Interchangeable Lubricating Oil Pump For Use With Two Engines Having Different Lubrication Requirements And Method of Manufacturing Same

摘要

An interchangeable lubricating oil pump for use with two internal combustion engines having different lubrication requirements includes a pump housing and a drive shaft rotatably supported in an opening through the pump housing. A first end of the drive shaft provides a drive gear mounting location. First and second idler gear mounting locations of the pump housing are positioned a common distance from the drive gear mounting location. The interchangeable lubricating oil pump also includes a set of interchangeable gears including a small interchangeable gear and a large interchangeable gear. A first configuration for a first internal combustion engine having a first lubrication requirement includes the large interchangeable gear mounted at the drive gear mounting location and the small interchangeable gear mounted at the first idler gear mounting location. A second configuration for a second internal combustion engine having a second lubrication requirement includes the small interchangeable gear mounted at the drive gear mounting location and the large interchangeable gear mounted at the second idler gear mounting location.
