So I know Iame x30 replacement piston set are labelled on box with actual bore size not piston size.
What is actual piston size? I have seen to different set of descriptions online one with .08mm difference and one .11mm difference.
I took notes last time I ordered a 54.0 V or green replacement piston but I cant find my notes anywhere.
Let me know thanks.
I have some ideas, but don’t want to assume. @Ryon_Beachner, what’s the skinny on X30 pistons?
@Jamie_Gonzalez this is directly from IAME USA East website under the tech documents.
"Play between piston and liner must be
0.11 ÷ 0.12mm. If play is higher than 0.14mm replace piston.
Pistons are measured at 17.5mm from bottom.
Size of liner to be matched with piston is marked on
top of piston with a green or red dot or with letter V or
If the size on piston top is marked with:
-a green dot or letter V: add 0.01mm to size marked
on the piston to match the liner size.
-a red dot or letter R: add 0.02 mm to size
marked on the piston to match the liner size."
I hope this helps. Attached is the link to the overhaul manual directly from IAME.
Not exactly what I am looking for.
What I am trying to confirm is the piston size.
For example if I purchase a 54.0v is the piston in the box 53.92 or 53.89?
I found some info online that indicates replacement piston are .08 smaller than box size/piston top and another states .11
