US 8,281,474 B2 · Tool and method of use for extraction of failed wheel bearings

Abstract

A tool and method of use directed to the extraction of a wheel bearing's outer ring. When a tractor or trailer's wheel bearing fails and is in need of replacement, the present invention provides for a quick and easy means of extracting the remaining wheel bearing component residing in the wheel rim, the outer ring. The tractor wheel bearing extraction tool of the present invention is comprised of two pieces. The first piece is inserted into the wheel cylinder within the wheel rim and locks to the wheel bearing outer ring. The tool's first piece thus provides for a punching back for the second piece of the tractor wheel bearing extraction tool. The second piece is a hammering rod and is inserted into the opposite end of the wheel cylinder within the wheel rim. The hammering rod locks into the first piece and allows the user to hammer out the outer ring wheel bearing component with one strike.
