Step-by-Step Guide to Replacing an Excavator Cylinder Seal Kit

  1. Remove the cylinder from the excavator. Detach any hydraulic hoses and carefully slide the cylinder off its mounts.
  2. Secure the cylinder in a hydraulic press to prevent movement during disassembly.
  3. Remove the gland assembly by loosening the retaining nut using a wrench set.
  4. Use a seal pick tool to carefully extract the old seal kit from the gland.
  5. Clean the inside of the cylinder and gland thoroughly using cleaning solvents to remove any debris or residue.
  6. Install the new seal kit into the gland. Ensure each seal is installed in the correct orientation as per the manufacturer’s specifications.
  7. Reassemble the gland to the cylinder, ensuring all components are properly aligned and secured.
  8. Use a torque wrench to tighten the retaining nut to the manufacturer’s specified torque settings, which typically range between 350-400 Nm depending on the cylinder size.
  9. Reattach the hydraulic hoses and reinstall the cylinder on the excavator.
  10. Test for leaks by running the excavator's hydraulic system and inspecting visually for any fluid discharge around the cylinder.
