🔧 Product Description

Genuine Volvo Penta tab washer from the Marine Propulsion group, weighing 0.020 kg. It supersedes 18663, which was catalogued earlier simply as a washer, so the current part is the locking tab type rather than a plain one. No thread size or fitment is published against it — where the propeller hardware does give a size, 873475 is the M16 tab washer, 873488 the M20 and 873506 the M24.

⚙️ Key Features

  • Marine Propulsion group tab washer
  • 0.020 kg
  • Supersedes 18663, catalogued earlier as a washer
  • No published thread size — order by part number or measure the nut

🔌 Function

Locks the nut it sits under, with a tab bent up against a flat so the nut cannot turn back in service.

⚠️ Common Signs of Failure

  • Tab cracked or broken off at the bend
  • Washer found flattened where the nut has moved
  • Corrosion or erosion around the bore
  • Nut slack on inspection
  • Vibration or knocking from the assembly it retains

🛠️ Service Notes

  • Tab washers are single use — fit a new one whenever the nut is disturbed
  • Measure the nut before ordering, as no thread size is published against this washer
