Abstract
Abstract A kit for servicing a constant velocity drive shaft, particularly of the type found on General Motors automobiles. A first tool safely removes bearings held by a nylon ring from the yoke without damaging the yoke and includes a stud support member with yoke supports extending upwardly therefrom to engage the yoke, a pair of rods extending upwardly outside the yoke supports and through a top member to threadingly engage nuts for applying force to the yoke. A bushing receiver is mounted on the top member to receive the bearing as it is forced from the yoke. A second tool has a free swinging center for gripping the bearing after it has been pushed out a distance by the first tool. A third tool holds the cross and yoke in alignment during reassembly.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
138 words
A tool for removing bearings having a nylon locking ring from the yoke of a constant velocity universal drive shaft without damaging the yoke comprising: a stud support member; a pair of yoke supports extending upwardly from said stud support member at separated locations to engage said yoke; a pair of rods extending upwardly from said stud support member outside said yoke supports, and threaded on the end opposite said stud support member; a top member having bores through which said rods extend; means mounted on said top member for engaging said yoke about a bearing, and for receiving said bearing; and thrust means engaging said threads on each said rod for applying a force to said top member to cause said nylon locking ring to shear and said bearing to move into said engaging and receiving means.
Claim 2
Dependent Claim
138 words
A tool for removing bearings having a nylon locking ring from the yoke of a constant velocity universal drive shaft without damaging the yoke comprising: a stud support member; a pair of yoke supports extending upwardly from said stud support member at separated locations to engage said yoke; a pair of rods extending upwardly from said stud support member outside said yoke supports, and threaded on the end opposite said stud support member; a top member having bores through which said rods extend; means mounted on said top member for engaging said yoke about a bearing, and for receiving said bearing; and thrust means engaging said threads on each said rod for applying a force to said top member to cause said nylon locking ring to shear and said bearing to move into said engaging and receiving means.
Claim 3
Dependent Claim
38 words
A tool as in claim 1, further including an impact knob mounted on said top member on the side opposite said engaging and receiving means for communicating a shock to said bearing to aid in shearing said ring.
Claim 4
Dependent Claim
19 words
A tool as in claim 1, wherein said yoke supports include means for engaging a cross within said yoke.
Claim 5
Dependent Claim
12 words
