Ok, finally back on the pig.
Cleaned all the engine internals and block up with mineral spirits. Then they got a hot soapy bath followed by a good dose of brake cleaner. That right there is the crank getting all nice and cleaned up.
I had my new bearings coated by PolyDyn. Never had that done before. Figured it couldn't hurt. Here is the new main bearings, fresh in their packaging back from being coated.
First thing was to put the main bearings in. They only go in one way and the thrust bearing goes on the 4th main, facing upwards, or into the block. The cap just gets a standard cap bearing on that main journal. I used plastigage to check the clearances on the rod and mains. It is a wax based product designed to get squeezed and measured to determine bearing clearances. It is a good way to verify that everything is within spec during the final build. Here you can see this main has .002" of clearance.
