Pinion disassembly tool and method

摘要

A pinion disassembly tool is configured to remove a yoke or a flange member and a pinion fastener from a splined pinion shaft in a pinion assembly. The tool includes a yoke holding plate with a central aperture sized to receive a socket wrench during removal of the pinion fastener. The yoke holding plate includes fastener apertures for connection to the yoke and at least one non-circular aperture for receiving a breaker bar during removal of the pinion fastener. The tool also includes a drive plate with a threaded aperture, the drive plate inserted through the central aperture of the yoke holding plate after removal of the pinion fastener. The tool also includes a drive bolt engaged with the threaded aperture and configured to force the drive plate and the yoke holding plate to pull the yoke from the splined pinion shaft as the drive bolt is rotated.

1. A pinion disassembly tool configured to remove a yoke or a flange member from a splined pinion shaft in a pinion assembly, the tool comprising:
a yoke holding plate including a central aperture defining a non-circular inner periphery and sized to receive a socket wrench during removal of a pinion fastener from the pinion shaft, a plurality of fastener apertures positioned around the central aperture and configured to receive fasteners coupled to the yoke or the flange member, and at least one non-circular aperture configured to receive a breaker bar during removal of the pinion fastener; a drive plate defining a non-circular outer periphery and configured to be inserted completely through the central aperture of the yoke holding plate after the removal of the pinion fastener, so as to engage the yoke holding plate after being inserted completely through the central aperture, the drive plate including a threaded aperture; and a drive bolt engaged with the threaded aperture of the drive plate, the drive bolt forcing the drive plate into abutting contact with the yoke holding plate to pull the yoke or the flange member from the splined pinion shaft as the drive bolt is rotated into engagement with the pinion shaft.
