1. A hydraulic power tool comprising:
a housing defining a cylinder;
a piston at least partially positioned within the cylinder and movable between a retracted position and an extended position;
a clevis supporting a head of the power tool;
a nut coupled to an outer peripheral surface of the clevis; and
a collar coupled to the housing and surrounding the nut to axially constrain the nut between the collar and the housing while permitting relative rotation between the collar and the nut.
