977987 Adjusting Screw | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta adjusting screw weighing 0.082 kg and listed for 23 applications across TMD and TAMD engines. It supersedes 862336, which was catalogued earlier as a plain hexagon screw — so an old parts list may not make clear that the current part is an adjusting screw with a setting function.

• Engine Family: TMD, TAMD
