A spin-on filter cartridge ( 20 ) comprising a cannister ( 21 ), a filter element ( 22 ), and an adaptor-mounting plate ( 24 ) positioned within the cannister ( 21 ) between its open end and the filter element ( 22 ). The adaptor-mounting plate ( 24 ) has a scooped-ramped inner perimeter that allows non-threaded engagement with an adaptor ( 60 ). To install the filter cartridge ( 20 ) onto a threaded mounting stud ( 61 ), the cartridge ( 20 ) is rotated (e.g., "spun") relative to the stud ( 61 ). |
