I searched to see if I could find something on this but my search skills stink so pardon me if I'm being redundant. I am at the point with my 75 R90S rebuild where I need to do main & rod bearings. For guidance I go to the factory manual I have and it tells me the crank journals are a nominal 60 mm. But then they tell me that this is 2.34" nominal. I get really confused because my journals are miking at 2.36 something. Then I realize that somebody in Bavaria must had a couple too many dunklebeirs when they did the math 60mm IS 2.36 nominal. So I ask my dealer for the information to size the bearings and they send me the very same (WRONG) info.
Now despite the obvious math problems above, I have a question for the technical cognoscenti;
One document says crankshaft radial play should be 0.035 - 0.065mm (.0013 - .0025") the other says 0.020 - 0.065mm (.0008 -.0025")...... Who should I believe?
