Abstract
A locking pin tool to facilitate removal and/or installation of locking pins of a well head assembly includes an elongated shaft and a jaw assembly configured for engaging an end of a locking pin. A hammer body is mounted on the shaft and is movable along the shaft. A hammer stop provided on the shaft engages the hammer body to absorb a striking force from the hammer body as the hammer body is moved along the shaft towards the hammer stop. By moving the hammer body along the shaft, the hammer strikes the hammer stop to impart a force on the locking pin to facilitate removal or installation of the locking pin.

A locking pin tool to facilitate removal and/or installation of locking pins of a well head assembly, the locking pin tool comprising:
- an elongated shaft having a longitudinal axis that extends along opposite first and second ends of the shaft;
- a jaw assembly coupled to the first end of the shaft, the jaw assembly comprising a lower jaw body having a lower jaw face and an opposing upper jaw body having an upper jaw face, the lower and upper jaw faces oriented so that the jaw faces face one another, the upper jaw body being movable with respect to the lower jaw body between first and second positions to increase or decrease the distance between the upper and lower jaw faces, the jaw assembly being configured to engage an end of a locking pin when the upper and lower jaw faces are brought together, the jaw assembly further comprising a jaw clamp insert body that is pivotally mounted to the upper jaw body, the jaw clamp insert body having a series of teeth that are longitudinally spaced apart for engaging the end of the locking pin;
- a jaw body fastener for engaging the upper and lower jaw bodies and selectivity tightening the jaw faces against the end of the locking pin to secure the locking pin tool thereon;
- a hammer body mounted on the shaft and being movable along the shaft along lines parallel to the longitudinal axis of the shaft;
- and
- a hammer stop provided on the shaft that engages the hammer body to absorb a striking force from the hammer body as the hammer body is moved along the shaft towards the hammer stop.
