Get the pistons out of block first. You can have block bore and sleeves installed back to stock. Talk to a good machine shop in your area that KNOWS what he's doing.

You are talking about outside the block, not the bottom of the cylinder?
Head and block can be welded. You might check on another block and head also.

Yes outside of block a couple of hair line cracks Im sure someone failed to drain the water an it froze.I dont know history of tractor.But mostly looks good havent used micrometer on anything yet Just trying to see if it is workable.Has been setting for many years.

I have 2 blocks, one with pistons and rods in Minnesota. Will sell reasonable. Ron MN
