0445020533 Bosch CP4 Fuel Injection Pump for Same Deutz-Fahr FARMotion Engines

Genuine new Bosch 0445020533 CP4 high-pressure fuel injection pump (OE 246192950, also written 24619295.0 by SAME Deutz-Fahr) for SDF FARMotion diesel engines fitted to SAME Dorado Natural and Frutteto Natural tractors and Deutz-Fahr 5 series tractors. Manufactured by Bosch in the Czech Republic and supplied in the sealed Bosch box, this is a direct OEM-quality replacement, not a remanufactured exchange unit.

The 0445020533 is a single-piston CP4 pump (Bosch type formula CR/CP4N1/L50/20) driven from the engine timing gear. It raises fuel to common rail pressure and, through its electronic metering unit, delivers only the quantity the ECU demands, so rail pressure stays stable across the load range. The same pump serves both the 3-cylinder FARMotion 35 (2.9 L) and the 4-cylinder FARMotion 45 (3.85 L) engines; it is the rail and injector count that differ between them, not the pump.

Also known internationally as: Common Rail High-Pressure Pump (EN), Common-Rail-Hochdruckpumpe / Einspritzpumpe (DE), Pompe haute pression Common Rail (FR), Pompa alta pressione Common Rail (IT), Bomba de alta presion Common Rail (ES), Pompa de inalta presiune Common Rail (RO) - Bosch 0445020533 for SDF FARMotion engines.

Key features

Product details

OEM cross-reference numbers

Compare your original part number before ordering. The machine model alone is not sufficient to confirm compatibility - manufacturers fitted different pump variants depending on engine build, power rating, emissions stage and production date. Always check the number on the pump installed on your engine.

Vehicle and machine compatibility

Compatibility must always be verified by the original Bosch number, OE number, VIN, engine serial number or the identification number on the pump fitted to your machine. The model alone is not sufficient. The applications below are confirmed fitments; the SDF FARMotion engine family is wider than this list, so if your model is not shown, send us the number from your pump or your machine serial number and we will check it for you.

Technical information

Related diesel fuel system components (SDF FARMotion common rail system)

The following genuine Bosch components belong to the same FARMotion common rail system. The rail differs between the 3-cylinder and 4-cylinder engines. Manufacturers used different variants depending on engine build, model, power rating, emissions stage and production date, so another code may be the correct one for your machine. Identify each part by the number printed on the component fitted to your engine, not by the machine model.

Compatibility note

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

Frequently asked questions

How do I know the Bosch 0445020533 fits my SAME or Deutz-Fahr tractor? Confirm by the Bosch number printed on the pump you are removing (0 445 020 533), or by the SDF OE number 246192950 on the pump label. It is fitted to SAME Dorado Natural and Frutteto Natural tractors and to Deutz-Fahr 5 series tractors with FARMotion engines, but the machine model alone is not enough - always check the number on your original pump. If you are unsure, send us your machine serial number and we will check it.

Is this pump new or remanufactured? It is a genuine new Bosch pump, made in the Czech Republic and supplied in the original sealed Bosch box. It is not a remanufactured exchange unit.

Is OE 246192950 the same as this part? Yes. 246192950 is the SAME Deutz-Fahr original-equipment reference for Bosch 0445020533. SDF also write it as 24619295.0, and the Bosch pump label carries it as 246192950_10. All refer to this pump.

Why does the same pump fit both 3-cylinder and 4-cylinder engines? The CP4N1 is a single-piston pump that supplies a rail, not individual cylinders. It has the capacity for both the 3-cylinder FARMotion 35 (2.9 L) and the 4-cylinder FARMotion 45 (3.85 L), so SDF used one pump across both. What changes between them is the rail - 0445223012 on the 3-cylinder, 0445224092 on the 4-cylinder - and the number of injectors.

What does the CR/CP4N1/L50/20 type formula mean? It is the Bosch internal designation for this pump build: a common rail (CR) CP4 pump in the N1 single-piston variant. It is printed on the pump label under the part number and confirms you are looking at the correct pump family.

My pump looks the same as a 0445020516. Are they interchangeable? No. The 0445020516 is a closely related CP4N1 build (type formula CR/CP4N1/L50/20-S) but it is a different pump for the FPT F5 engine family, with a different OE reference. The two look similar and the type formulas differ by one character, so order by the number on your own pump, not by appearance.

Which injectors and rail go with this pump? On this FARMotion system the injector is Bosch 0445110605 (CRI2-20 OHW), with rail 0445223012 on 3-cylinder engines or 0445224092 on 4-cylinder engines, plus rail pressure sensor 0281006416 and metering unit 0928400821. Variants exist depending on engine build and production date, so identify them by the numbers on the parts fitted to your engine.

What causes a CP4 pump to fail? The CP4 is lubricated by the diesel it pumps, so poor fuel quality, water in the fuel, contamination, air ingress or a neglected fuel filter are the usual causes. Running the tank dry is also damaging, because it removes lubrication from the pump.

Can a failed CP4 pump damage the injectors and rail? Yes. When a CP4 fails internally it can release metal debris into the high-pressure side of the system. In that case the injectors, rail, lines, filter housing and tank must be inspected and cleaned or replaced, otherwise a new pump can fail again quickly.

Do I need to program anything after fitting the pump? The pump itself is not individually coded like an IMA injector, but the fuel system must be correctly bled and the rail pressure checked with diagnostic equipment after installation.

What is included and how is it packed? You receive one Bosch 0445020533 high-pressure pump (3.14 kg) in the original sealed Bosch packaging, boxed at 40 x 30 x 30 cm.

Do you ship worldwide? Yes, we ship worldwide.

Common symptoms of a failing CP4 injection pump

On SDF FARMotion engines a worn or failing 0445020533 typically shows as long cranking or a no-start, an engine that starts and dies, loss of power under load, unstable rail pressure or low-rail-pressure fault codes, and in later stages metal debris found in the fuel filter. Because these symptoms overlap with injector, metering-unit, rail-sensor and fuel-supply faults, have the fuel system tested before replacing the pump. If the old pump failed internally, flush and inspect the full high-pressure circuit first - fitting a new CP4 into a contaminated system is the most common cause of a repeat failure.
