Abstract : This patent discusses a jet engine compressor stage puller that engages the lip of each disk and spacer section of a jet engine compressor, and the end of the compressor shaft. A guide bar has a central threaded hole through which a bolt is threaded. A cup integral with the bolt engages the end of the compressor shaft. A pair of guide rods pass through slots in the guide bar, the slots being symmetrical about the central threaded hole. Shoes attached to the ends of the guide rods engage the lip of each disk or spacer section to be removed. As the bolt is rotated a force is exerted to pull the shoes upward, and thus loosen the disk and spacer stages without danger of damage to compressor parts or hazard to personnel.
