⚙️ Key Features

  • Genuine Volvo Penta hydraulic-pump nut retainer
  • Designed for the engine-driven servo-oil / hydraulic pump
  • Direct service replacement for Volvo Penta part number 20460512
  • Mechanical retainer that prevents the hydraulic-pump shaft or gear nut loosening in service
  • Engine type: 4.0-litre four-cylinder turbocharged industrial diesel

🔌 Function

Mechanically locks the hydraulic-pump shaft or gear nut once it has been tightened, holding the nut against rotation so it cannot back off under the vibration and torque reversals of the pump drive.

⚠️ Common Signs of Failure

  • Retaining nut found loose despite having been correctly tightened
  • Knock or rattle from the pump drive that worsens with engine speed
  • Retainer tab found cracked, sheared or bent flat against the nut
  • Retainer that has already been folded and unfolded, and will not hold again
  • Bright wear marks or debris where the loose nut has been fretting on the shaft

🛠️ Service Notes

  • Confirm thread, length, grade and any single-use restriction against the exact application
  • Clean the threads and use the specified torque, angle and locking method
