Piston stamping question

I have a couple of 702 v12,s that the piston is stamped cam 3032. What does that mean?

Re: Piston stamping question

It might just be a part number. See this Yamaha

Usually the oversize markings are like this "0.30" under or over the part number.

Re: Piston stamping question

the piston is stamped .020 and then it is stamped cam 0332, I posted 3032 that was wrong . I understand the .020, but can not figure out cam 0332. I will call a machine shop that worked on these back in the day. Bob
