Well, its not in a Z but you guys are 'experts' so I 'll give it a shot. I got this old tractor I'm restoring, and its stuck. Been stuck. Tried letting oil soaked in the cylinders. Tried pounding with a block and hammer on the pistons, tried Coke, tried water(some guy said this would work) now what should I try? Don't want to pull the crank, and pistons and sleeves will be replaced. Any ideas? Thanks.

You're restoring a tractor?

This is for hauling your Z to the track, right?

I would recommend you just get it over with, and pull the motor. You'll have to pull the motor to do all your trick performance mods on it anyways, so best to combine everything into one operation. I've never worked on a TRACTOR motor before, but you say these things are set up to pull the pistons with the crank in situ? That's a new one on me, but then, I've never met a farmer who isn't outstanding in his field. The crank is undoubtedly quite rugged, but I wouldn't suggest hammering on pistons as a means of finding out just how much so, and I suspect the older farmers would tell you the same thing.

I had an old '52 GMC truck with the same problem, I tried alot of what you already have done, what finally worked on it was alot of wd-40 in the cylinders and a long bar on the crank, tied about 50lbs hanging off of the bar and walked away, every few days I gave the bar a push and put in a little more wd-40. took awhile but finally did the trick. good luck!

We always used diesel fuel on the farm. Be liberal with it and give it time. Usually worked after a day or two of soaking.

I helped a guy restore a Massey Fergeson, and an old Case. Both had seized cylinders. Both enginers were sleeved. If you disconnect the connecting rods from the crank you might be able to pull everything(pistons,con-rods,sleeves) at once. The sleeves are connected at the deck. They did this so that the block tolerences didn't have to be very good. If you ask around you might be suprised on what's still available for those old things.

Tractors, Trucks, how about a boat... :)

I rebuilt a Ski Boat after it was left out in the weather for a few years. Same problem - I could turn the motor with a beam bolted to the flywheel, but no matter how long I let the cylinders soak they wouldn't come good.

After I tore it down I found that rainwater had got in the sump and seized one of the main bearings. Turns out the rings weren't seized at all.
