0445120340 Bosch Fuel Injector 837069405 for Fendt Massey Ferguson Valtra AGCO Sisu Engines

Genuine new Bosch 0445120340 CRIN2-16 common rail fuel injector (OE 837069405, Fendt V837069405, Sisu 837069215) for AGCO Power / Sisu Diesel 44 CWA, 49 CWA, 66 CTA, 74 CTA, 84 CTA and 98 CTA engines fitted to Fendt, Massey Ferguson and Valtra agricultural machines. Made in Germany, supplied in the sealed Bosch box together with the nozzle sealing washer and the injector body O-ring, and covered by a 1-year manufacturer global warranty.

The CRIN2-16 is a solenoid-operated injector from the Bosch CRIN line built for heavy-duty and off-highway diesel engines. It meters each injection event electronically, so a healthy unit restores the correct spray pattern, stable idle, full rated power and normal smoke levels on high-hour agricultural engines. This injector is not IMA-coded: it carries no individual injector accuracy code, so nothing has to be written to the engine ECU after installation.

Bosch 0445120340 replaces the earlier Bosch number 0445120063, which is discontinued. The remanufactured Bosch Exchange equivalent of this injector is 0986435547; the unit offered here is the new-build part, not a remanufactured exchange unit.

Also known internationally as: Common Rail Injector (EN), Common-Rail-Injektor / Einspritzduse (DE), injecteur Common Rail (FR), iniettore Common Rail (IT), inyector Common Rail (ES), injector Common Rail (RO) - Bosch 0445120340 for AGCO Power Sisu engines.

Key Features

Product Details

Cross-Reference Numbers

Compare your original part number before ordering. Manufacturers used different injector variants depending on engine build, power rating, emissions stage and production date, so the model name alone is not enough. Identify the part by the number laser-marked on the injector body, by the OE number, by VIN or by the engine serial number.

Vehicle Compatibility

Compatibility must always be verified by the original Bosch part number, the OEM reference number, VIN or engine serial number. Power figures are given in kW as listed by the manufacturer.

Related Diesel Fuel System Parts

The following related diesel fuel system components may be used together with this application depending on engine configuration. Another variant may be the correct one for your engine, so identify each part by the number on the fitted component rather than by the machine model.

Compatibility Note

Please verify your original Bosch number, OEM reference number, VIN number, engine serial number, or the number marked on the original injector before purchase. Do not install the part before checking compatibility. Installed or used fuel system parts may not be eligible for return.

Diagnostic Information

Common Symptoms of Fuel Injector Failure

On AGCO Power 44 CWA to 98 CTA engines a failing CRIN2 injector typically shows as long cranking and hard starting when hot, a shaking or knocking idle that smooths out under load, loss of rated power under heavy draft work, black or white smoke, higher fuel consumption per hectare, and rail pressure or cylinder balance fault codes stored in the engine ECU. Excessive return flow from one injector will also drop rail pressure and can prevent the engine from starting at all.

Installation and System Check

Before any injector is fitted, inspect the fuel system for contamination, whatever caused the original failure. Check the fuel filter and its housing for water, rust, sticky deposits and metal or abrasive particles, and check the inlet screens of the solenoid valves on the pump and rail (fuel metering unit and pressure regulating valve), which trap debris and show contamination early.

Clean or replace every affected component before installation: tank, feed and return lines, filter housing and filters, fuel rail and high-pressure pump. High-pressure lines and connector tubes are replaced rather than cleaned. Flush the system, fit new filters and bleed it to the manufacturer procedure. A high-pressure pump that has released metal particles is only one possible source; poor or contaminated fuel is just as common, typically from improper bulk fuel storage, fuel tanks that are not cleaned periodically, or contaminated containers used for refuelling.

Carry out all testing required to establish that the injectors are the actual cause of the fault before replacing any part. On installation, fit the supplied nozzle sealing washer and injector body O-ring, clean the injector bore in the cylinder head, and tighten the clamp to the manufacturer torque specification.

Installing a new Bosch injector into a fuel system that has not been decontaminated will cause repeat failure within a short running time, and that damage is not covered by the warranty.
