I am gonna make a 2 liter from my 1.8. So I have a refreshed 71mm crank that I have been told has been ground to -0.010.
I measured as best as I can with a digital mic and got about 59.66 on the mains and 49.65 on the rod journals. Where can I find the STD specs and ranges ? were they 60 and 50, respectively? Since I know nothing about this crank, how can I verify the 71 mm measurement? |

How about the 71mm measurement? Not that it matters, just curious if I could measure that.
THe rod journals are smaller, but otherwise it looks just like the 66mm from the 1.8. I thought the rod journals were smaller and offset. seems like 5mm offset would be visible. Any other way to tell it's a 71mm? Markings, etc... |
