Thanks!
But those value are only for the 192.982/192.985 , at least that is what it is told in my manual.
The 190.983 piston are smaller: 95.44 (for grade "0").
That is normal since the piston play of the 192.985 is 0.01 to 0.03 (I guess). For the 192.983 it is more 0.04 to 0.07. I have 0.09.

The problem is that New the play is 0.04-0.07. But theyre is no where mention of a wear limit... Someone knows what it is in % or value??
