Abstract
A method of detecting premature wear of engine bearings in locomotive engine applications includes incorporating bismuth as a tracer element into the liner of bearing metal applied to a rigid metal backing of the bearing. A soft metal overlay free of bismuth is applied over the bearing liner and the bearing installed in the engine. The engine oil is periodically tested for the presence of bismuth. Early detection indicates premature wear of the overlay, enabling corrective action to be taken to protect the engine.
