ABSTRACT:
A tool for removing sleeves from cylinders having an unrestricted opening at one end and a restricted opening at the other end. A stabilizer or guide rod device having a disc with a diameter closely approaching the internal diameter of the sleeve is placed adjacent a shoulder of the sleeve with a further disc used as a stabilizer within the sleeve. From the restricted opening of the cylinder housing having an internal diameter less than the diameter of the sleeve a plurality of radial or pie-shaped collar segments are inserted and placed on top of the stabilizer support disc and fitting over the shoulder of the sleeve. A pusher rod is inserted through the restricted opening of the cylinder and connected to the stabilizer support disc with apparatus for clamping the collar segments thereto. The pusher rod with the clamped collar segments extending over the shoulder of the sleeve in clamped relation is moved or pushed to force the sleeve out of frictional engagement with the cylinder and is removed therefrom.
