Farmall 140 4th gear trouble

We have 2 farmall 140s, later models with the international decals, probably late 60s-70s model. Both of them want to pop out of 4th gear going down hill with a load. One is bad enough to where it pops out with just an empty 20ft flat hay wagon on the back, while the other is alright until there is something like 2 empty flats or around that weight. They both wine quite a bit in all gears, but esp 4th. I have never had them apart. They both will top out at around 14 mph. I understand that this means they have the optional high road gear. What would cause the tractor to jump out of gear and wine a lot in most any gear, varies with the load and whether it is pushing or pulling the tractor. Thanks for the help. I am thinking these tractors might be worth fixing up. One is in good shape but needs this and a motor overhaul, while the other has had the front end welded, needs brakes, but has a good motor. Both have fairly new heads on them. Thanks in advance.

You either have worn shifter forks or the gears themselves are worn. Don't know about the 140, but the A/Super A has square cut gears that are inherently noisy. The forks can be built up -- I've never done it, but all you have to do to take a look is remove the cover, very easy.

Since this tractor has seen quite a bit of road use, which starts in third and is shifted on the fly into 4th, I am guessing the gears are worn. How hard would it be to fix and what am I looking at $$ wise? Thanks.

Hurst: That word greas should have been gears. My finger don't always keep up with my brain or vice versa. When I say finger I mean one.

Aw heck Hugh when I get on a roll I use one finger on each hand, my back space key has more wear than the others.

Hurst: I don't think it is the shift lever being worn, that really only affects shifting from one gear to another. You may have gear wear, and yes they are the same as the SA, 100 and 130, straight cut gears.

I had this same problem with my 130, popping out of gear. I took the top cover off and the cogs were in excellent shape. There are detent balls in the shifter slides, that hold the transmission in each and every gear. New balls and springs cured my tractor. I think you should catch this quickly as popping out of gear will in time wear the greas themselves. Those springs and balls are still available from CaseIH.

Hugh, How much wear is tolerant on the gears? I will be home middle of next week and can take a look at it. Also, how much on the shifter forks? Is process of elimination the only real way to tell if it is the detent balls and springs? Thanks

Hurst: Once you have the top cover off, you can see most of the gears. In mine the teeth were nice and square, no pitting or corners off. Even before you take the cover off, you can feel the resistance of the detent balls when you remove it from each gear. Tie the clutch pedal down so you don't get resistance from gear mesh. By the amount of resistance you will quickly see the difference in the various gears. In your case you know 4th is bad, thus compare that with 1st, 2nd, 3rd and reverse. In my case 1st was the bad one, my 130 would pop out of 1st under heavy load. I have heard of these getting bad enough, if your on a steep incline, the weight of the shift lever will take it out of gear as you depress the clutch.

The 140s we have only pop out when you are going down hill. Could detents do this too? Thanks for the help so far.

Hurst: One principle I've learned in my many years around tractors and equipment is you try the most economical and easy anyalsis first. You do as I suggested in my last post, then you tell me what you think.

Certainly, going down hill in 4th gear is exactly where this could happen. That gear shift lever is top heavy, and if detent balls are gone, sure it can flop ahead. Those detent balls are in that top cover thus a very easy fix. I might also add if this has been going on for some time you may well have gear damage. Once you take that top cover off you can see the gears, again you tell me what you see.

So the forks usually don't wear as they do on the H,M, etc? -- I have a Super A, but only drove a B on the farm for one summer -- little experience with them as far as daily usage.

CNKS: It's ben my experience these don't wear the end of the shift levers or the forks as bad as the larger tractors. Then it's also been my experience even within the larger tractors, loader tractors wear these parts much faster than non loader tractors. This thinking is quite reasonable as a loader tractor probably has a 100 times the shifts of a non loader tractor.

I know my 300 always had a loader and we rebuilt that shift lever every 5 years. My 560 never saw loader work until it was 14 years old, and it was only after that the shift lever needed rebuilding.

One other thing I should have told Hurst about, once that transmission top cover is removed on SA, 100, 130 and 140, great care must be exercised getting the forks in right place as the top is put back.
