  • Publication number: 20180065238
    Abstract: An apparatus for removing an upper bearing housing from an outboard motor. According to an embodiment, an upper bearing housing apparatus is generally comprised of a hollow body, a slide hammer, a claw collar, two or more claws, and a hammer stop. The apparatus is utilized to remove an upper bearing housing by threading the drive shaft through the hollow body of the apparatus and positioning the claws on opposite sides of the upper bearing housing. A tooth portion at the end of each claw is used to grip an underside of the upper bearing housing. The user applies force to remove the upper bearing housing by sliding the hammer portion upward and striking it against the hammer stop. This generates force on the claw teeth to the pull the upper bearing housing free from the gear case, without damaging the gear case housing and the bearing housing.
