Farmall H governor throttle shaft housing

DanH · Oct 18, 2015

Putting back together our farmall h. Installing the governor on the tractor. Hooked up the governor throttle shaft housing to the carb and the governor connecting rod cover. The throttle shaft housing is not level it is out by 1/8 of an inch. I had replaced the exhaust manifold with a new one. Is it possible that the new manifold is lower than the old one. What can I do to fix this problem ? Has anyone else had this problem if so what did you do to correct this

Thanks Dan

All of the replacement manifolds come from either India or China, so there is part of your problem. I would start by putting the old and new manifolds face to face and see if you can spot where the difference is. If there is enough meat at the mounting flange for the carb you can have it machined down or up depending on how you look at it and get it to work. If the manifold is too short either add gaskets or go to a well stocked auto parts store like Advance or Napa and see if you can get a weld on exhaust flange about the same size. That could be machined down to give you what you need if you use two gaskets. You weren't clear as to which way the manifold was off, up or down. You really have to watch what you buy for these replacement manifolds. I was at a tractor show and there was an H with a "Generic" manifold. It had slots in the carb flange to take both the H carb and the 350 carbs, how stupid!

Don't have the old one to compare but I found a picture of the old one and it is a distillate and kerosene model

Dan I would contact the seller and ask him what you should do. If it is wrong he should replace it with one that is correct. Just make sure you contact him before you fire it up so you won't be stuck with one that won't work.

If I am not mistaken there is some adjustment for leveling that tube at the governor end. Loosen the 2 screws and it should possible to move that tube up or down a little to level it.

If the carburetor flange is to low I know of some that had the flange milled down to line up. Heck of a note after paying for a manifold. But if the head was milled a lot in the tractors life that could also be it. Maybe you already tried the tube adjustment at front. It may not move enough though. If the tube, carburetor or manifold is changed the governor link to tube shaft should be readjusted or checked.

Jack, all the replacement manifolds are made to fit either carburetor.

I agree with Jack. I as well purchased a manifold from a dealer for a Super H and had the same problem. The carb mount holes were slotted, apparently for different model carbs and the governor tube when assembled, angled down towards the carb. It looked so bad that I didn't leave it on long enough to see if it would work. The old manifold went back on and the new one got thrown under the bench where it still lays. It would be nice to know of a source for model specific manifolds as there apparently was a difference.

Guess its been 6 or 7 years since I ordered one. From the looks of the one I saw, I hope I never have to order one of the "new" replacements.
