ABSTRACT:
A component for use in a piston pin remover and replacer device for assembling and disassembling the piston pin connection between a connecting rod and a piston head. The component is comprised of a base and an anvil member mounted on the base. The anvil member has a bifurcated portion which is composed of a pair of spaced apart legs which are spaced upwardly from the base. A rim is mounted on the inside part of the legs and extends coextensively therewith. The rim also extends in an arc between the legs at the bight portion of the bifurcated portion. A hollow sleeve member has an opening therein, the extended axis of which extends between the spaced apart legs and is equidistant from the rim throughout all parts of the arc. An arbor member is slidably mounted in the hollow sleeve member. A stop is provided inside the hollow sleeve member and a spring is provided for urging the arbor member to a position extending out of the hollow sleeve member and away from the stop. The arbor member has a pair of spacers thereon, one spacer being reciprocably mounted on the arbor member and the other spacer being removable from a position between the first-mentioned spacer and the free end of the arbor member.
