3801403 Unit Injector Exch | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta remanufactured unit injector for the TAD1250VE, TAD1251VE and TAD1252VE engines, weighing 1.222 kg across four applications. It is listed alongside long block 3801425, cylinder head 3803924 and turbocharger 3802154 on the same engines. Reman components are restored to technically new condition, with wear parts and anything outside tolerance replaced by new genuine parts, built to a bill of material carrying all design changes so the unit meets the latest technical specification, then tested and painted before despatch. This is an exchange item: core deposit 3804403 is charged alongside it and refunded as soon as the worn injector is returned, and the core can go back once the new one is fitted and the engine is running again.

⚠️ Common Signs of Failure

• Rough idle, misfire or a knock from one cylinder
• Black or white smoke and rising fuel consumption
• Hard starting, particularly from cold
• Excess fuel returning to tank, or fuel dilution of the engine oil
• Worn nozzle holes, a leaking seat or a seized needle found on test

🛠️ Service Notes

• Replace injectors as a set where one has failed on wear rather than damage, so delivery stays even across the cylinders
• Renew the injector seals and copper washers, and check the injector bore in the head is clean before fitting
• Core deposit 3804403 is charged with this order and refunded when the worn injector goes back - the return can wait until the new one is fitted and the engine is running again
