High performance oil pump

摘要

An oil pump for high performance internal combustion engines suitable for use with race cars and the like wherein extended wear and tolerance maintenance is achieved by supporting the pump gears on shafts extending through the gears. Balanced dual support of the pump gears is achieved by forming bearing openings in the pump lower housing receiving the lower gear shaft portions and lubrication of the lower housing supported gear shafts is achieved by oil passages communicating with the bearings and the lower housing oil outlet cavity. Screw in plugs and retainers are employed to insure effective assembly even under high vibration, and a bolt-on screened oil inlet achieves superior rigidity and ease of replacement.
