Exercise machines, crankshaft assemblies for exercise machines, and methods of disassembling exercise machines having crank arms

A crank assembly for an exercise machine, the crank assembly comprising:

• a crankshaft having a crankshaft mounting surface, a landing surface, and a crankshaft bore;
• a crank arm having a threaded crank arm bore and a crank arm mounting surface that is frictionally engaged with the crankshaft mounting surface;
• a fastener that axially extends through the threaded crank arm bore and into engagement with the crankshaft bore to fasten the crank arm to the crankshaft;
• and
• a removal tool having a threaded shaft with a larger diameter than a threaded shaft of the fastener,
• wherein the threaded crank arm bore is configured for threaded engagement by the removal tool such that removal of the fastener and insertion and rotation of the removal tool in the threaded crank arm bore causes the removal tool to disengage the crank arm mounting surface from the crankshaft mounting surface and thus facilitates removal of the crank arm from the crankshaft.
