3803730 Injection Pump | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured injection pump weighing 17.5 kg and recorded against 21 applications across the TWD and TD series. The reman catalogue lists it against TAD1230V, and lists 3803701 at 23 kg against the same engine, so the two are alternatives for that build and the engine's parts list has to choose between them. It consolidates 3825472 and 866383, catalogued earlier as an injection pump and a governor, so the governor is now part of the pump. 3803717 at 17.3 kg is only 156 grams away but covers TAD730V, so the designation separates the two. Supplied on exchange: core deposit 3806730 is charged alongside it and refunded once the old pump is returned.
