A rebuild of the Well Stimulation Pump power end will include many key tasks critical to the life and quality of the rebuild, including:     

  • Inspection of many critical tolerances, such as crosshead guide tube minimum I.D., min/max dimensions for interference fit component and crankshaft and pinion floats.        
  • Removal and replacement of wear components lubrication systems such as bearings, gaskets, stay rods, seals, and lube lines.    
  • Replacement of major components such as gears, crankshafts, pinions, and crosshead assembly or frame.


There are three areas to focus on in a power end rebuild that are somewhat unique:   

  • Ensuring that the crosshead assembly moves smoothly.  
  • Ensuring that the float of the pinion and crankshaft have adequate travel to allow for operational movement.  
  • Gear timing.
