ABSTRACT:
Relates to tooling devices for removing piston pins for automobile engine pistons for repair or replacement and for installing a repaired or new pin in the piston. More specifically, the invention accomplishes these objects without imposing any load on the piston, thus eliminating the possibility of distorting or otherwise damaging the softer piston. Instead, one of the supporting structures of the tool is shaped in a special way to enter the skirt of the piston and underlay the smaller end of the connecting rod in opposing relation to the driving forces tending to advance the piston pin through the bore of the connecting rod either to remove the pin or to install the repaired pin or its replacement. Other features of the invention have to do with the provisions associated with the same tooling device for centering the piston pin in the bore of the connecting rod and for employing the opposite ends of a support block for performing the steps of both removing and installing piston pins in the aligned bores of the piston and connecting rod assemblies.
