DETAILED DESCRIPTION OF FIGURES

[0016] In this description, the directional prepositions of up, upwardly, down, downwardly, front, back, top, upper, bottom, lower, left, right and other such terms refer to the device as it is oriented and appears in the drawings and are used for convenience only; they are not intended to be limiting or to imply that the device has to be used or positioned in any particular orientation. Conventional components of the invention are elements that are well-known in the prior art and will not be discussed in detail for this disclosure.

[0017] FIG. 1 shows an exploded perspective view of a preferred embodiment of the device comprised of cylindrical cap body 2 and interchangeable drive hub 3 being operated on a conventional oil filter 1 (not part of the disclosure) using conventional ratchet 4 (also not part of the disclosure). FIG. 2 showing one side of cylindrical cap body 2 having circular aperture 11 with retaining ring protection lip 10 configured proximally. An edge of cylindrical cap body 2 having a raised portion with fluted formations to grip a standard oil filter herein referred to as filter flutes 8.

[0018] FIG. 3 showing another side said cylindrical cap body 2 having a circular shaped depression 6 with a square-shaped drive aperture 7 disposed proximally to engage interchangeable drive hub 3. Interchangeable drive hub 3 has a mating square connection 15 also having a cylindrical protrusion 16 with a grooved recess 17 to receive retaining ring 12 therein. Said interchangeable drive hub 3 also having a proximal positioning flange 13 that positions it on cylindrical cap body 2. Another end of interchangeable drive hub 3 having two embodiments of different sized, square-shaped apertures (herein referred to as ratchet drive hole 5) configured to receive either a ⅜-inch or ½-inch ratchet drive as well as detents on the inner walls to engage a spring-loaded ball detent on a ratchet drive. The drive hub 3 and cap body 2 are made of a rigid material including but not limited to: aluminum, steel, titanium and the like and being manufactured by means of a plurality of processes including but not limited to: casting, 3D sinter printing, die stamp forging, machining, and the like.

[0019] FIG. 4 showing a representative view of the device's method comprised of but not limited to the following steps: selecting either a ⅜-inch or ½-inch ratchet; the user inserting the proper sized interchangeable drive hub embodiment into the cylindrical cap body; locking the cylindrical cap body to the interchangeable drive hub with retaining ring, inserting the cylindrical cap body onto an oil filter; installing the ratchet into the interchangeable drive hub; turning the ratchet and removing said filter from cylindrical cap body.
