how to remove pto shaft from gearbox

Removing a PTO (Power Take-Off) shaft from a gearbox can be necessary for maintenance or repairs. Here’s a general guide on how to do it:

Materials and Tools You May Need:

  • Safety glasses and gloves
  • Socket set and ratchet
  • Adjustable wrench or pliers
  • Penetrating oil (e.g., PB Blaster or WD-40)
  • Rubber mallet or hammer
  • Wooden block (optional)


  1. Safety Precautions:
    • Put on safety glasses and gloves to protect your eyes and hands during the process.
  2. Locate the PTO Shaft:
    • Locate the PTO shaft on the equipment or machinery. It’s the shaft that connects the PTO output of the source (e.g., a tractor) to the gearbox.
  3. Secure the PTO Shaft:
    • Before removing the PTO shaft, make sure the source of power (e.g., the tractor) is turned off and the equipment is securely supported to prevent it from moving unexpectedly.
  4. Disconnect the PTO Shaft:
    • Locate the connection point where the PTO shaft attaches to the gearbox or power source. This connection may involve a splined shaft or a locking collar.
  5. Release the Locking Mechanism:
    • If there is a locking collar or set screw securing the PTO shaft, use an adjustable wrench or pliers to loosen and remove it. This will allow the shaft to slide out of the gearbox.
  6. Apply Penetrating Oil:
    • Spray penetrating oil (such as PB Blaster or WD-40) onto the connection point between the PTO shaft and the gearbox. This will help loosen any rust or corrosion and make it easier to remove.
  7. Slide Out the PTO Shaft:
    • Gently pull the PTO shaft out of the gearbox or power source. Depending on the design, you may need to wiggle it or apply slight rotational force to help it slide out.
  8. Use a Rubber Mallet (if needed):
    • If the PTO shaft is stuck, you can lightly tap it with a rubber mallet or a wooden block and a regular hammer to help it disengage from the gearbox. Be careful not to damage the shaft or the gearbox in the process.
  9. Inspect and Clean:
    • Once the PTO shaft is removed, inspect it for any damage or wear. Also, check the connection point on the gearbox or power source for any debris or damage.
  10. Reassemble (if necessary):
    • If you plan to reassemble the PTO shaft, make sure it’s properly lubricated and reattach it to the gearbox or power source, securing any locking mechanisms or set screws as needed.

Always refer to the specific equipment’s user manual or manufacturer’s instructions for detailed information on removing and reassembling the PTO shaft. The design and attachment methods can vary between models, so it’s important to follow the correct procedure. If you encounter significant difficulties or concerns during the process, it may be advisable to seek assistance from a professional or consult the manufacturer for guidance.
