Abstract: An engine system includes an internal combustion engine, a driven unit, and a torsional coupling between a crankshaft of the engine and a driveshaft of the driven unit. The torsional coupling includes a driven-side disc coupled to the driveshaft, and a flywheel having an engine-side disc coupled to the crankshaft. The engine-side disc has an axial thickness in a discontinuous thickness range from about 0.2 inches to about 0.3 inches, so as to flex the engine-side disc predominantly over the driven-side disc in response to the driveline deflecting loads.

Abstract: A rocker arm assembly for a valve operation in an engine includes a rocker main body extending between a first end and a second end. The first end of the rocker arm main body is configured to receive a valve actuation button and the second end of the rocker arm main body is configured to receive a cam roller assembly. The cam roller assembly includes a cam roller and a bushing is disposed in the cam roller forming a bearing surface. Further, the cam roller assembly includes a bearing component which is disposed in the bushing forming a bearing surface. The bearing component includes an oil hole with an oil delivery pocket which is curved to form a rounded edge and an transitional opening is formed extending from the rounded edge.
