My brother and I are looking at pulling the engine form his 550 today, and we're wondering what's all gotta be done prior to pulling it out.

Does it have a straight shaft to the flywheel like the 4 digit models? How do you get it out on the 550? We got the loader frame off earlier this week to make it easier, but we don't have a shop manual for it yet. It's on the list of things to get.

Allright thanks guys!

We worked on it today and got it out. He already had the sheet metal removed when I got over there, so I helper him drain the radiator and remove the tank and a couple other things. We put a jack under the transmission housing,and put the engine hoist on the lifting bolt on the head.

Took out all the bolts and left the 4 bolts to the frame in, but backed out 1/2" and then with him on one side and me on the other, we rocked the tires back & forth till it wiggled off the dowel pins. Took the bolts out the rest of the way and it pulled right apart.

Set the frame down on 2 jackstands, pulled out the 4 bolts holding the engine to the frame and then lifted it out, after putting a stand under the very front of the frame to keep it from tipping up & over.

Got the engine out of the way, bolted the frame back to the transmission, and then removed the pressure plate & flywheel and bolted it to the stand. Had everything from when I mounted my 1600's engine to the same stand, so it mounted right on using the same bolts and extensions I used.

That's all the farther it is right now, so now we've gotta start assessing what's al;l gotta be done to the rest of the tractor. The engine had the top end rebuilt, but it needs to have the new crankshaft installed. The clutch disk is covered in oil/grease so we've gotta figure out where that came from.

I did ntice the input shafts going to the transmission seemed to have quite a bit of play- are they supposed to be that sloppy? Could gear oil be coming out between the 2 shafts and getting on the clutch? The pilot bearing and the other one both need to be replaced, but the pressure plate and flywheel don't have any kind of grooves worn in them. Just greasy.

I forgot. I would convert both ends of the crank to lip seals if you can find the parts. Does it have power steering? I would get rid of the generator pump if possiable. J.

Nope, Armstrong steering. I will pass along the information to my brother on the seals, but I'm pretty sure that Tesch Bros. will just sell us the newer lip seals anyway.

Atleast that's what they did with my 1600...

I went to a few of the well known Oliver parts sites out there and got a generic list of stuff that should and needs to be replaced (wiring harness, seat rebuild, new socket caps, lights, steering wheel, brake parts, etc. etc....) and I came up with somewhere around $1000 for my brother to spend on stuff so far.... I know it's easier to spend his money than mine, but....

We'll give Tesch a call and have them price out a bunch of stuff. 99% of the time they can match or beat the online guys, and they use the same sources on some of the parts and we don't have to pay shipping that way. They're well aware of Korves and do business with them as well.

Now we've gotta find a good parts and service manual. The one on ebay right now is a little too rich for our blood though. Last time I looked it was over $160 for the 550 service manual.

Don,First remove the hood and the front radiator cowl.Then remove the radiator and the fuel tank.Take your oil pressure lines off.Block up the center housing on the tractor with blocks or a jack stand.Then support the front frame and remove the front axle center pivot pin.Then remove the four bolts holding the engine to the frame.Then you have four bolts holding the front frame to the center housing.Remove those and lower the frame to the floor.Then remove the battery and the tray and all sheilds.Remove the starter and tachometer cable.Remove the generator or alternator and lay it and all wiring out of the way.All the trottle linkage and related items should be disconnected.There is a stud located near the center of the engine between the exhaust manifold and the rocker cover.Attach a "eye bolt or eye hook"to this stud.Then hook an engine hoist to this point to lift the engine.remove the rest of the bolts from the center housing and pull the engine forward and out of the tractor.This is the way i've pulled them in the past and it worked very well.I imagine you could roll the front end away without dropping the axle but i have not tried that.The engine frame is quite heavy so be careful.The pto shaft stays in the tractor on this one.Be sure to block both sides of the rear wheels.Not a bad job that will go fairly quick.Good luck.

It's not difficult. I did one about 2 years ago by myself. It wasn't bad splitting the entire tractor first. You'll have to remove the obvious parts in the way. Support the trans and rearend. I used an engine hoist to support the engine and front end. Unbolt the motor from the trans, slide it forward away from the rearend. After it's split then support the center frame and remove the frame and front of the tractor off the engine. I didn't get my IT manual until after I got the motor back from the rebuilder so I knew what my torque specs should be. Take your time and pay attention. It's easy. Gary

They call it a "Z-split"- I'm not looking at the tractor right now, but you remove hood, fuel tank, various other stuff thats in the way, then suspend the front portion with a sling from above (so the front bolster doesn't just flop over and drop the front half to the ground when its unbolted), and jack up the back half with a floor jack. You unbolt the top half of the bell housing, then back down each side to the front of the transmission, then down. Hard to explain, sorry. Get an IT manual- it tells you everything you need, at your level of experience and savvy. You don't have to do anything about the PTO shaft- its just splined to the flywheel, inside the hollow transmission input shaft, and comes out when you pull the two halves apart.

You are either going have to split it or remove the upper clutch housing, etc.The PTO shaft is not a long shaft and the PTO drive shaft is splined to the clutch pressure plate. The clutch shaft is inside the PTO shaft and of course the pilot bearing is located in the flywheel. So it is not a straight out lift the engine up. Me I wouls split it. I would also take two plain Jane automotive jack stands take the tops out and fab an adjustable one out of say inch redi rod and fine thread rod would be better. More details later. We only did a few of them, this is not big utility tractor country. J.

It's been well over 35 years since I had one of those out Don,but I don't remember pulling the PTO out. I think I just blocked it up in the middle and unbolted everything that was obvious.
