are kenig hi comp.pistons any good ??

Hi,

Piston pin to piston clearance is 0,000 to 0,012. If clearance is more then 0,05 mm, repair.
If you can move the pin freely through the piston when cold, suspect and measure the clearance.

In plain English, when you feel (side) play, throw it away, because it's hard to feel 0,012 mm.
And to give an answer on the question, no, you don't need to move the pin freely to the piston, it's a tight fit, depending on the tolerances on both piston and pin.

Ya mean the pin Doesn't Rotate In The Piston!!!!!!!!!!!!!!!!!!!!!???????????????
Now ya Got It. .............lm

Hi,

No, the piston isn't part of a bearing. The bearing is a combination of conrod (small end) and pin, not piston and piston pin. But when the piston is warm, there is a possibility that the pin can rotate a little in the piston, but not as a bearing.
