Anyhow manage to get the upper oil pan off. To me, it’s worst than removing the cylinder head.
Just remove cylinder 1 rod bearing to check the size. Which was std. I was surprised to see the lower bearing has more wear than the upper. The crank was in great shape.
Going to go with oem bearings as the other were all race tri-metal bearings which I don’t intend on rebuilding anytime soon.
Bottom is lower bearing.

Ok so flats on the shaft lock into position. Is the shaft worn or the hub or both? Very disappointing this happened on a new pump. I wonder if this is the same pump stock that was causing all the failures in th M5's S63.
