Abstract
Tool for installing and removing anti-friction skate wheel bearings press fit in plastic skate wheels. A tubular shouldered split end passing through the inner race provides bearing engagement when spread by retraction of a conically headed rod projecting beyond the split end. A threaded end of the rod projecting beyond tube is retracted by a threaded knob reacting against the end of the tube, and the tube with bearing is retracted by rotating knob fixed on the tube to feed a threaded portion of the tube through a threaded collar reacting against a side of the wheel. For installing a bearing, it is retracted into a press fit cavity in the skate wheel; and for removing the bearing it is oppositely retracted by the same split end tube extension when spread by the conically headed rod and rotated in the collar.
