Abstract
A method for filtering a fluid that includes collecting contaminates in the fluid, passing the fluid from inside an internal cavity of a first shaft through a tight clearance at a spline connection between the first shaft and a second shaft such that the fluid is filtered of contaminates as a result of the tight clearance, and delivering the filtered fluid to a delivery location.
