A lubrication distribution assembly is provided. The lubrication distribution assembly includes a lubrication metering device, which includes a piston. The lubrication distribution assembly also includes a sensor and a controller. The sensor automatically detects a piston stroke length of the piston over at least two movement cycles of the piston. The controller receives the piston stroke length from the sensor, sets an operating point of the piston based on the piston stroke length, and controls the lubrication metering device by utilizing the set operating point.

A flow restrictor assembly includes a threaded element and a sleeve. The threaded element defines a plurality of threads that extend from a first threaded element end towards a second threaded element end. The sleeve has an inner sleeve surface that engages edges of a portion of the plurality of threads and extends between a first sleeve end and a second sleeve end. A lubrication flow path is defined by the portion of the plurality of threads and the inner sleeve surface and is arranged to create a pressure drop in a lubricant that flows through the lubrication flow path.

The lubricant filter system can have a first lubricant filter having a first inlet and a first outlet; a second lubricant filter having a second inlet and a second outlet; an inlet conduit; a first inlet branch fluidly connecting the inlet conduit to the first inlet; a second inlet branch fluidly connecting the inlet conduit to the second inlet; an outlet conduit; a first outlet branch fluidly connecting the first outlet to the outlet conduit; a second outlet branch fluidly connecting the second outlet to the outlet conduit; a bypass conduit fluidly connecting the inlet conduit to the outlet conduit; and a bypass valve controlling fluid passage through the bypass conduit.
