I Just began checking bearing clearances. I noticed something odd on the lower shell of the main bearings. The 107M bearings are 3/4 grooved. Next the grooves on one side of the bearing is an indentation (or cut into) the face of the main bearings. Sort of looks like a chewed up bearing tang on the face of the bearing. This is only on the lower shell, on one side and this indentation is not on the thrust main bearing. The upper shell has the oil groove on the face only, but no matching indentation for the face of the lower shell. Does anyone know what that indentation is for. Federal Mogul is under the impression that I have encountered a mis-boxed item (even though Merkel claims 3/4 grooved main bearings would soon be available). The bearings spec okay, I'm just concerned about the indentation on the lower bearing face.
