Abstract
A crankshaft bearing inspection system for confirming the presence of bearing inserts and the proper amount of bearing crush during assembly of reciprocating machines accomplished by measuring a fastener tension related function and a function fastener rotation, and evaluating the curves thus obtained to confirm and identify a characteristic signature of the bearing presence as, for example, a first constant rate of tension increase followed by a second increased constant rate of tension increase falling within expected inspection limits.
