What goes in here??? (Farmall 140)

AL Farmall Boy · Aug 12, 2010

You are looking at a 1976 IH Farmall 140 tractor. This appears to be a "filler" spot on the governer. What is this for. Apparently it is for usual and regular engine maintence. The oil filler is directly on top of the hood, so it can't be that. Thanks for the help

you put oil into the engine through that cap, the thing on top sticking through the hood is the engine breather cap.

AL Farmall Boy · Aug 12, 2010

No, the oil goes through the hole on the top of the hood through the valve cover down to the head, etc. I am not sure what this filler cap/hole is for.

FC Andy · Aug 12, 2010

Well, if you think about it, it is all open between the governor and the oil pan, so I"d assume that you could fill the crankcase oil at this location. That being said, My C dosen"t have such a thing, And I"ve not seen that before, at least on A,B,C,SC, etc.

No there is no opening on top of the hood on a 140. The only way to get to the breather is to take the hood of. When they switch to the 140 model they didnt bring the breather up through the hood. So that opening you see is where the oil goes. Erik..

It is the oil filler. Every 140 and several other models from that age forward have it there. I guess you could pull the hood off so you can add oil through the breather cap. But it seems like using the oil filler on the governor would be more convenient.

AL Tractor Pickers · Aug 12, 2010

My mistake, my mistake. I was going off of the valve cover because it has the filler hole on it and assumed it stuck out of the hood. I went over to my other 2 140's and noticed that they didn't have a hole on the top and had the side fill hole. I was confused because the old valve cover (we replaced with one from Farmall 100) had the hole, but is shorter to fit under the hood. Now it all makes sense. We'll just have to saw the taller spout off of the Farmall 100 valve cover so it will fit under the hood like the original. Thanks for explaining all of that guys!!!

Now, the breather actually goes through the hood; but the oil filler tube doesn't.

Bus Driver · Aug 12, 2010

Al, on my 140, the crank pulley is so close to the casting beneath that the belt is almost impossible to change. Is yours that tight?

IH fan · Aug 12, 2010

When I bought my 240U, there was a hole in the hood above the breather. The guy I bought it from said he couldn't figure where to put the oil without taking the hood off, so he drilled one there and put a plug in it. Later he found the correct filler like shown in the picture, but it was hard to see with the loader in the way.

James K · Aug 12, 2010

your supposed to fill that with oil, when i was restoring mine it was full of oil and there is no way for the oil in the engine to get to the govenor.

This thread has gotten so interesting I had to get my TC-52B Parts Catalog out to see what was going on. This catalog is for Farmall and International 100, 130 and 140 series tractors. In the engine section it shows a change at C-123 S/N 65001 and up. I think that since this manual covers several different tractor models and with the C-123 notation it must be referring to the engine s/n and not the chassis no. Prior to s/n 65001 the oil filler and breather cap is located through a cutout in the hood with a different part no. noted. At C-123 s/n 65001 and up a different governor variation is used which lists an oil filler cap as one of it's components and is shown in the same location as in the photo attached to this thread. I just don't recall the configuration of my 1965 Farmall 140 but will certainly know tomorrow but I don't recall a breather cap visible above the hood. My 140 unit s/n is below the 65001 change over point while the engine s/n is higher then 65001 so will know tomorrow on this after seeing my tractor and taking note of it's different components. This has certainly been a learning session and I try and use these to increase my IHC knowledge of the variations on my Farmalls. This has certainly been an interesting and informative thread and thanks to all the informative comments provided for us to share, Hal.

C-123 engine serial number 65001 was the start point for engines set up for the 140 and 240 tractors. Serials below that were in the 130/230 and earlier models. If you keep flipping through the parts catalog, you will find other changes effective at 65001 (water pump for example).

NawlensGator · Aug 13, 2010

Both my '68 and '72 140's have that same oil filler cap which is where I add engine oil. The three holes in the hood are (front to back) for the radiator cap, muffler, and the air breather tube.

Farmallhal · Aug 13, 2010

I looked at my 1965 Farmall 140 today which carries a chassis s/n of 307xx and it has the oil filler on the governor with no hole in the hood for a breather. It agrees with the parts catalog I noted last evening. Jim Becker has this right in my opinion (I never doubt him anyway) as the changes where made to accomodate changes being incorporated on the first 140's produced. I didn't take time to go through the entire part catalog but as Jim suggested I believe I would find other changes as well at C123 engine s/n 65001 and up. Hope this helps in this mystery and confusion, Hal.

AL Tractor Pickers · Aug 13, 2010

Here is a picture of my 1966 Farmall 140 (chassis serial #31665), and you can see that it has the breather coming out through the hood. I bought this tractor from the original owner and it looks to be all original. I am in the middle of painting the tractor, and the hood has already been painted. I also have a 140 (chassis serial #8930) which is older than the other one, and it has the same exact set up. I am certain that it is in original condition because I know the man who has owned it since new.

I am going to post pictures of each in the order I have them listed.

Let me try again.....

IH fan · Aug 13, 2010

It would appear some people here are confusing the air filter with the crankcase breather.

TheDurk · Aug 13, 2010

(quoted from post at 00:11:55 08/14/10) It would appear some people here are confusing the air filter with the crankcase breather.

Exactly. Look up under the hood on either tractor and you will see the crankcase breather in the middle of the valve cover, a little smaller than a baseball and completely covered by the hood. That is connected to the engine. The airbreather that goes through the hood goes to the air filter and then the carburetor.

vidently the same people that were going to fill the crankcase through it.

Farmallhal · Aug 14, 2010

After looking at your photos it is evident this is just a nomenclature or description problem. What the majority of folks on this thread are referring too is the crankcase oil breather which is used on some models as the engine oil fill as well. What you are referring too as the breather is actually called the oil bath air cleaner which does have a hood penetration. Most of the folks on this thread were referring too the oil breather for crankcase ventilation and oil fill on the C-123 engines prior to the 140 being introduced which was located in the center of the hood. Your 140's look exactly like mine above the hood. This thread started when someone wanted to know what the cap on the governor was used for and as we developed through this thread determined it was the new engine oil fill on the 140's. Hope this clears this matter up for you, Hal.

AL Tractor Pickers · Aug 14, 2010

Thanks so much guys. I knew that was the Air Cleaner coming out of the hood. I have always referred to those as the "breather". I've never really heard the oil fill spot referred to as a breather, so I was confused. I thought you guys were talking about the air cleaner coming out of the hood. HAHA, no I wasn't going to fill the engine with oil through the breather. I've got more sense than that. Thanks for all the help!!
