Propeller Removal Procedures:

  1. Place the Propeller in the Feathered Position:
    • There are two methods:
      • Normal Procedure:
        • Operate the engine at normal idle.
        • Move the propeller pitch lever to the feathered position while simultaneously adjusting the mixture control to idle cutoff.
      • Alternate Procedure:
        • Turn off the magneto switches.
        • Adjust the propeller lever to the feathered position.
        • Remove the spinner
        • For feathering, insert a screwdriver under each HIGH RPM – LOW PITCH stop pin and force the pins up to feather.
  2. Remove Spinner:
    • If not already done, begin by removing the spinner to access the propeller hub.
  3. Remove Cowling:
    • If not already done, remove the cowling to access the propeller.
  4. Drive Dowel Pins:
    • Using a brass drift punch, carefully drive the dowel pins from their holes in the propeller hub flange.
  5. Place Drip Pan:
    • Position a drip pan to catch any fluid or debris during the removal process.
  6. Cut Safety Wire and Remove Attaching Bolts:
    • Cut the safety wire and remove the six attaching bolts securing the propeller.
  7. Remove the Propeller:
    • Lift and remove the propeller from the crankshaft, ensuring proper handling.
    • A bucket can be used as a drip pan by placing the propeller with engine side down.
  8. Cover Crankshaft Opening:
    • Protect the crankshaft opening with a clean rag or cover to prevent debris accumulation.

Propeller Installation Procedures

Installation: Follow these steps to reinstall the propeller and ensure proper functionality.

  1. Clean Propeller Hub and Crankshaft Flange:
    • Use a clean rag to wipe the propeller hub and crankshaft flange, removing any debris.
  2. Install New O-Ring:
    • Install a new O-ring at the base of the flange on the crankshaft’s stub shaft.
  3. Install Dowel Pins:
    • Insert dowel pins through the propeller hub flange holes, ensuring proper alignment.
  4. Position and Attach Propeller:
    • Carefully position and attach the propeller with six bolts and washers, following torque specifications.
    • Torque the bolts to 75 ft-lbs, or to manufacture specifications, and safety wire the bolts
  5. Drive Dowel Pins:
    • Use a brass drift punch to drive the dowel pins flush with the propeller hub flange surface.
  6. Secure Spinner:
    • Finally, secure the spinner to the spinner bulkhead to complete the installation process.

By following these instructions, you can safely and effectively perform propeller removal on a Cessna 310E aircraft. For more detailed guidance, refer to the aircraft’s maintenance manual or consult with a certified aviation technician.
