Abstract: An oil drain plug and wireless oil level sensor assembly is provided including an oil drain plug having a shaft and a head, the shaft having external threads and an axial passage extending axially therein in communication with at least one radial passage extending through the shaft from the axial passage to an exterior of the shaft. An oil level sensor includes a housing having an annular mounting portion defining an aperture extending there through for receiving the shaft of the oil drain plug. A pressure transducer is in fluid communication with the aperture and connected to a circuit and a battery disposed within the housing that provide wireless signals representative of the oil level.

Abstract: A tensioner device for a belt or chain defines a housing defining a bore with a plunger disposed in the bore. A spring is engaged with the plunger for biasing the plunger in an outward direction. The housing further includes an oil chamber connected to an oil passage in communication with the oil chamber for delivering pressurized oil to the oil chamber, wherein when the oil chamber is pressurized the pressurized oil applies a counter force opposing a force of the spring.

Abstract: Embodiments of the disclosure include a centrifugal pump assembly including a pump housing defining a cavity and an impeller disposed within the cavity, the impeller being affixed to a shaft. The pump housing includes an inner surface having a geometric pattern configured in increase a turbulence of a fluid flow over the inner surface. The impeller includes one or more blades and a shroud. The inner surface of the pump housing and the shroud of the impeller define a leakage path.
