A system for an internal combustion engine is provided. The system includes an oil pan, a pick up tube; and a spacer. The spacer is positioned vertically above a static oil level and secured to a surface of the oil pan. Further, the spacer may include an opening that may communicate with oil when the oil is in a tilt orientation.

A method of verifying spindle bearing functionality prior to service, comprising: assembling a machine-tool spindle having an outer housing rotatably supporting an inner spindle shaft about a spindle axis by use of roller bearing sets, at least one set being compressed along the spindle axis to promote a resilient bearing preload force between the housing and shaft; suspending the housing of said assembly on a non-resonating flexible support, the spindle shaft being essentially isolated from the housing except for the preloaded rolling bearing set; sharply striking the inner spindle shaft along said spindle axis to induce an axially oscillating frequency; measuring the oscillating frequency in the shaft as it is affected by the degree of bearing preload of such at least one bearing set; and comparing the measured induced frequency to a known frequency analysis for the type of spindle assembly which is correlated to varying bearing preloads, the comparison indicating the spindle bearing functionality prior to service.

A spindle characterization system for characterizing performance of a spindle used in an industrial machine includes a machine base for providing a mounting and support surface and having a recessed portion. The spindle characterization facility includes a table base assembly for supporting the spindle disposed within the recess portion and the table base assembly has a table top and height adjustment mechanism for adjusting the height of the table top. The spindle characterization system also includes a spindle mounting mechanism having a top portion mounted to the spindle and a bottom portion mounted to the table top, and a spindle forcing assembly operatively connected to the spindle, and the spindle forcing assembly generates an axial load, radial load and a torque that is applied to the spindle to simulate a machine tool load. The spindle characterization facility further includes a programmable controller operatively connected to the spindle forcing assembly for providing computerized numeric control, and a computer system in communication with the programmable controller.
