Is it possible to install 3 1/2 inch power crater sleeves and pistons in a straight H engine? (Like the Super H) I'm also wondering if the crankshaft rod journal sizes would be the same. The tractor I'm working on now has 3 7/16 inch power crater pistons in it but look pretty well worn. The owner wants more power!!!

If you want to run the Super H pistons youll have to bore the block to except that sleeve. You can run sleeve less, however i would not recommend this, with this its pretty much a one shot deal. Personally i would stick with the 3 7/16". Are you building a puller, worker or just play?

Thanks Andrew. He has a loader on it and uses it on an acreage to plow snow, cut wood, etc. Kind of a nice tractor, power steering, wide front end, live hydraulics, etc. Just uses a lot of oil! I'll pull the pan tomorrow and see what the cylinders look like, but guess I'll have to install new sleeves. I can look down to the top of the pistons and see the top ring pretty easily!!! Thanks again. I'll stick with the 3 7/16's
If you are unsure of the tractor"s history, you"d best measure the bore of the sleeve, the bore of the block with sleeve removed, and the piston diameter. Who knows what a previous owner could have modified or goofed up already? Putting H sleeves into a block modified for Super H parts would be catastrophic if assembled and ran. When measuring, you may find the wrong combination of parts in there if someone was really sloppy in their work or plain stupid.
by the way, you never replace just the sleeves or pistons--they are a package deal. Not that it hasn"t been done or a rare situation might warrant one and not the other. Usually a worn engine is renewed with piston and sleeve assemblies. Sometimes a new set of rings is installed in the old piston and sleeve. But usually when these engines are torn down, they need new everything because of the wear or damage.
When you have it apart, fix it right so you never have to have it apart til it"s worn out and old again.
Again, measure everything if you aren"t sure. Measure if you think you are

If the engine is worn that badly, it is way down on power also, so doing a complete rebuild with the 3 7/16" sleeves and pistons will result in a whole bunch of increased power and performance.
