Abstract
Gear pumps use various types of bushings or bearings (sleeves) between a shaft and the housing of the pump. From time to time, these sleeves wear out and have to be replaced. This extractor removes the sleeves and includes three main components—a collet or sleeve engaging member, a mounting bracket, and a lift screw. The extractor may also include other components within the scope of the invention, including melting screws and washers.
