Abstract
A pawl disengagement tool intended for use with a slack adjuster has an elongated handle with a first end and an opposite second end, and a longitudinal axis extending from the first end to the second end. A slotted aperture formed at the first end includes a hole with a diameter that is greater than the first diameter of the pawl cap. A first slot extends from the hole and has a width that is greater than the second diameter of the pawl shaft of the pawl assembly of the slack adjuster. A portion of the tool defining the hole includes a chamfered periphery. The chamfered periphery defines an inclined plane leading to the first slot. The inclined plane has a thickness that increases up to a thickness equal to a disengagement thickness. The disengagement thickness is effective to cause disengagement of the pawl assembly. The second end of the tool includes a forked end that includes a pair of parallel spaced apart wedge-shaped prongs. In use, the forked end or slotted aperture is manipulated (e.g., slid) to a position between the pawl cap and the body of the slack adjuster. Then the slot of the pawl disengagement means is advanced between the pawl cap and the body of the slack adjust…
