Abstract: A method of improving an internal surface topography of a manufactured workpiece includes filling a workpiece with an electrically conductive magnetorheological (MR) fluid. The workpiece includes at least one internal feature having an inner surface with at least one irregularity. The method further includes converting the MR fluid into a rigid MR material, applying a voltage to the rigid MR material, and ablating the inner surface in response to the voltage to remove the at least one irregularity.

Abstract: A standpipe assembly configured to connect to a starter that includes a housing is described herein. The standpipe assembly includes: a standpipe having first and second openings at opposite ends of a hollow passageway, wherein the standpipe, upon being connected to the starter, is oriented within the housing so that the standpipe drains oil through the standpipe when oil in the housing reaches an overfill level, and is oriented in parallel to internal oil flow in the starter to inhibit interference with the internal oil flow during operation of the starter; and an attachment portion, wherein the attachment portion is structured to attach the standpipe assembly to the housing of the starter and prevent movement of the standpipe assembly with respect to the housing of the starter.
