IMPROVEMENTS IN VEHICLE SLACK ADJUSTERS ABSTRACT OF THE DISCLOSURE A slack adjuster for use in a transportation environment has a body which has a lever arm formed at one end thereof. There is an opening in the body and a worm gear wheel is positioned in the opening for mounting on a brake operating shaft. There is a slot formed in the body and contiguous with the opening. The slot has three mutually perpendicular surfaces and is of a size and shape to hold a worm gear and to provide for threaded engagement of the worm gear and the worm gear wheel. There is a bore in the body which is generally perpendicular to one of the slot mutually perpendicular surfaces. A shaft is positioned in the bore and coaxially mounts the worm gear for adjustment thereof. The bore is oversized relative to the shaft, thereby providing no bearing support therefore A torque applied to the worm gear wheel from the body lever arm applies a resultant force, parallel with the worm gear axis, from the worm gear to one of the slot perpendicular surfaces. -1-
