ABSTRACT:
A puller for a brake slack adjuster having a housing mounted on a mounting shaft and an elongate arm comprising a central portion having a threaded opening alignable with the mounting shaft, a first grasping arm extending from the central portion adapted to straddle and engage the adjuster housing and a second arm extending from the central portion adapted to overlie the adjuster elongate arm. A connecting bolt extendable between the second arm and the adjuster elongate arm is provided to allow for joining of the two arms. A threaded shaft is located in the threaded opening and engages the end of the mounting shaft whereby turning the threaded shaft acts to move the puller relative to the mounting shaft such that the adjuster is pulled from the mounting shaft. In a second embodiment, the central portion is formed with a cup-shaped flange adapted to surround a portion of the member to be removed from the shaft.
