3803250 Injector | Genuine Volvo Penta Part

🔧 Product Description

Genuine Volvo Penta Reman injector, listed in Volvo Penta's reman catalogue as the reman injector for the TAMD121C, TAMD121D, TAMD122C, TAMD122D and TMD122A, and weighing 0.354 kg. Five engines on one number makes this the common injector for the 121 and 122 series, and its weight sits in a clear gap between the 0.338 kg injectors below and the busy 0.360 kg band above. Volvo Penta rebuilds the returned core against the current bill of material so it carries the design changes released since the engine was built, replaces wear parts with new genuine parts, then tests and paints the finished injector. It is supplied on exchange: core deposit 3806250 is charged alongside it and refunded once the worn injector is returned, and the core may go back after the new one is fitted and the engine is running again.

🔌 Function

Atomises metered fuel into the combustion chamber at the pressure and spray pattern that cylinder needs.

⚠️ Common Signs of Failure

• A shake at idle that smooths out as the revs come up
• Smoke and a smell of unburnt fuel at the exhaust
• Loss of power and heavier fuel use than usual
• Combustion leaking past the injector seat and sooting the head
• Spray pattern found ragged, or opening pressure low, on test

🛠️ Service Notes

• The TAMD122A takes 3803247 and the TAMD122P takes 3803300, so check the suffix before ordering for a 122
• Injectors are best changed or tested as a set - one fresh nozzle among five tired ones simply moves the misfire
• Core deposit 3806250 is refunded when the old injector goes back, and it can be returned once the engine is running again
