Case IH 2294 Tractor

bobrobert58 · Feb 5, 2019

I have a 2294 that I use in my farming operation. I have been told by a Case IH service tech that the differential lock should always be engaged when the tractor is used in any field operation and not doing so will destroy the spider gears in the rear end. I have used the tractor for several years for light duty work (planting and pulling a sprayer) with out worrying about the diff. lock being engaged. Is his statement correct?

Well if that is true then I have been doing it wrong for almost 40 years. I only use the diff lock on my 2090 when I am in a situation where I think it will help traction. I'd say 99% of it's 8000 plus hours have been without the diff lock engaged.
First time I have ever heard that theory.

Pretty hard to turn around on the end with diff lock engaged don't you think?

Diff lock automatically dis-engages when you hit either brake pedal.

I have rarely used a diff lock, only when it might help with traction and that is rare. If you are getting a lot of spin on one side for some reason his theory might hold some water, otherwise I don't see how it would make much difference. Those don't have a lot of rear end problems anyway. Are you using real case hytran in the trany? If not you should. That will make a difference.

It was news to me as well and I'm not sure I agree with his recommendation. In the past I have only used it when using hard pulling tillage tools. I have a Trimble Auto Steer on it that I use when spraying and I think the diff. lock and Trimble would be fighting each other. He feels that I've damaged the spider gears and of course is recommended that the rear end be opened up for inspection. Could he be "mining" some business??

The only significant thing to remember about a Dif lock is to not engage it when a wheel is spinning.

bobrobert58 · Feb 5, 2019

Just a few additions for clarity. When I do use the diff. lock I bump the brakes and turn it off before turning on the ends...obesely. This all started when I took the tractor in for another issue and they came up with the idea of needing to "open it up" for inspection. I have never had any problem, that I was aware of with it in the past.

Why does he think that? Have you got a noose or vibration issue?

JD Seller · Feb 5, 2019

I would say he is trying to baffle you with BS to make money off you. I would be looking for another mechanic.

I have bought, sold, and traded a fair amount of Case tractors of that vintage, 90 and 94 series. They did not have rear end issues unless they where really abused.

Rugged tractors that I always thought where kind of clumsy. There value is really dropping when compared to others of the same age and size.

I would ask him to show you where the manufacturer has put that in writing.

bobrobert58 · Feb 5, 2019

He thinks it has a "clunking" noise when turning, I've never noticed any.

find a different service tech

Hi bobrobert58

Get him to actually drive this tractor so you can hear this clunking. if you've got a mechanically inclined friend take him along and don't introduce him as your mechanically inclined friend and see what he thinks. If your doctor told you you'd be dead in a week you'd be looking for a second opinion. If you don't trust the mechanics you have working on it your tractors no different than you.

is this guy younger than the tractor, as it's getting hard to find guys that know those older tractors in dealerships and unless the "computer" tells them anything most of them are glorified parts swappers, that come out of school now.

I'm 44 and trained when there was hardly any computers on some tractors in the early 90's, a customers friend told him after talking to me and watching what I was doing, "that guys a lot more of an old school mechanic" than just a parts swapper !

Agree with Marloweg. In my mind you should never use it unless needed. You want that differential to be able to operate/adjust, whatever term you want to apply. Otherwise you are putting a lot of strain on that rear end.

The same for 4wd, in my opinion you should only use it when needed. I won't give the detailed examples of why I feel this way, but the tire technology has gotten so good and then you add duals, sometimes in the front also, that the strain on the driveline is really high, especially when turning. It is like when your truck is in 4wd and you are turning on blacktop. Again, my opinion.

When I plow with my JD 4250 the only time I use the differential lock is if I get in tough going, usually a wet spot. Then I have tap the brake to turn.

The earlier CASE models 2090/2290 had problems with differentials.There was a massive rework on those differentials to upgrade the spider gear thrusts and bushings plus bigger and better side thrusts washers for the differential carrier. The original differentials had to be taken to a machine shop to allow for the thicker oil impregnated thrust washers. The spiders were conical on the outside and also new harder pins were installed.
Your tractor has all those updates and more. The 2290/94 made far more power than advertised and if a farmer weighted the crap out of the tractor so it could not spin a bit, he would have differential problems.
Ideally, you want about 5% slippage and pull your tillage equipment at 5mph plus.
The only situation where a diff lock would need to be used for a tillage operation, would be if you are moldboard plowing with a in-furrow plow, and the LH land wheel is spinning a lot.
I am a former Case dealer and went thru that whole rework scenario on way too many tractors..

In 1979 I had one of the early 2390 Case tractors...A couple of years later the rear end destroyed itself with the problems you mentioned...At that time Case recalled all the 90 series...They stood a nearly $20,000 bill on my tractor as it had even broke the $4500 rear end housing..There was a scoop shovel full of metal shavings in the rear end and the tractor was still moving..

While your on this subject, I have a 1394 that clutch nor pto will go in gear. It was brought here that way, its a nice tractor and I'm wondering what the problem is, and is it worth fixing, cuz it looks like cab has to come off to split. I'm sorry for jumping in on your subject, but saw a good opportunity to ask about this tractor.
