Abstract
A counterbalancer for an engine, the counterbalancer having a housing, a first shaft and a second shaft each positioned within the housing such that the first shaft is configured to be rotated by the engine in use. A first gear and a first weight are each non-rotatably coupled to the first shaft and a second gear and a second weight are each non-rotatably coupled to the second shaft. The first gear and the second gear are meshed such that the first weight and the second weight rotate together to counterbalance the engine in use. The counterbalancer further includes roller bearings that rotatably support the first shaft and the second shaft within the housing and retainer clips that prevent axial movement of the bearings within the housing.
