Abstract
A full, one-piece, wrap around bumper for a crankshaft pendulum is disclosed. The pendulum includes two halves. Continuous, mirror-image bumper-receiving channels are formed in each pendulum half. When the two halves are attached, the bumper is captured between therebetween and is retained by a crush fit. Each pendulum half includes an elevated central area and a pair of recessed areas with each recessed area formed on one side of the elevated area. Side walls are formed at the intersections of the elevated area and the recessed areas. A base wall is formed along the lower edge of the elevated area. The continuous channel in each half is formed along portions of the side walls and along the entire length of the base wall. The elongated, one-piece bumper wraps around the side walls and the base wall and extends from the elevated area beyond the side and base walls.
