Bosch original 0414702003 Fuel Injector Common Rail Injector for FM FH D12 Diesel Motor Replacement for OEM 0414702005 0414702021 20440409 5237322 original new injector

Engineered specifically around the Volvo D12 engine architecture, the BOSCH 0414702003 unit injector delivers the precise fuel metering demanded by D12C340, D12C380, D12C420, D12C460, D12D420 and D12D460 applications. Built to Bosch OE manufacturing standards, this component is a direct fit for the PDE / UIS unit injection system and is fully cross-referenced to 0414702005, 0414702010, 0414702021, 0986441006 and 0986441106 for straightforward procurement and replacement.

This injector integrates precision nozzle technology, hardened internal components and corrosion-resistant materials to maintain high-pressure injection performance under sustained heavy-duty load. Tight manufacturing tolerances and a low-emission design support consistent spray patterns across Volvo FH12, FM12, FL12 and B12 platforms, as well as buses, excavators, wheel loaders, agricultural tractors, harvesters, marine engines and diesel generator sets. Verified Volvo cross numbers 6050251, 5237322, 20381597, 20440409, 3155044, 8113408 and 8170569 confirm exact application matching for fleet and workshop operators.

To maximize service life, inspect fuel filters regularly, use clean diesel fuel, avoid water contamination and monitor injector return flow as part of preventive fuel system maintenance. For diagnostics, use injector bench testing, solenoid resistance testing, leak-off testing, spray pattern analysis, fuel pressure verification, ECU diagnostic scanning and compression verification. This 702-series unit injector offers reliable, OEM-quality performance for industrial diesel operations.
