Bosch original Common Rail Injector Assembly for FH12 FM12 D12 diesel Motor, Fuel Injector 0414702003, cross reference 20440409, replacement for OEM 3155044, for Loader Bulldozer original new injector

Engineered for demanding heavy-duty applications, the BOSCH 0414702003 Unit Injector is a precision-built diesel fuel injection component manufactured to Bosch OE specifications. As part of the Bosch 0414702XXX Series (702 Series Unit Injector Family), it combines fuel pressurization and injection in one compact PDE/UIS assembly, delivering highly accurate fuel metering, optimized atomization, improved combustion performance, lower emissions, and long-term operational reliability.

This injector is widely applied across the Volvo D12 engine platform, including D12C340, D12C380, D12C420, D12C460, D12D420, and D12D460 variants powering Volvo FH12, FM12, FL12, and B12 trucks and buses. Beyond commercial transportation, it also serves excavators, wheel loaders, agricultural tractors, harvesters, marine diesel engines, and diesel generator sets. The unit interchanges with Bosch numbers 0414702005, 0414702010, 0414702021, 0986441006, and 0986441106, and cross-references Volvo OE numbers 6050251, 5237322, 20381597, 20440409, 3155044, 8113408, and 8170569 for straightforward sourcing.

Industrial-grade construction features precision nozzle technology, hardened internal components, corrosion-resistant materials, and tight manufacturing tolerances to withstand sustained high injection pressures. The camshaft-driven mechanism generates extremely high injection pressure, while ECU-controlled solenoid timing promotes efficient combustion with reduced fuel consumption, smoke, and particulate matter. Supplied in new OEM condition with neutral or original packaging, the injector is available for global export with OEM service and bulk order support.
