ABSTRACT:
A tool for removing an oil filter cartridge cap threadably attached to an engine has pins for engaging oil passage holes in the cartridge cap after the filter cartridge housing is partly removed to remove the filter cartridge, thereby exposing the cartridge cap. The tool includes a drive disk adapted to be engaged by a wrench and an interchangeable base disk to be engaged by the drive disk and having the aforesaid pins for engaging the oil passage holes. Plural base disks are provided to match filters having different hole patterns. A central hole in each disk provides clearance for the threaded nipple by which the oil filter cartridge cap is threadably attached to the engine.
