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? |

Rod Balancing, End-to-end. I also wondered how in the hell do you balance END-TO-END.
I found this 20 minute video (balance at 6 minutes) where he hangs one end on a nail and puts the other end on the scale.... weighs each rod and compares, removes material, repeats.... is that the way to do it? Good way, Bad Way??? This link and the embedded vid starts at 6 minutes. https://youtu.be/U3IXSywgTnM?t=386 https://www.youtube.com/watch?v=U3IXSywgTnM?t=386 |
