A jack device employed to extract agitators from the drive shafts of washing machines. The device includes an annular split ring member having two closed ends and enclosed chamber therein. The enclosed bladder device expands into a split toroidal configuration. A tube attached at the periphery and extending from under the agitator to the outside tub is employed to transfer hydraulic or pneumatic pressure into the said device resulting in expansion of the same. The wall of the bladder is thicker in a zone around the periphery than elsewhere. This thicker zone prevents the device from ballooning out from under the agitator which would result in failure of successfully removing the agitator from the shaft. |
