Abstract:
1. A device for installing a spin on oil filter on an engine in a general location relative to the engine casing previously occupied by an internal cartridge oil filter wherein the engine casing has a threaded opening for the passage of oil comprising: a mount filter adaptor; a housing filter adaptor; said mount filter adapter having external threads along its longitudinal axis; said mount filter adaptor having a flange located between its ends and extending radially outward perpendicular to the longitudinal axis of said adaptor to define a surface with greater diameter than the threaded portion of said mount filter adaptor for limiting travel when said adaptor's threads are engaged in a mating relationship with an engine casing having a threaded oil passage opening; said mount filter adaptor flange having at least one flat edge on its outer surface with flange dimensions permitting secure mating with a standard socket wrench for ease of installation; said mount filter adaptor having a hollow interior and openings at either end for allowing the passage of oil there through; said housing filter adaptor having a substantially cylindrical opening with dimensions at one end permitting the insertion of a standard spin on oil filter within said opening; said housing filter adaptor having a flange at the open end of its cylindrical opening and extending around the periphery of said opening to form a sealing surface with which to engage the engine easing surface; said housing filter adaptor having a threaded hole centered in the bottom of the other end of said cylindrical opening for threaded engagement with the threads on the exterior of said mount filter adaptor; said housing filter adaptor having at least one hole in said other end of said cylindrical opening and spaced radially outward from said threaded hole to permit the passage of unfiltered oil into the intake ports of a spin on oil filter; said housing filter adaptor, said mount filter adaptor and a spin on oil filter forming when screwed together an oil tight assembly which permits unfiltered oil to enter the filter and filtered oil to re-enter the engine, said housing filter adapter flange having at least two slots located directly opposite from each other on the flange circumference for receiving an installation tool which can be used to impart a torque force to said adaptor for installing or removing it.
