maybe it's just because it's early morning here & i'm not seeing/thinking straight, but what are you asking? i understand you have a cracked cylinder but after that i'm lost.
Sam,
That piston will be -.005 clearance in a standard application.
You measure at the centerline of the pin for proper piston diamter.
That is incorrect ( for these pistons). TRW skirt design is different than many " modern" skirts. Every manufacter specs a different measurement location. TRW happnes to be from the centerline of the pin, down, just below the pin hole. Not the skirt.
If they are a coated TRW, then you go with a given bore dimension,provided by them, not an actual measurement.
