Key Notes:

  • Part Number: PS01V00001R300
  • Interchange Number: PS01V00001R400
  • Cylinder Number: PS01V00001F1
  • Bore: 100mm
  • Kit Type: Bore (piston) seal kit — rod seal kit is a separate part number
  • Application: Contains the piston seals required to rebuild the bore end of the boom hydraulic cylinder on the Case CX55B mini excavator
  • Condition: Aftermarket replacement part

Common Use Case or Symptoms: Use when the boom cylinder is drifting down under load or losing lift capacity — symptoms of internal bypass at the piston seals. This bore kit addresses internal leakage at the piston; if oil is weeping from the rod end, the rod seal kit is the correct repair.
