Farmall A

Postby Tb20 » Sat Feb 01, 2020 7:39 pm

So I’ve made some progress with the A. But I’ve noticed an oil leak. It seems as it is coming from the governor housing out of the end of the shaft on the carb side. I know there is a seal in there but what puzzles me is it’s nice clean oil that’s leaking out and the crank case oil is not clean as I have not changed it yet... does the governor get its oil supply from the crank case??

The governor is lubricated from the crankcase. Are you sure the leaking oil hasn't dripped down from the fan hub?

i Hadn’t thought of that. Would make more sense now that I think of it.

Also had a leak at the rear of the machine. Took the cover off rite above the pto shaft, it was leaking at the bottom. There are 3 shins behind The plate. I assume it’s not sealing in between the shim plates.

There should only be shims there if you have a belt pulley attachment. If it is just a cover, there should be a gasket in place of the shims.

Must have been a belt pulley on it at one time. It’s just a cover now.

Gaskets are easy enough to make: roll of cork or oil-fiber gasket material, X-acto knife and a set of hole punches from Harbor Freight.

I just used my cordless right angle die grinder with a scotchbrite Roloc to clean them up. Degreased and used rtv

Has anyone successfully removed a steering arm (what I would call a pitman arm) without removing the axle? I’ve got not quite 180* of play in steering and I’ve checked it all out and I think all the bearings are good but the pitman arm it’s self moves up and down like it’s wollered out. The shaft it’s self is not moving from what I can tell. Idk if it’s the square one or the round but it does have the “clamp” bolt.

I’ve got the steering arm loose and dropped down but I cannot get it completely off the rod. Do you have to separate the gear box it’s self to get the shaft to move up far enough to get the arm off? I was hoping to leave it together on the tractor but the arm won’t clear the housing... or am I missing something here

Parts manual 26F is available at the Quick Links tab, top left corner of this page/pdf manuals/A, SA, etc. might help you see how it is installed.

It has been decades since I worked on those particular parts. Seems like it was possible to remove the arm without opening up the gear case. It may depend on which style arm you have. It may require cranking it all thew way to one side or the other to get it off. (I may just be remembering the need to crank it to one side to tighten the clamp bolt on the early style.)

I may have never done exactly what you are trying. I only remember doing 2 things to those parts:
1) Cranking it to one side to tighten the clamp bolt.
2) Tearing it completely apart to replace the clamp style shaft and arm with the late style.

It’s the clamp style and yes I had to crank it all the way to one side to get the bolt out but it doesn’t have quite enough room to drop all the way off it’s so close but the angle doesn’t seem to allow and I don’t want to split the case since it’s not necessary, as in not needing parts anyways and I’ve seen plenty of diagrams on assembly and the like but nothing on removal

I didn’t get it to drop all the way off like I had wanted it to but I cut some shins and put it back on and snugged it down. That removed almost all of my steering wheel play
