Case 2290 PTO clutch issue?

Hi all, im hoping someone can shed some light on my situation…..

This is my first tractor, I’m a new farmer. I was brush hogging pasture and ran over a small remnant pile of hay. Turns out, that was a terrible idea and one I won’t soon repeat.

The slip clutches on the mower shafts didn’t slip and the tractor started to bog down a bit before I could jam the clutch and shut off the pto. During this there was a noise, hard to describe, (spinning/grinding….friction plates in the pto clutch maybe?) not sure. Unhooked the mower, the pto won’t turn on at all. Pull the engagement button up and nothing happens. Like, nothing. Can’t turn the pto shaft by hand with it on or off. The brake maybe? I never heard any big noises/bangs like a broken shaft might make……

I have the service manual and the parts manuals, but I have a few questions.

1. To remove the rear cover/PTO housing, will I need to drain all the hydraulic fluid? Will parking downhill help?
2. Where can I get the flow meter, pressure testing kit and clutch monitor without putting a second mortgage on my house? Do I need these things for any part of this particular job? Or would this be best left to the dealership?
3. Have I given enough information to go on that might point to a different problem?
4. Could this be a shear pin/key issue?
5. I have a fairly good mechanical aptitude and a small skid steer to help remove the cover rigging to the toplink pin. Any idea of the weight of the cover? Less than 1500lbs? 😬 skid steer lift capacity is 1400…
6. What might you do in this situation? Am I chasing my tail or heading in the right direction?
Are there any booby traps or things that would be helpful to know before I start exploratory surgery? I did read about the 5/8 studs to guide the cover out until it’s off the shaft, how long should these be?

Thanks in advance for any tips and suggestions!!

Hello kc…, welcome to YT! I would recommend you use the Contact Us below left in red and ask the moderators to move your post to the YT Case forum. Several of the more knowledgeable guys on that tractor don’t post outside of the Case forum. All I can add is were you running in 2 or 3 power shift? If you were when you hit the clutch and it shoved the PS back to PS 1 there is and additional jerk in the PTO shaft. I don’t know if that adds anything to your problem or not. This must have been a wider bat wing bush hog? All I know is that is one of the reasons my buddies family that had a 200 head dairy in the 80’s moved away from Case tractors. On a silage chopper if you were running in PS 3 and had to clutch under a fair pull on the PTO it would take out the shear bolts in the cutter.

Do the hydraulics work, power steering, brakes, and power shift?

If so, the live power shaft going back to the PTO is good at least to the middle of the tractor and probably what happened is that you tore up the PTO clutch plates, probably tore the splines out of the center of them.

You'll have to drain the oil.

I'm GUESSING the back cover/PTO unit weighs 1/3 to possibly 1/2 of the 1500 lbs. you are wondering about.

GOOD LUCK!

Hello, thanks for the reply! I requested my post be moved.
I believe I was in ps1 or ps2. Don’t remember which. I just remember clutching, jerking the throttle back and turning off the PTO in like three seconds or less. The tractor still runs and drives well, if that means anything.

Thanks again for the help! 🍻

Wore out, thanks for replying!
Yes, hydraulics, brakes, steering and power shift all work just fine. I found on step one in the manual where it said to drain the oil🤦🏼‍♂️
Looks like the skid steer will do alright to pull the cover and, hopefully it’s just the clutch plates. Probably ought to re o-ring and seal the pto while I have it apart.

You were dead on! Friction plates were trashed. The pto input shaft snapped off where it was cross drilled and went in the clutch hub bushing. Backing plates and retaining ring may or may not have had a short fight with ring gear in final drive. The center clutch hub and carrier took a little abuse (carrier shows a little marring where the backing plate and retaining ring sit. Wondering if they can be cleaned up.
I suppose it would make sense to reseal the clutch piston and brake piston while I’m in there. Any thoughts on the brake? Should I replace?

The carrier rotated smoothly and the pto shaft rotated smoothly. Does idler section need to be disassembled if everything seem alright?

Previous owner used some kind of grey caulk to seal the pto output shaft around the snap ring from leaking. It appears from the parts manual that there’s an oil seal that seats from the outside (ref#29 p/n: a140930) which wasn’t leaking, but there’s also a single oring inside to seal the putout shaft which may be the culprit. For transparency, the pto output shaft was set to deliver 540 rpm.


Any other “you should replace this while you’re in there” items that come to mind? Thanks again for your insight! 🍻
 
welcome to the wonderful world of farming and case tractors. Those pto clutch packs can be troublesome and also de laminate, causing grief. I do not remember those on a 90 series being too time consuming or difficult to rebuild. All I can say while there is check everything for de laminating clutch material. And sadly if you find any extensive delaminating clutches, In my experience the brakes were soon to follow. I am 100% sure that is not what you wanted to hear, but if the brakes are de laminating and depositing clutch material into your transmission, your transmission will be next, Just food for thought. A lot of local case tractors got auctioned off over the years after the owners discovered exactly what you discovered then discovered a brake delaminated then decided that a transmission was soon to follow and to the auction it went. Good luck.

Thanks Turbo, for the heads up! I delaminated the pto clutches when my slip clutches in my batwing didn’t slip. I did notice on the pto brake material that it was at a point that I wasn’t sure if it was delaminating, so I got a new one anyway. Good looking out! 🍻
