I am splitting a 2290 case to fix the powershift. The split is between the engine and torque tube. Bolts are all out, stands are in place and set. According to the book the next step is to roll the front end of the tractor away from the back. This is a great idea but it doesn't work. Any other tractor I have split just kind of came apart. It was supposedly split at a shop four years ago.

Any tips or idea on how to get this thing into only two pieces?

Thanks.

Make sure to wedge some 2 by fours or something in the front axle so it cant tip from side to side on you...then I would maybe try to jack it up at the split with a bottle jack to break the gasket...once its split make sure to pull out the lube tubes for the powershift...I think there is two at the top of the trans at the front and 3 short ones under the valve body on the side(have to pull the valve body) they are threaded with o rings on them, just screw a bolt into them and pop them out.

If its still stuck after the gasket is free, must be one of the shafts hanging up somehow in the flywheel or torque limiter in which case you just have to make sure everything is square and straight and wiggle jiggle pry carefully till it lets loose.

Thanks. I have been wondering if it could be the gaskets. I did not have the nerve to give it a good working over to get the gaskets to break free. The starter was removed so I could turn the flywheel on the odd chance it was binding but that did not help.

I have some blocks pounded into the front end on the axle so there is no chance of it going over from that.

The older I get the more cautious I get. When I was younger the tractor would have been propped up on a jack all jack sitting on a skateboard.

So..... Idiot of the day award goes to me, I am #1.

The official case service book showed four vertical bolts on each side of the block. I saw four vertical bolts on the side of the block and removed them. Somehow I am fortunate enough to own a tractor that some MF'er (not massey ferguson) decided it was a good idea to add two more bolts tying the thing together which are stuck up under the cab. You can just barely see them if you know where to look. One came out. I built a "wrench" to get at the other one but it only rotated far enough to break it loose, can't get another grip on it. apparently I am lifting the cab or getting an angle air wrench now.

Thanks for the help and apologies for my lack of brain power on this one.

Glad you got it. Everyone else probably had better advice than what I was going to suggest........ a cutting torch.

Anytime you start contemplating cutting torches and sledgehammers it is a better idea to sit down, have a coffee and relax for a few minutes. There is a reason I have this knowledge; :11: was usually the end result. I do appreciate the suggestion though. ;)

I am also realizing that when building stands you are not holding up the left side of the planet and don't have to build them as such.

I've had a few over the years that hung up in one way or another, been more than once I've seen splined input shafts wore to the point they were locked with the discs and you had to rock things and screw around to get them to part ways. Once had to undo the pressure plate bolts from an inspection hole even and let the clutch go with the tranny as the clutch disc was seized to the shaft.

Coming apart hard is one thing, but the way some guys force them back together just makes me cringe. Have seen damaged seals, broken blocks and clutch housings as result of them trying to use bolts to pull it together when all it needed was to be properly aligned.

And yes, I have missed the odd bolt here and there myself as well lol now and then there will be some inside the housing, those can bite ya if you don't have the book

Once ALL the bolts were out it came apart like nothing. Now I am back on the internet looking up "how to disconnect a terminal block without breaking it." I re-wired a combine after a fire a couple of years ago and I think that traumatized me on the electrical stuff.

Another thing that I have learned is that the front end rolls a lot better when the tires both have the right amount of air in them.

With my less than professional mechanical talents I have become quite adept at discerning the importance of leftover parts by looking at them. :)

You are doing great: I helped a friend change frames between two semi tractors one time, and we could not pull that frame out no way, no how... until we figured out we had missed a bolt. So don't feel bad.
The very first time we split a tractor, immediately after we had rolled it apart, a friend dropped in and told us we were crazy: he and his brother had split a small tractor years earlier and thought they were never going to get it back together, so he thought we would never get that much-bigger tractor put back together again.
But it worked great, just like your project is going to as well.

The guy who designed the electrical connector won, it is still there. I did come in second though, the wire is long enough that I got away with not disconnecting it; as a consolation prize it is a good place to hang the trouble light.

For anyone doing this job in the future I have a suggestion: In the book it says to put a 3/8ths bolt down to pull the plugs out from the top. That is what I did. The bolt went in quite smoothly. So smooth in-fact that the massey ferguson-er went right to the bottom and hung there. I grabbed my magnetic pickup tool but due to the placement of the tubes it was like you and a woman lying on your backs beside each-other and trying to have sex. After more tool and vocabulary building the bolt was retrieved. The lesson here is that putting a 7/16ths bolt down the hole gives far superior results.

Another thing to keep in mind is that the tube covers require a 1-1/4 flat wrench. The factory torque is 376,874.82 foot pounds, so have some heavy persuasion tools handy.

You will also need three 1/4x1-1/2 full thread bolts to do this job. Like me you are probably thinking "I have 10,000 of those, that is not a problem." But if you are like me you will have 9,999 of them that are not full thread.
