Abstract
Plug removal and installation tools and methods of operating such to remove suction port plugs and discharge port plugs from a fluid end on a pump (e.g., hydraulic fracturing positive displacement pump) and to insert new plugs are disclosed. The plug removal tool includes a reaction bar assembly, a drive assembly, and a threaded rod assembly. The plug removal tool may be operated by rotating the drive assembly using a high torque, powered impact tool to reduce the time, labor, and fatigue associated with manually removing plugs from a pump using a traditional manually operated plug removal tool. The drive assembly is rotatable independently of the threaded rod assembly and reaction bar assembly. Rotation of the drive assembly results in linear movement of the threaded rod assembly to extend and retract the threaded rod assembly relative to the drive assembly and reaction bar assembly.
