Abstract
A puller apparatus and method for disassembling a universal joint which has a cruciform spider and two yokes each of which has collars that carry bearing cups mounted upon the opposite arms of the spider. Integral flanges on the cups prevent them from being pulled through the collars. A puller bridge assembly has studs which extend loosely through holes in the cup flange and are screwed into threaded bores in a first collar of the first yoke; and side plates are mounted on the collars of the second yoke. Puller means has a cross head with puller arms that engage the side plates and a driver screw that bears on the bridge plate so that turning the screw separates the first yoke from the first cup. The bridge assembly and puller means are then repositioned and used to remove the second cup from the first yoke, after which the first yoke is removed. The side plates are then removed, journal caps are placed upon the arms from which the first yoke was removed; and the bridge assembly and puller means, with the arms engaging the journal caps, are used to successively remove the cups from the second yoke.
