Apparatus for disassembling pressed together crankshafts

Abstract

Apparatus for facilitating the disassembly and assembly of a pressed-together crankshaft such as found on a two-stroke engine used in automobiles, motor boats, wave runners, etc. The apparatus includes a crankshaft engagement member rotatably connected to a channel member which includes a fixed abutment plate, a channel having a pair of flanges interconnected by a web portion which is bent outwardly to provide clearance for at least a portion of a crankshaft assembly engaged by the crankshaft engagement member. The engagement member includes a slot for receiving and supporting a crankshaft throw while a pin forming part of the throw is pressed from its operative position. The engagement member includes a second slot for receiving a center portion of the crankshaft assembly while a center shaft member is pressed from its operative position to allow the removal of a crankshaft center support bearing. The crankshaft engagement member may include a third slot for receiving a center portion of a crankshaft assembly having a different configuration. The crankshaft engagement member is rotatable in order to position a selected slot in its operative position. The crankshaft engagement member is replaceable with the engagement member configured to receive a predetermined crankshaft assembly.
