Whats going on here?

I posted earlier on the RP pistons. Is this correct? Do all the domes run crooked compared to the edge of the block? #1 is relaay off.

Any ideas?

If the problem is the rod, replace it and follow the advice you had earlier about checking for head clearance. My gut feeling is that the small amount of twist you see to the tops is alright if it is consistant. Your 140 head has the small combustion chanber so if you are at all concerned, definately test for clearance.

If the problem stays with the piston, I would send them back to the supplier/manufacturer.

Just a note, I don"t ever recommend saving the pin bushings when you replace the sleeves and pistons. And Hugh, that is definately the later 140/240 series block as you can see from the flat in the lower left picture. Count his head bolt positions... Just a gentle reminder that the I&T manual has an error.

In all my many years of tractors and the engine rebuilds that comes with it, only twice did I buy aftermarket, and neither piston-sleeve kit had endurance. Probably bought a dozen or more kits from manufacturers and all were good.

Bear in mind, I haven't done an engine in a few years. I have a gut feeling CaseIH now treat these old Farmalls as after market, quite possibly it's all junk.

If you can't return them, it looks like your choices are run them or buy another set. I'll spare you my opinion on aftermarket parts.
