Reciprocating pump turning and barring tool

A device comprising:

• a reciprocating pump comprising a rotating mechanism;
• a core ring comprising a first end and a second end disposed opposite the first end,
• wherein:
• an opening is defined through the first end and the second end, and
• the core ring comprises a first radial engagement component;
• a pin comprising a shaft having a first side and a second side, wherein:
• the first side of the shaft is disposed through the opening of the core ring,
• the pin further comprises a second radial engagement component configured to engage with the first radial engagement component,
• the second side of the shaft extends axially outwardly from the core ring, and
• the second side of the shaft of the pin is connected to the rotating mechanism;
• a sleeve connected to the first end of the core ring, wherein:
• the first side of the shaft of the pin is disposed at least partially inside the sleeve, and
• the first side of the shaft of the pin is axially slidable inside the sleeve;
• and
• a spring comprising a first face and a second face opposite the first face, wherein:
• the sleeve is connected to the first end of the core ring and extends axially outwardly from the first end of the core ring, and
• the second face of the spring is connected to the sleeve to urge the sleeve towards the pin.

A method of using a device, wherein the device comprises:

• a reciprocating pump comprising a rotating mechanism;
• a core ring comprising a first end and a second end disposed opposite the first end,
• wherein:
• an opening is defined through the first end and the second end, and
• the core ring comprises a first radial engagement component;
• a pin comprising a shaft having a first side and a second side, wherein:
• the first side of the shaft is disposed through the opening of the core ring,
• the pin further comprises a second radial engagement component configured to engage with the first radial engagement component, and
• the second side of the shaft extends axially outwardly from the core ring;
• and
• a sleeve connected to the first end of the core ring, wherein:
• the first side of the shaft of the pin is disposed at least partially inside the sleeve, and
• the first side of the shaft of the pin is axially slidable inside the sleeve;
• wherein the method comprises:
• pressing the sleeve axially towards the pin until the first radial engagement component engages the second radial engagement component;
• and
• turning the sleeve radially, wherein turning the sleeve radially also radially turns the core ring, the pin, and the rotating mechanism of the reciprocating pump.
