anyone know the standard journal sizes for the crank in the pilots as fitted to d46u crawlers so i can work out how worn my crank is and if its worth fixing.

i havent been able to find this info.

You should have it magnafluxed before you grind it. The guys that did my cranks said that when they were grinding a lot of these for the Cat dealer they had almost 50% fall out with cracks. I just got 6 cranks ground and none had cracks. None of them had broken rods when I took them apart though.
