Abstract
A Coal Mill Road bearing race puller for removing a bearing race from the lower journal housing of a coal mill and a method of removing a roll bearing race are disclosed. The bearing race puller includes a puller base which is receivable within a lower journal housing of a coal mill below a bearing race to be removed and at least one puller segment that is operatively coupled to the puller base so as to extend beyond an outer peripheral edge of the puller base member and under a circumferential lower edge of the race. According to the preferred method of the present invention, a hydraulic jack is fixedly coupled to the puller base member and is used to push/lift the puller base member and attached puller segment(s) out of the lower journal housing and to thereby push/lift the race out of the lower journal housing.
