Abstract
A lubricant filter assembly includes a filter cartridge including a cylindrical filter medium and a top cap. The cylindrical filter medium extends circumferentially about a longitudinal axis of the filter assembly. The cylindrical filter medium extends between and to a first filter end and a second filter end along the longitudinal axis. The cylindrical filter medium forms a filter passage extending from the first filter end to the second filter end. The top cap is disposed on the cylindrical filter medium at the first filter end. The top cap includes an inner diameter ring, an outer diameter ring, and an interior packing. The inner diameter ring forms a first filter outlet passage coincident with the filter passage. The inner diameter ring includes a first set of locking tabs. The outer diameter ring radially circumscribes the cylindrical filter medium.
