Claims
- 1. A tool for extracting a bearing press fit in a wheel comprising; a tube having a threaded body and a split end for extending through an inner bearing race with shoulder means extending beyond the axial extremity of said bearing race expandable for axial engagement with the axial extremity of said race, a rod extending through said tube with a threaded end and a tapered opposite end for expanding said split end upon tensile retraction, threaded means engaging said threaded end and reacting against an end of said tube opposite said split end for retracting said rod to produce said expansion, and a collar, said collar having an axially extending, inwardly threaded bore therein, said threaded bore complementary with said threaded body of said tube such that rotation of said collar about said tube results in axial displacement of said collar, said collar further including a radially extending portion defining a face transverse said axially extending threaded bore, said collar further having a cylindrical cavity extending axially inward form said face, said cavity of a size sufficient to receive said bearing, wherein said face reacts directly against said wheel for retracting said tube with said split end shoulder means in axial retracting engagement with said race and bearing to effect extraction of said bearing from said wheel.
- 2. Tool of claim 1 including means for also installing a bearing to be press-fit in a wheel, said split end being of sufficient length to extend through the wheel and loose bearing to be installed, and including means for retracting said tube with said split end and bearing into said wheel.
- 3. Tool of claim 1 wherein said rod is provided with a threaded end engaged by a threaded knob reacting against the end of said tube to produce said rod retraction and split end expansion.
- 4. Tool of claim 1 wherein said tube has a threaded body with a reduced unthreaded split end having sufficient length for extension through a wheel and loose bearing prior to installation as well as through an installed bearing prior to extraction.
- 5. Tool of claim 1 including a threaded collar provided, upon rotation engagement by the thread of said tube, for reaction engagement with the side of a wheel.
- 6. Tool of claim 5 including a hand knob secured to said tube for producing feed rotation between said tube and said collar.
- 7. Tool of claim 1 with a shoulder free state outside diameter of approximately 0.270/0.272 inch and a shoulder step of approximately 0.015 inch.
- 8. Tool of claim 7 with a rod head diameter of approximately 0.250 inches, a rod diameter of approximately 0.162/0.165 inches, and a taper of approximately 30.degree..
- 9. Tool of claim 8 with an unthreaded tube end length of approximately 1.5 inches
- 10. Tool of claim 9 with an unthreaded tube end length of approximately 1.5 inches and a base diameter of approximately 0.270 inch.
