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.

Abstract: A rocking journal bearing is provided in a piston coupling mechanism. The bearing includes a sleeve and a wristpin constructed with two sets of eccentrically-disposed bearing surfaces which alternate in accepting a compressive load during an operational cycle of the bearing. The sleeve includes a network of grooves to transport oil to the bearing surfaces. Lubricating oil flow through the bearing is minimized by limiting provision of pressurized oil from the wristpin to the network of grooves to portions of the cycle when one or the other of the sets of bearing surfaces receives the compressive load.
