⚙️ Key Features

  • Up to 120S-D
  • 0.002 kg
  • 93 applications across six engine series

🔌 Function

Locks the fastener against turning so the joint holds its setting under vibration.

⚠️ Common Signs of Failure

  • Fastener found slack that should have been locked
  • Locking tab cracked or broken away
  • Washer flattened from a previous refit
  • Setting drifting between services
  • Corrosion breaking the washer up

🛠️ Service Notes

  • A lock washer is a single-use item, so fit a new one rather than bending the old tab back

📦 Condition

  • Genuine Volvo Penta part
  • Brand new
  • Supplied in original or equivalent packaging
