I need some help figuring out which bearings I need. I know how to match the letters on the block and the numbers on the crank, but I cant read some of the numbers. Is there another way to tell, or can I somehow make the numbers more visible by lightly sanding or cleaning with some sort of solvent. I dont want to mess up the crank by sanding, or using something that would somehow affect the coating on the journals. I have the bearings that were originally there and they are color coded, but I think this engine has been rebuilt at some point because one of the rod bearing caps was facing the opposite direction from the other three, so I dont want to trust that they are the right sizes. Any help or recommendations would be greatly appreciated. Here is a picture of the crank, it may help you understand what I am talking about. The fourth nob over has a 1 and the sixth has a 2, but that is all I can make out. And the crank is not being stored on it side like in the picture, it is standing on its end.
