ABSTRACT:
A method and apparatus for dismounting a trunnion bearing from a universal joint utilizes a plate that is secured to the proximal arm of one yoke of the joint through which dismounting bolts are threaded into contact with the other joint yoke. Further threading of the dismounting bolts into the plate causes the one yoke secured to the plate to move along a pin of a crossed-pin member of the universal joint, bringing a pin end into contact with the trunnion bearing in the distal arm of the one yoke, thereby urging it out from its press-fitted position in that arm.
