0445020516 Bosch CP4 Fuel Injection Pump for New Holland Case Steyr FPT F5 3.4L

Genuine new Bosch 0445020516 CP4 high-pressure fuel injection pump (OE 5801470100 / 580 147 01 00, Perkins T412885) for FPT (Fiat Powertrain) 3.4 L F5 four-cylinder diesel engines fitted to New Holland T4 and T5 tractors, Case skid-steer and track loaders, and Steyr Kompakt and Multi 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 0445020516 is a single-piston CP4 pump (Bosch type formula CR/CP4N1/L50/20-S) 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. 0445020516 is the Bosch commercial service (order) number; 0445020508 is the equivalent Bosch number fitted to the engine as original equipment at the factory.

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 0445020516 for FPT F5 3.4 L 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, OEM number, VIN, engine serial number or the identification number on the pump fitted to your engine. The model alone is not sufficient.

New Holland tractors

Case loaders

Steyr tractors

FPT (Fiat Powertrain) industrial engines

Technical information

Related diesel fuel system components (FPT F5 3.4 L common rail system)

The following genuine Bosch components belong to the same FPT F5 common rail system. This engine family was built in two injector and rail configurations, and the machine model alone does not determine which one you have: manufacturers used different variants depending on engine build, model, power rating, emissions stage and production date. 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, OEM 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 0445020516 fits my tractor or loader? Confirm by the Bosch number printed on the pump you are removing (0445020516 or 0445020508), or by the OE number 5801470100 used by Case, Case IH, Iveco and New Holland. It fits many New Holland T4, T5, TD and TK tractors, Case SR, SV, TR and TV loaders and Steyr Kompakt and Multi tractors with the FPT 3.4 L F5 engine, but the machine model alone is not enough - always check the number on your original pump.

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.

What is the difference between 0445020516 and 0445020508? They are the same pump. 0445020516 is the Bosch commercial service (order) number you buy; 0445020508 is the equivalent Bosch number fitted to the engine as original equipment at the factory.

Is OE 5801470100 the same as this part? Yes. 5801470100 (written 580 147 01 00 by Case) is the Case, Case IH, Iveco and New Holland original-equipment reference for Bosch 0445020516. Perkins list the same pump as T412885.

What does the CR/CP4N1/L50/20-S 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 appears on Bosch documentation and confirms you are looking at the correct pump family.

Which injectors and rail go with this pump? The FPT F5 3.4 L engine was built in two configurations: injector 0445110457 or 0445110540 with rail 0445224075, or injector 0445110657 with rail 0445224098. Which one your machine has depends on the 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 0445020516 high-pressure pump (4.5 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 the FPT F5 3.4 L engine a worn or failing 0445020516 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.
