Piston marking: ID please
« on: September 07, 2011, 01:35:03 PM »
Can anyone tell me what this marking represents on the piston. It is a "3" with an arrow (or greater/lesser than sign) over the top of it.

I have them on 2 pistons, and the number is different. I can't seem to search what this represents.

Thanks

I'm not sure which holes you are talking about.  HondaMan mentioned that it might be a weight marking.  Not sure.

At this point, I'll measure it agin, but it seems that the two numbers being different would represent something weird.
