Abstract
A tool for installing a retrofit bearing having a length that extends beyond the original location of a tapered sleeve used to secure an original bearing and a method of performing the installation provide a reliable way to replace an engine bearing that supports and extends within a shaft end. The tool includes a flange with holes matching the engine block, a body coupled to the flange for accepting the captive portion of the replacement bearing, and a tapered sleeve disposed within the tool body for compressing a wire lock engaged with a mating channel of the replacement bearing when the captive portion is in the tool. The tapered sleeve has a diameter that mates with an inside diameter of an end of the engine shaft, so that the wire lock remains compressed until it engages with the channel provided in the engine shaft for the original snap ring.
