Some people claim these cranks can't be ground because the hardened layer is too thin. Did the machinist test the hardness of the reground rod pin?
I just measured my own crank and found 0.0012" / 0.03mm runout. I was told by LN engineering to throw it away. It seems strange to me that the tolerance is that tight. The 944 crank has a tolerance of 0.0031" / 0.08mm. The 2JZ has a tolerance of 0.0024"
Have you measured the runout?
What tolerance did you use for the bearing clearances?
If I were you I'd have both cranks checked before continuing with the build. Also the carrier bearing saddles should be checked, just to be sure.
