A tool for installing oil or grease seals. The tool includes a cup member with a driving handle at the top thereof. Various sizes of a seal installing member are provided and all have the same upper cylindrical portion with the lower cylindrical portion being of various sizes, depending on the seal with which it is to be used. The tool also includes a pair of extension sleeves, one with an internal rib and the other with an external rib for supporting the cylindrical portions of the sleeve and the installing part when assembled. Each of the second parts and the sleeves include locking pins or slots for receiving the locking pins. The working portion of the tool is the lower annular end face and the cup-like top portion includes a closed face on the top for supporting the tool or one of the extension sleeves.

The invention claimed is: 1. A tool for installing a variety of contoured oil seals in a variety of applications, each application having a right circular cylindrical counter bore of a given inside diameter for receiving a shaft seal, said seal having an elastomeric portion and an embedded metal stiffener therein and presenting an annular end surface of a given size to be engaged by said tool, said tool being a multi-component tool having a first component including a closed end wall with means therein for receiving a drive handle and a pair of right circular cylindrical sidewall surface of given first and second inside and outside diameters respectively and joined by a first flat annular end face surface, at least one locking pin extending inwardly from said first inside diameter sidewall surface, and, nested within said first component, one of several second components each presenting respectively a second flat annular end face defined by third and fourth inner and outer diameter sidewall surfaces, and a third annular end face defined by fifth and sixth inner and outer diameter sidewall surfaces, and at least one locking slot in said second component, said locking slot having a vertical segment intersecting said second annular end face and having a horizontal segment for engaging said locking pin, said second annular end face abutting the first flat annular end face surface of said closed end wall, and said third annular end face surface abutting said end face of said given size on said seal. 2. A tool as defined in claim 1 wherein said tool also includes a pair of extension sleeves, said extension sleeves comprising a first part and a second part, said first part having a pair of annular end faces and an external rib disposed between said faces, and an upper slot for receiving a locking pin and a rib on its interior, an upper, locking pin receiving slot and a lower, inwardly extending locking pin, said second part having a pair of annular end faces, an internal rib, an upper slot for receiving a locking pin and a lower locking pin extending inwardly therefrom, whereby said first and second parts may be locked together and inserted between said first and second components thereby forming an extension sleeve for said components. 3. A tool as defined in claim 1 wherein said means for receiving a drive handle comprises a tapped center opening in said first component. 4. A tool as defined in claim 1 wherein said at least one locking pin comprises two or more locking pins and said at least one locking slot comprises at least two locking slots. 5. A tool as defined in claim 1 wherein there are two locking pins on said first component and two locking slots on said second component. 6. A tool as defined in claim 2 wherein said at least one locking pin comprises two or more locking pins and said at least one locking slot comprises at least two locking slots. 7. A tool as defined in claim 1 wherein said locking slots each comprise an axial opening and a circumferential opening, whereby a twisting motion locks said pin into said opening. 8. A tool for installing a variety of oil seals in a variety of applications, each seal having an elastromeric portion and a metal stiffener embedded therein, each application having a cylindrical counterbore of a given diameter for receiving a given seal, a shaft of smaller given outside diameter over which said seal is installed, said seal presenting a working margin to be engaged by said tool, said tool being a multi-component tool having a first component comprising a continuous cylindrical sidewall of a first inside diameter, a closed end wall portion having means therein for receiving a handle, at least one locking pin mounted on and extending radially inwardly from said cylindrical side wall, and an annular end face for engaging a of said second component, and plural second parts, each of said second parts having one end smaller by a working clearance only than said first inside diameter, said one end extending into said first component and having at least one opening registering with said locking pin and its other end having a cylindrical sidewall of a given outside diameter for pushing said seals into said cylindrical counterbore, said other end having an inside diameter greater than the outside diameter of said shaft, said other end also presenting a working margin for engaging said seal. 9. A tool as defined in claim 8 wherein said means for receiving a drive handle comprises a tapped center opening in said first component. 10. A tool as defined in claim 8 wherein there are two locking pins on said first component and two locking slots on, said second component. 11. A tool as defined in claim 8 wherein said locking slots each comprise an axial opening and a circumferential opening, whereby a twisting motion locks said pin into said opening. 12. A tool for installing a variety of oil seals in a variety of applications, each application having a cylindrical counterbore of a given diameter for receiving a given shaft seal, having an elastomeric portion and an embedded metal stiffener, a shaft of smaller given diameter over which said seal is to be installed, said seal presenting a working margin to be engaged by said tool, said tool being a multi-component tool having a first component comprising a continuous cylindrical sidewall defining an opening of a first inside diameter, a closed end wall portion having means therein for receiving a handle, and at least one locking pin mounted on and extending radially inwardly from said cylindrical side wall, and plural second parts, each second part having a continuous circular sidewall with one end having an outside diameter smaller by a working clearance only than said first inside diameter, said one end extending into said opening in said sidewall of said first component and abutting said closed end wall, and having a slot registering with said locking pin, and the other end of said second component having an inside diameter greater than the outside diameter of said shaft, said other end presenting a working margin adapted to engage said working margin of said seal.
