Abstract
A tool assembly for disassembling a crankshaft assembly with a main shaft received within a hollow extension shaft along a shaft axis and coupled thereto via an interference fit, the extension shaft having a fastener slot. The tool assembly includes a main tool body having a central bore, a main tool body inner surface circumscribing the central bore, and a main tool body outer surface having a fastener bore, the central bore dimensioned for axially receiving the extension shaft, with the fastener bore axially aligned with the extension shaft fastener slot. A fastener is concurrently fastenable to the main tool body via the fastener bore and the hollow extension shaft via the fastener slot. An actuator assembly with a linearly-displacing actuating element is coupled to the main tool body and applies a force, via the actuating element, against an end of the main shaft in a direction along the axis.
