0445124041 Bosch Fuel Injector 04515158 for Deutz TCD 6.1 Fendt 800 Vario Deutz-Fahr Agrotron 7250 TTV

Genuine new Bosch 0445124041 CRIN3-20/22 common rail fuel injector (OE 04515158, Deutz-Fahr 04504666, Fendt F836200710460) for the Deutz TCD 6.1 L06 six-cylinder engine fitted to the Fendt 819, 822, 824, 826 and 828 Vario tractors of types 832 to 836, the Deutz-Fahr Agrotron 7250 TTV, the Deutz-Fahr 6060 HTS combine harvester and the Lamborghini Mach 250 VRT and R6.250 VRT. 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 CRIN3-20/22 is a solenoid-operated injector from the Bosch CRIN heavy-duty line. It meters each injection event electronically, so a healthy unit restores the correct spray pattern, a stable idle, full rated power and normal smoke levels on high-hour agricultural engines. This injector is IMA-coded: it carries an individual IMA calibration code laser-marked on the solenoid cap, describing that injector's exact actuation timing and injected fuel quantity, and that code must be written into the engine ECU after installation so the ECU can drive it precisely.

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 0445124041 for Deutz TCD 6.1 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, 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.

Fendt Applications

Important for Fendt 800 Vario owners: Fendt used the same model names 822, 824, 826 and 828 Vario on two different tractor generations. This injector is for the earlier generation, Fendt types 832 to 836. The later generation, Fendt types 839 to 842, uses a different injector, Bosch 0445124023 (Deutz 04511509). Read the type number on the tractor identification plate or the number marked on the fitted injector before ordering.

Deutz-Fahr Applications

Lamborghini Applications

Several production generations exist within these model ranges, and the injector was not carried over unchanged across all of them. Confirm the fitment by the number marked on the injector fitted to your engine, or by the engine serial number, not by the machine model alone.

Technical Information

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 the Deutz TCD 6.1 L06 a failing CRIN3 injector usually shows as extended cranking and hard hot starting, a rough or knocking idle that smooths out under load, loss of rated power in heavy draft work on the Fendt 800 Vario or Agrotron 7250 TTV, black or white smoke, higher fuel consumption per hectare, and rail pressure or cylinder balance diagnostic trouble codes stored in the engine ECU. A single injector with excessive return flow will also pull rail pressure down and can produce a no-start condition. A professional fuel-system test must be carried out before replacing any parts, to confirm the injector is the actual cause of the fault.

Installation and System Check

A fuel system contamination check is mandatory before any injector is fitted, whatever the cause of the fault appears to be. Inspect the fuel filter and its housing, and the inlet screens of the solenoid valves on the pump and on the rail, the fuel metering unit and the pressure regulating valve, because that is where debris collects and where sticky deposits show first.

Clean or replace every affected component: tank, feed and return lines, filter housing and filters, fuel rail and high-pressure pump. High-pressure lines and connector tubes such as F00RC00311 are replaced, not cleaned. Flush the system, fit new filters and bleed it to the manufacturer procedure.

Debris from a failing high-pressure pump is only one cause. Poor quality or contaminated diesel is just as common, typically from improper fuel storage, 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. Write the individual injector code of the new unit into the engine ECU with a diagnostic tool. 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.
