0445010177 Bosch CP1H3 Common Rail High-Pressure Fuel Pump

The 0445010177 common rail high-pressure fuel pump is a replacement fuel-injection component for diesel applications requiring a compatible high-pressure common rail pump. The product is identified by Bosch reference number 0445010177 and is presented for professional replacement, service, and diesel fuel-system applications.

Product Identification

What This Pump Is Designed to Do

A common rail high-pressure pump supplies pressurized fuel to the common rail system so that the injection system can maintain the pressure and fuel delivery required by the engine control strategy. Correct pump selection depends on the exact pump reference, engine code, fuel-system configuration, mounting interface, fuel connections, and metering-valve configuration.

Application and Compatibility

For 0445010177, buyers should confirm the pump reference number and engine application before ordering. Do not rely on the engine family or vehicle model alone. The recommended verification sequence is:

• Check the number printed on the existing pump or its identification label.
• Confirm the engine code and vehicle/application information.
• Compare the pump mounting points and fuel connections.
• Confirm the metering/control-valve configuration.
• Compare the available OE or manufacturer cross-reference numbers with a current technical record.

Technical Design

The pump should be described using only specifications that are verified for 0445010177. Where the three-plunger CP1H3 configuration is confirmed, the description can state that the pump uses a three-plunger high-pressure pumping arrangement. Avoid describing the same product as a single-plunger pump.

Quality and Functional Testing

Before shipment, the supplier should verify the pump using its applicable inspection and test procedure. Depending on the actual test specification, relevant checks may include pressure build-up, fuel delivery, leakage, metering response, and overall operating stability. Only tests that are actually performed and documented for this product should be stated as completed.

Replacement and Installation Considerations

A high-pressure common rail pump should be installed by a qualified diesel fuel-system technician. Before installation, inspect the fuel system for contamination and confirm that the replacement pump matches the original reference and application. Follow the engine manufacturer's procedures for fuel-system cleanliness, priming, torque settings, and post-installation checks.

How to Confirm 0445010177 Before Purchase

1. Provide a clear photo of the existing pump label or identification plate.
2. Provide the engine model and engine code where available.
3. Provide the vehicle make, model, and production year when relevant.
4. Provide the original pump reference or OE number.
5. Ask the supplier to confirm compatibility before placing the order.

Product-Specific FAQ

What is 0445010177?

0445010177 is the reference number used to identify this common rail high-pressure fuel pump. The exact pump family and application should be confirmed against the pump label and current technical documentation.

Is 0445010177 a three-plunger pump?

It should be described as a three-plunger pump only after the configuration has been verified against the actual product and supplier documentation.

Does 0445010177 fit every TD2200 application?

No universal compatibility should be assumed. Confirm the engine code, original pump number, mounting arrangement, connections, and metering configuration before purchase.

How can I confirm the correct replacement?

Compare the reference number on the existing pump with 0445010177 and provide the engine/application information to the supplier for technical verification.

Should the pump be tested before installation?

A replacement high-pressure pump should be checked according to the applicable supplier and engine manufacturer's procedures, with the fuel system kept clean and properly primed.

Technical Responsibility & Review

Technical information should be reviewed by a qualified product or diesel fuel-system specialist before publication. Record the reviewer, review date, and source of the compatibility data in the internal product record. Update the page when verified specifications or application data change.
