how to remove pto clutch bolt

Removing a PTO (Power Take-Off) clutch bolt can require some effort as these bolts are often tightened to high torque specifications. Here are the general steps to remove a PTO clutch bolt:

Materials and Tools You May Need:

  • Socket wrench or impact wrench
  • Appropriate socket size
  • Penetrating oil (e.g., PB Blaster or WD-40)
  • Safety glasses
  • Gloves


  1. Safety Precautions:
    • Put on safety glasses and gloves to protect yourself during the process.
  2. Access the PTO Clutch Bolt:
    • Locate the PTO clutch bolt on your equipment. It may be under a protective cover or housing, so remove any necessary covers to access it.
  3. Loosen the Bolt:
    • Insert the appropriate socket size onto your socket wrench or impact wrench. Ensure it fits snugly on the PTO clutch bolt.
  4. Apply Penetrating Oil:
    • Spray penetrating oil (such as PB Blaster or WD-40) generously onto the PTO clutch bolt and the area around it. Allow it to penetrate and loosen any rust or corrosion for at least 15-30 minutes. Penetrating oil helps to break the bond between the threads.
  5. Attempt to Loosen:
    • Using your socket wrench or impact wrench, attempt to loosen the PTO clutch bolt by turning it counterclockwise (lefty loosey). Apply steady pressure, and if necessary, use short, controlled bursts with an impact wrench to break it loose. Be cautious not to strip the bolt head; if it doesn’t budge, do not force it.
  6. Tap the Bolt (if needed):
    • If the PTO clutch bolt remains stubborn, you can try lightly tapping it with a rubber mallet or a wooden block and a regular hammer. This can help to break any remaining rust or corrosion.
  7. Heat the Bolt (if needed):
    • As a last resort, you can apply heat to the PTO clutch bolt using a propane torch. Heat the bolt for a minute or two, focusing on the area around the bolt and not directly on it. The expansion and contraction caused by heat can sometimes help break the bond. Be extremely cautious when using heat, as it can cause nearby components to become hot.
  8. Loosen and Remove:
    • Once the PTO clutch bolt begins to turn, continue turning it counterclockwise until it’s fully removed. Keep a firm grip on the wrench to prevent injury if the bolt suddenly breaks free.
  9. Inspect and Replace (if necessary):
    • After removing the PTO clutch bolt, inspect it for damage. If it’s damaged or worn, replace it with a new bolt of the same specifications.
  10. Reassemble:
    • If you had to remove any protective covers or housings to access the bolt, reassemble them properly.

Remember that PTO clutch bolts can be challenging to remove due to the high torque and exposure to the elements, so patience and persistence are key. If you encounter significant difficulties or concerns during the process, it may be advisable to seek assistance from a professional or consult your equipment’s manufacturer for guidance.
