Abstract
A special purpose tool for manual installation and removal of bushings or sleeve bearings from press fit bearing housings within automotive engines, transmissions, and other machinery with no resultant damage to the housing is disclosed. The present tool is comprised of a cylindrical body member including a pilot diameter, which aligns the tool in coaxial relation to the bushing and a bushing locating journal that engages the bushing to be removed. A plurality of machine screws are disposed in the body member at predetermined radial positions. To remove a bushing the machine screws are advanced axially within threaded holes such that the machine screw threads tap into and capture the worn bushing and/or bearing sleeve and the tool is withdrawn. The present tool is also utilized to manually install new bushings into housings and other components by removal of the aforementioned machine screws.
