Very user-friendly tool to extract the starter bearing from the outer primary cover. Bearing can easily be removed, even if the cover has been chromed with bearing installed. Works on all Big Twins 1965 thru 1988 that use needle bearing OEM 9063 for the starter shaft. This tool will also remove the countershaft gear bearing (OEM 35961-52) used on Big Twins 1952 thru 1990 as well as 4 speed Sportster clutch gear.
