Abstract: An engine assembly may include an engine structure supporting a camshaft and a valve lift mechanism. The camshaft may include a cam lobe and may define a longitudinally extending rotational axis. The valve lift mechanism may define a longitudinally extending cam engagement surface and a first side wall. The cam engagement surface may be engaged with the cam lobe at a first location. The first side wall may be fixed to the cam engagement surface and may include first and second portions. The first portion may extend from the cam engagement surface. The second portion may extend continuously inward from an end of the first portion. The inward extent of the second portion may be greater than or equal to a first height at the first location defined from the cam engagement surface to the end of the first portion.

Abstract: A camshaft assembly may include a first shaft adapted to be rotationally driven, a first lobe member fixed for rotation with the first shaft, and a torsional damper fixed to the first shaft. The torsional damper may include a mass structure fixed to the first shaft and an elastic member disposed between and coupling the mass structure and the first shaft. The elastic member may have a spring constant providing a first sideband natural frequency and a second sideband natural frequency for the camshaft assembly.

Abstract: An engine assembly includes an engine structure, a camshaft supported on the engine structure, a first cam phaser coupled to a first axial end of the camshaft, and a locating pin. The camshaft includes a first shaft, a second shaft, a first cam lobe and a second cam lobe. The first shaft defines a first opening. The second shaft is supported within the first shaft and defines a second opening. The first cam lobe is located on and fixed for rotation with the first shaft. The second cam lobe may be located on the first shaft and fixed for rotation with the second shaft. During assembly, the first cam phaser is located on the camshaft and the locating pin may be inserted through the first and second openings to rotationally fix the first and second shafts. The first cam phaser is then secured to the camshaft.

Abstract: A stake punch for securing a pin in a gearset is provided. The stake punch includes a body defining an axis and a punch extending from the body along the axis. The punch includes a pair of opposing top and bottom surfaces, an end face, and a pair of stake faces each connected to the end face. The stake faces each have a curved surface extending between the top surface and bottom surface. The curved surface has a constant radius of curvature along a length of the stake face. The pair of stake faces are at an angle with respect to the axis.
