Abstract: A tool including a core ring having a first end, an opposing second end, and a first radial engagement component. The tool also includes a pin including a shaft having first and second sides. The first side of the shaft is disposed at least adjacent an opening through the ends of the core ring. A second radial engagement component of the pin is configured to engage with the first radial engagement component of the core ring. The second side of the shaft extends axially outwardly from the second end of the core ring. A sleeve is connected to the core ring. The first side of the shaft of the pin is slidable with respect to the sleeve. The sleeve and the core ring together are axially shiftable relative to the pin. At least a portion of the sleeve extends axially outwardly from the first side of the core ring.

Abstract: A tool includes a core ring including a first end and an opposing second end. An opening is defined through the first and second ends. The core ring includes a first radial engagement component. The tool also includes a pin including a shaft having first and second sides. The first side of the shaft is disposed at least adjacent the opening of the core ring. The pin further comprises a second radial engagement component configured to engage with the first radial engagement component of the core ring.

The first side of the shaft of the pin is slidable with respect to the sleeve. At least a portion of the sleeve extends axially outwardly from the first side of the core ring.

Abstract: A system and method for controlling a hydraulic fracturing pumping system is described herein. The method can include stopping an engine coupled to a hydraulic fracturing pumping system including at least one pump by supplying pressure from an accumulator to a hydraulic braking system including a brake. The method can also include starting the engine coupled to the hydraulic fracturing pumping system and releasing the brake.
