Piston sizes above shown with decimal point indicate actual marking (and size) of Mahle piston. Sizes shown with comma are the catalog listing size and tend to be the bore size required for piston. Never pre plan for a piston size. Always have your piston in hand before you do any machine work!

Always have your piston before starting machine work.If you have more or better data than what I have done here please send me a copy and I will share it with all Husky owners on the net .Thanks
