Abstract
A biasing member assembled with a bearing and a crankshaft wherein the bearing is configured to receive the crankshaft. The crankshaft is assembled with an internal combustion engine. The biasing member biases the bearing in an axial direction relative to the crankshaft to reduce an endplay of the crankshaft while the engine is operable in a normal operating condition. The biasing member provides a resilient biasing force for biasing the bearing into engagement with a cylinder block when the crankshaft is operational to thereby eliminate or reduce the crankshaft endplay and improve the sealing performance of a crankshaft axial seal.
