Son in law is going to look at one. I don't know anything about them except I was told by a hard core Case guy that they had some issues. SO what's the deal on em?

Thanks

They use only one torque limiter disk. If the tractor is going to be used for loader work with lots of clutching the disc can wear out quickly.

The limiter disc on the flywheel is a set tension non disengagable clutch and has nothing to do with stopping or starting the motion of the tractor, The lining wearing out is a very rare occourance but the spring centers are prone to failure, as were the 70 series. Being a set tension clutch it's purpose is to just move a bit under heavy shock loads but never "slip" per sae.

The actual clutching is done buy C2 clutch in the power shift and is very durable. Most powershift problems in any power shift tranny Case built were caused by sheared C2-C3 carried bolt or a disregard for maintanance causing sticky pilot spools.

They are a good tractor, but If I were not a Case man I would have a very good one check it out for you, If you had to rent a good Case Ag tractor tech for a couple hours it would be money well spent, and this goes for most purchases ,not just rtractors.

There is a general lack of understanding of the function of the powershift and it's interaction with the main hydraulic system that a good tech will have to ascertain the condition of the tractor.

As always Mel in dead on with his comments. Anorher point to research if the 2090 is an early Sn#, is whether it has had the extensive rearend differential upgrades installed in it. This will be a paper chase as there is no way to identify the rework from the outside, other than listening carefully while turning tight circles in both directions, watching and listening. for any binding or jerking. You can also jack up one rear wheel and rock it back and forth to check for excessive gear lash.

Loren, part of the update for the 20-2290 tractors included the addition of a ring+pinion lube line. This lube line is mounted on the trans cover top toward the back of course. It is difficult to see once the tractor is assembled, but is visible IF you know what your looking for. Add about 30 years of dirt and grime to the the top and its nearly impossible, but if a person is really determined it can be figured out if its there or not. Rod.

On the early models (I think the ones with the multi-colored tachometer) they had a keyed park loc gear that would sheer if put into park still rolling. Make sure park holds

I had some ring and pinion issues with mine as well as some main shaft bearing trouble. Never heard of the lube line and my dealer never mentioned it.
That aside I abused it somewhat unknowingly (20.8R38 duals and inner and outer wheat land weights on the rear). It didn't have enough slippage. If it's a short wheelbase it will ride rough. I twisted the smoke screw a little extra also. The brakes only have Two discs. I think I had sheared the teeth out of them three or four times. Especially with duals. Tom

I have driven one for ten years for a guy. If I still had my own place you couldn't give me one. Only good thing about them is the engine seems to work. It is a wonder my kidneys are still attached where they are supposed to be. Major problem is a weak transmission on them.
