This is the center main bearing journal of a CAT 3516 engine crankshaft and as you can see there are these colour stripes but by inspection with hand i can't feel any bitting or roughness.
This journal doesn't have oil hole
Anybody have seen this before?
What is the cause of it?
Is it normal, abnormal or critical condition?
