Abstract
A swashplate style pump uses a dual location cluster bearing of consistent configuration for use in each of two positions in the pump. In one location the dual location cluster bearing will interface with pistons and the swashplate cam. In a second location the dual position cluster bearing will interface with the non-camming side of the swashplate and the back plate of the pump. The dual position cluster bearing can be used in either and both positions with equal facility.
