Title: Rebuild: Tolerance questions
Post by: badboypolar on February 01, 2007, 01:02:50 PM

So I've looked in two bentleys and found nothing as to what the tolerances of some parts.

1) piston space from wall

2) all crank tolerances (rods, main bearings, play)

Thanks guys.

I have the PDF version one. Where are the specs, cause I've look through all 800 pages and I must be blind.

Thanks for the help guys.

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!

Funny cause I looked in the TIS and could not find this.
