Oil Pump Gear Clearance at Alexander Jarrett blog

Oil Pump Gear Clearance. Ideally, a new oil pump should have tolerances that are on the tight end of the range (.003˝ between the gears and housing, and.002 to. there has to be a little bit of clearance to compensate for thermal expansion when the pump and oil get hot, but not so much clearance that it allows excessive leakage between the gears and housing. Pulling the cover off the pump and sanding or grinding it flat can help tighten up the end clearance between the gears and cover, but it won’t do anything to. Make sure that the face of the pump is clean, and put a straightedge across it. check the clearance between each gear tooth and the pump body. Periodically check for wearing of the teeth by attempting to pass a piece of paper between the clearances. maximum clearance between the gears or pump cover should not exceed.005 to.006˝ because it will reduce pump efficiency, oil flow and pressure. thermal expansion of the casing and gears reduces clearances within a pump and this can also lead to increased wear, and in extreme cases, pump. At the closest point it should typically be no more than.006in. wear between the gears, the gears and the housing, and the gears and the pump cover provide leak paths that can hinder a pump’s ability to generate normal flow and pressure. High mileage used pumps can have even greater clearances. A new gear pump has.007 to.005 inches of clearance from both the teeth and chamber of the gears.
