ABSTRACT:
A tool is disclosed for replacing the washer in a planetary gear of the type having a frame, an elongated axle having both ends secured to the frame, a gear rotatably mounted to the axle and in which the washer is disposed around the axle between one end of the gear and the frame. The tool includes a plate having a top surface and a bottom surface. At least one arcuate cut-out is formed in the plate which receives a portion of the frame containing the gear. With the planetary gear positioned within the cut-out, the axle registers with at least one recess formed in the top surface of the plate. Thereafter, an elongated punch drives the axle into the recess thereby exposing the washer and enabling its replacement. Thereafter, the axle is again driven through the replacement washer and the end of the axle is staked to the planetary gear frame thereby completing the repair. Preferably, a raised nub is provided on the top surface of the plate which registers with a lower end of the axle during the staking operation.
