Extension removal tool

A system for disassembling a crankshaft assembly, comprising:

• a main shaft having a main shaft radially outer surface extending from a main shaft first end to a main shaft second end along a shaft axis, the main shaft radially outer surface including a main shaft frustoconical portion along a length of the main shaft, the main shaft being rotatable about the shaft axis and axially fixed in place;
• an extension shaft having an extension shaft central bore, an extension shaft radially inner surface circumscribing the extension shaft central bore, and an extension shaft radially outer surface extending between an extension shaft first end and an extension shaft second end along the shaft axis, the extension shaft radially inner surface including an extension shaft frustoconical portion, the main shaft receivable within the extension shaft central bore with the main shaft frustoconical portion engaging the extension shaft frustoconical portion at a frustoconical linkage, the extension shaft further including an extension shaft fastener slot eccentrically disposed on the extension shaft radially outer surface;
• a main tool body having a main tool body central bore, a main tool body radially inner surface circumscribing the main tool body central bore, and a main tool body radially outer surface having a main tool body fastener bore, the extension shaft receivable within the main tool body central bore with the main tool body fastener bore axially aligned with the extension shaft fastener slot;
• a fastener dimensioned to be concurrently fastened to the main tool body via the main tool body fastener bore and the extension shaft via the extension shaft fastener slot;
• and
• an actuator assembly with a linearly-displacing actuating element operatively coupled to the main shaft first end, the actuator operable to apply a force, via the linearly-displacing actuating element, against the main shaft in a first direction from the actuator assembly towards the main shaft first end along the shaft axis.
