955826 Hexagon Nut | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta hexagon nut weighing 0.005 kg and listed for 285 applications across the MD, TMD, D, TD, AQ and AQD families. It consolidates five earlier numbers - 826320, 850803, 850922, 851082 and 921981 - some of which were once catalogued under assembly names rather than as a fastener, among them a bracket, a hydraulic pump and a valve housing.

🚤 Compatibility

• Engine Family: MD, TMD, D, TD, AQ, AQD, TAD, AD, AQAD, TWD, BB, TID, THD, TAMD, THAMD, MS, B, DP, SP, DH, MB

• Flats rounded off by a slipping spanner
• Thread stripped or picked up
• Corrosion locking the nut to the stud

🛠️ Service Notes

• Because several of the numbers it replaces were once whole assemblies, an old order line may have covered more than this nut - check what else the joint needs before fitting
