Abstract
A tool for pulling off the clutch mechanism of one specific make of washing machine. The tool has main mounting plate from each end off which passes therethrough an elongated screw. The mounting plate has an enlarged central hole for passing therethrough a large tubular member which is threaded on its outer circumferential surface, and which is hollow in it interior. The tubular member receives in its hollow interior the tubular sleeve of the clutch mechanism when the tool of the invention is used for pulling the clutch mechanism off from the drive shaft. At the bottom of tubular member, there is provided a larger-diameter head, having a pivotal latch. After placing the tubular member over the tubular sleeve, the pivotal latch is closed over cutout portion at the lower portion of the tubular sleeve, whereby the latch is thus in locked engagement with the tubular sleeve but free of contact with the inner drive shaft. The tool is then used by rotating a nut mounted on the upper end of the tubular member and above the mounting plate. Since the bottom heads of the two screws at the ends of the mounting plate are in contact against the motor housing, rotation of the nut causes the tubul…
