Packing screw removal tool

A system for removing a packing screw, comprising:

• a wellbore pumping unit comprising at least one packing screw having an axis of rotation,
• wherein the at least one packing screw is generally a cylindrical shape having an outer end with a plurality of circumferential holes along an outside diameter;
• a packing screw removal tool comprising:
• a tool body with a plate shape;
• a plurality of packing screw engagement dogs coupled to the tool body, wherein the engagement dogs are oriented parallel to an axis of rotation of the at least one packing screw and configured for an allowance fit over an outer end of the packing screw, and wherein the engagement dogs are asymmetrically disposed about the axis of rotation;
• a plurality of locking pins releasably coupled to the packing screw engagement dogs, wherein the locking pins are oriented in a radial direction relative to the axis of rotation, and wherein the locking pins are configured to extend or retract in the radial direction to engage or disengage the circumferential holes of the at least one packing screw;
• and
• a torque transfer engagement post coupled to the tool body, wherein the torque transfer engagement post extends from the tool body, and wherein the torque transfer engagement post defines a first engagement feature dimensioned to be engaged by a first wrench size.
