953063 Stud | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta stud included in the turbo compressor, weighing 0.018 kg and listed for 15 applications across the MD, TMD, AD, AQAD, TAMD and AQD series. It supersedes 833720. The turbocharger note is the identifying detail — the other studs sharing its 0.018 kg weight (953047, 953224 and 953261) serve completely different positions — so order by number rather than by matching the size.
