Thrust bearing wear
I think about every time I have disassembled one of my engines, the thrust bearing surfaces looked more or less like this, even though the main bearing surfaces looked acceptable, as these do..
Has anyone had an engine failure because the thrust bearings wore too much, even though the regular parts of the bearings were fine?
For a street motor, especially with the 930 pump, I'd not think center main crank oiling for the rods (crossdrilling) would be all that important. How high in the RPM range do you think you will twist it?
