I have a Mahle piston that was supposed to be for a Stihl 026. It was obviously in the wrong box as the part number was correct for the 026. It's a 46 mm bore and 38mm tall on the edge. It's next to a 44 mm 026 piston for comparison. I'm thinking it's for a 028 super, but don't have one to compare. marks ver 008.jpg marks ver 007.jpg

I have an 028 piston. I'll get a pic to compare tonight. I think it might be an 028.

I say it's from an 034. Non super. Would make sense given the longer stroke in the 034. 028 is 42 or 44mm depending on the year. 028 super is 46mm and has a dome in the middle.
026 is actually more cc than 028

034 should be 46mm. I don't have one here for other dimensions though

I'm pretty confident now that it's a 034 piston. Thanks for all the help.
