ABSTRACT:
A tool for installing shrink fit parts formed of a material which is dimensionally stable over a wide range of temperatures having a locating surface on which a part to be shrunk is clamped and having a chamber adjacent the locating surface, which is filled with a cooling media as the part is being shrunk in a source or vat of cooling media, to maintain the part in its shrunken condition after removal from the cooling media. A valve is provided for removing the cooling media from the chamber after the shrunken part is positioned precisely in a second part so that the shrunken part will warm and expand into the second part to form a shrink fit therewith.
