Here you have the specifications directly from the BMW TIS (Technical Information System)
Sorry, i only have this available in German, but if you spend just a few minutes with it i'm sur you will be able to identify what you need.
But here you have some translations:
General:
* Stufe 1 = First oversize
* Gelb = Yellow
* Grün = Green
* Weiss = White
* Kurbelwelle = Crankshaft
* Lager = Bearing
* Spiel = Play
(Kurbelwellenlagerspiel = Crankshaft bearing play)
Img 2:
* Kurbelwellenführungslager = Crankshaft guidebearing
* Pleul = Connecting rod
Img 3:
* Kolben= Piston
I hope this helps you!
