🔧 Product Description

Genuine Volvo Penta M6 lock nut weighing 0.002 kg and listed for 464 applications including MD, TMD, AQ, AQD, TD and AD series units. It consolidates five earlier numbers — 831869, 831868, 831870, 850413 and 876255. Lock nut 963104 is the M5 size and carries the same published weight, so order by the thread, not by mass.

🚤 Compatibility

  • Engine Family: MD, TMD, AQ, AQD, TD, AD, TAMD, D, AQAD, TWD, TID, BB, THAMD, MS, B, DP, SP, HS, TAD, MB, KAD, KAMD
  • HP Range: 40-435 HP

  • 464 listed applications
  • Consolidates 831869, 831868, 831870, 850413 and 876255

🔌 Function

Clamps a joint from the opposite face and resists loosening under vibration through its locking feature.

⚠️ Common Signs of Failure

  • Nut spinning down the thread with no drag
  • Joint working loose under vibration
  • Nylon insert lost, melted or heat-glazed
  • Stripped or galled thread
  • Rounded flats after removal

🛠️ Service Notes

  • Order by thread size — M6 here against M5 for 963104
  • Renew rather than reuse: a lock nut that goes on easily has nothing left to lock with
