Scrap Shear Retrofit

Back to Case Studies


A scrap processing company’s scrap shear was experiencing much down time and components were continually failing. The shear manufacturer was no longer in business and no prints were available.


  • An exhaustive study of the application was done. Including all component specifications.
  • The equipment was observed in operation and production and maintenance personnel were consulted as correct operation sequence functions were determined.
  • A course of action which included:
    • Identification of failed components
    • Upgrade in filtration
    • Creation of a complete hydraulic schematic.
    • Increased size of hydraulic cylinder.
  • Maintenance and production personnel were trained in the function, proper maintenance and troubleshooting procedures of all components.


  • Operation produced more in one shift than it had been in two shifts.
    • Second operating shift was eliminated (2 people)
  • After two years the shear had yet to have one hydraulic component failure.
