  • Remove the old cylinder from the office chair using your hands. Put it in the bowl with the nuts you removed earlier. 
  • Using pipe tape, wrap the cylinder and nuts securely from the bowl to the chair. 
  • Place both nuts in your toolkit box for safekeeping. Do not lose them!

Installing The New Cylinder

  • Get a bowl and wrap pipe tape around the cylinder and nuts in a bowl (immediately after removing from a chair), securing it in place on the chair frame. 
  • Pour engine oil all over the cylinder using a rag, then carefully seat it back into the old seat cylinder housing holes. 
  • Holding firmly onto both sides of the chair frame where cylinders were removed, secure two hexagonal nuts back onto the old seat cylinder with new nuts you removed earlier. 
  • Ensure engine oil is covering the cylinder and housing before securing nuts tightly in place.
