. Should be similar to yours. Hope this helps.

Thanks hottube, that one looks a lot like mine. I can see there is some kind of arc-segment / half-moon looking bracket that bolts to the breaker box of the mag, and must connect underneath to the control rod. Now I know what it's supposed to look like. The throttle rod looks like it's bent upwards to meet the governer crank-arm. I can do that, but I'd have to bend it after I put it through the tube, which seems odd to me, as in not like something JD would do in the factory.

Good stuff! Thanks a bunch for the picture.

Grant,

I have a '29 D. If you need any more detailed pictures or information, I would be glad to help.

Hi Dave. Thanks for the offer. I sure could use a good picture of the front end of the throttle and spark rods where they come out under the magneto. I need to see how and what joins onto the rod ends and how they hook up. Thanks!

Grant,

Here are a couple of views. The first is of the throttle linkage and the second is the magneto linkage. The two rods run together in the tube. The magneto rod is straight and just has a rod end on it. As you can see, the throttle linkage is bent up with a rod end on it. By the way, if you need any more detail, I will be able to take more pictures on Saturday.

Dave

Thanks Ron, that's perfect. Now I know for sure what it's supposed to look like. It was a while ago now, but I think I might have straightened the throttle rod to get it out of the tube for cleanup. The tractor was in pretty poor shape when I got it so I probably thought the bend in the rod was not supposed to be there and I "fixed" it. :-)

When I restored my Wallis I did an awesome job of straightening out the bent steering rod, only to find out later that it's supposed to be bent to clear the right front wheel on sharp turns. Ha!
