Hand tool having multiple end pieces for assembling disassembling

Abstract

A hand tool for assembling and disassembling constant velocity joints of varing size is disclosed. The hand tool includes a handle portion connected to one end of a generally C-shpaed body portion. The other end of the C-shaped body portion includes a projection extending outwardly in general longitudinal alignment with the handle portion. The projection is adapted to receive one of a plurality of differently sized end pieces thereon. Each of the end pieces is formed generally in the shape of a hollow cylinder having one closed end. The inner diameters of all of the end pieces are equal to each other, and all are slightly larger than the outer diameter of the projection. The outer diameters of the end pieces are all different, corresponding to a constant velocity joint having a different size. An O-ring is provided for selectively retaining one of the end pieces on the projection for use with a given size of constant velocity joint. Additonally, an enlarged hook portion is formed on the C-shaped body portion. In one embodiment of the invention, the hook portion is formed integrally with the C-shpaed body portion. In another embodiment, the hook portion is formed by a hook pin which is slidably disposed in a recess formed in the C-shaped body portion. A pin is provided for selectively retaining the hook pin in one of a plurality of extended positions so that the extended length thereof may be varied in accordance with the size of the particular constant velocity joint. The hand tool is adapted to be inserted within a constant velocity joint to move the joint to a position where it can be disassembled and re-assembled.
