ABSTRACT:
This is an apparatus for pulling the bearing cup of a universal joint. It includes a first and a second leg which in operation are each bolted at one end to the yoke arm of a first yoke assembly. The cross bar of a Tee-puller is inserted through rectangular openings in the ends of the legs opposite the end bolted to the yoke arm. Standoff bolts secure a drive bar to one of the yoke arms of a second yoke assembly having the bearing cup which is to be removed. A pusher bolt of the Tee-puller is positioned to contact the drive bar held by the two standoff bolts.
