Is the finning any different on the center (hotter) cylinder ?
Doesn’t appear to be - just curious.

Yes, there is much less of it. Study the 3rd image.

Okay..... So a Japanese co-worker here at the hangar helped me with the translation .... but he used an App on his phone to do the translation, I believe it's because he's not a mechanic, or familiar with the Japanese used (many folks are like that here, not familiar with descriptive wording of things). Anyway, here it goes: Discrimination of the Top Ring Second ring. The second ring has an expanded ring inside, It is narrower than the top ring. the second is narrower MAA Expanding. Cj

Thank you!

I had to search all over the planet to find CAST pistons.
Those were the ONLY ones I could find anywhere.
They pass visual & dimensional inspection.
