Have an old IH 56 HP tractor. Have read that it must be split to work on the transmission etc.
Just curious, anyone have photo(s) of a split tractor?

Walk through any dealer shop and you should see a tractor or two split in there. I guess if you want to see a pic of it you aren't familiar with it then??
Basically, when you 'split' a tractor you seperate the engine and front bolster half from the transmission and rear end half of the tractor at the bell housing. You have to have supports to hold up the rear end of the engine (and keep it from tipping over since it pivots at the center of the front axle) and supports to hold up the front end of the transmission. Once you have all your supports in place (and preferably bolted up) you take the bolts out holding the engine to the bellhousing and then gently work the two halves apart. "Gently" is relatively speaking since you're working with two chunks of iron connected by at least one shaft (in the clutch disk) and usually two (for live PTO's) and they don't have much play in them. Plus both chunks usually weigh from several hundred to several thousand pounds so it's something you generally want to do in a concrete floored shop and with good, strong, ADJUSTABLE supports. I've seen guys just cobble together a stack of boards and cinder blocks but it will mash you THROUGH the floor if it tips off!
The REAL hard part comes in lining the two halves back up and 'stabbing' them back together again. You have to make sure the clutch disk has been lined up properly with an alignment tool and then line the splines up in the tranny shaft with the clutch disk splines. Usually there is at least one other shaft in there to line up with a coupling for the live PTO and sometimes for hydraulic pumps and other things. Everything has to be lined up at once and virtually perfectly to get them to go back together again. Usually takes at LEAST two guys or one guy working FOREVER. It's a gentle operation that can't be forced (without breaking something) and usually hangs up about a half inch or inch from being done for 'no apparent reason' that you can't see and usually that last half inch is the hardest part of the job and ends up taking three times as long as the rest of the process. Once they're together right, then you bolt everything back together and remove the supports.
Not a job for the faint of heart! We used to split 656 IH's and a 1056 IH one time in the ag shop but it was a BIG job! We had I-beams with plates welded to them that bolted onto the loader mounts on the tractor sides and had big leveling screws welded onto the ends of the beams on sorta jack-stand things. The engine half had a similar beam with HD shop roller wheels on the ends and a set of brackets to bolt on to the engine so it could be wheeled away. We also had a BIG HD A-frame hoist on HD shop rollers to help lift/lower everything into alignment to split and stab them but it was STILL a big big job! Good luck! OL JR

Get a repair manual for that tractor , I have them for most of my tractors , Tractor supply should have them. that will explain what has to be done . It should also give you measurements to make a tool to line up the clutch if you don't have one.
