Patent number: 4507838Abstract: A tool for removing and replacing automobile wheelbearings without removing either the axle or the bearing housing and without applying pressure to the axle. A frame is provided which is adapted to be secured to the bearing housing. An extractor is movably connected to the frame to travel between an advanced and retracted position. When the frame is secured to the bearing housing, the advanced position of the extractor places it in the bearing housing between the axle and the central opening of the bearing, with the end of the extractor being past the bearing. The end of the extractor is operable between an expanded and retracted state. In its expanded state, the end of the extractor cannot be moved through the central opening of the bearing and thus moving the extractor to its retracted position while it is expanded will draw the bearing out of the housing.Type: GrantFiled: April 9, 1982Date of Patent: April 2, 1985Inventor: Karl M. Hacker

Patent number: 4330917Abstract: A hand-held tool to use in extracting ring seats from housings such as small engine carburetor needle inlet valves is disclosed. The tool has a generally cylindrical handle means. From one end of the handle means a helical or threaded arm projects, ending in a tip. By inserting the extracting arm into the housing, pressing the arm end opposite the seal and turning the tool, the seal threads itself on and up the arm. Withdrawing the tool with the threaded seal on it from the housing thus removes the seal. A further embodiment combines with the foregoing a tamping member which projects from the other end of the handle means. The tamper, with its tip, aids in inserting a fresh seal in the housing.Type: GrantFiled: March 20, 1980Date of Patent: May 25, 1982Inventor: Damon Dzurkovich
