🔧 Product Description

Genuine Volvo Penta lock nut weighing 0.011 kg and listed for 120 applications across the MD, TMD, AQ, AD, AQAD and D series. It shares its published weight with lock nut 945989, which covers only 2 AQAD applications, so weight does not separate the two — order by part number and application.

🚤 Compatibility

  • Engine Family: MD, TMD, AQ, AD, AQAD, D, TD, BB, TAMD, MS, B, DP, SP, AQD

Full model list at the end of this description.
