ABSTRACT:
A bearing puller for removing from a shaft a bearing having a tapered eccentric flange on its inner race includes a cylindrical tube disposed within an outer cylindrical housing. The puller tube is capable of sliding displacement within and along a portion of the length of the outer housing and includes a first end having outer threads for engaging and maintaining a puller nut on a first end of the housing. The puller nut includes a threaded aperture on an end thereof for receiving a draw bolt which is inserted in the housing and extends to a second opposed end thereof. A second end of the sliding puller tube includes a peripheral flange for engaging first and second paired split jaw members each having a respective inner tapered flange on a distal end thereof for engaging the tapered flange on the bearing's inner race. With the two split jaws engaging the bearing's inner race, the outer housing is slid over the puller tube so as to cover the split jaws which are thereby maintained in secure engagement with the inner race's tapered flange. An end of the draw bolt is placed in contact with an end of the shaft and is tightened, moving the outer housing, puller tube and pair of split jaws along the longitudinal axis of and away from the shaft and removing the bearing from the shaft.
