Bosch CP3 Common Rail High-Pressure Fuel Pump Selection Guide

This page provides a practical selection reference for the following Bosch CP3 high-pressure pumps:  0445020081, 0445020082, 0445020152, 0445020110, 0445020089.  It is intended to help buyers match by Bosch part number and OE cross reference to reduce mis-fitment.

1) What is a Bosch CP3 pump?

Bosch CP3 is a common rail high-pressure fuel pump family widely used in heavy-duty diesel engines and off-highway equipment.  Different CP3 variants may look similar but can differ in ports, control configuration, and calibration. For reliable fitment,  always confirm the Bosch number and/or the OE reference from the original pump or OEM catalog.

Important: “Same CP3 type” does not automatically mean interchangeable. Do not select by appearance only.

2) Quick comparison (part numbers)

Bosch 0445020081

• Type: Common rail high-pressure fuel pump (CP3)

• Typical applications: Liebherr engines (off-highway equipment); may appear in some MAN / KAMAZ replacement scenarios (verify carefully)

• Common OE reference: Liebherr 10117814

• Selection note: Prefer OE match or pump tag verification; do not select solely by appearance.

Bosch 0445020082 (MAN)

• Variant: CP3S3/L125/40-789S

• Selection note: YAMZ variants are numerous—confirm engine code + OE to prevent mismatch.

Bosch 0445020089 (KAMAZ/KMZ)

• Variant: CP3S3/L125/40-789S

• Typical engine: KAMAZ/KMZ 11.8L V8 common rail (740.x series)

• Example engine codes: 740.70 / 740.71 / 740.72 / 740.73 / 740.74 / 740.75 (verify exact spec)

• Cross reference / OE: KAMAZ 201149059, 004510411110699088; AZPI A-08-004-00-00-01

• Selection note: Ask for the pump tag photo and engine plate—these platforms often have many similar numbers.

3) What to confirm before ordering

To reduce returns and eliminate fitment risk, request the following from the end user:

1. Pump tag (nameplate) photo showing the Bosch number (0 445 020 xxx).

2. OE reference number from the OEM parts catalog or old component.

3. Engine model / engine plate data (and emissions stage where applicable).

4. Application context (truck, off-highway equipment, industrial engine) to ensure correct configuration.

4) FAQ

Can CP3 pumps be swapped between different part numbers?

Sometimes, but only when the cross reference is explicitly validated and the configuration matches.  Using “CP3” as the only selection criterion is not reliable.

What if the customer only provides the vehicle/equipment model?

Request the engine code and the pump tag photo. Many platforms share similar pump housings while using different calibrations or fittings.

What information is needed to confirm the correct pump?

Ideally: Bosch number + OE reference + engine model. With these, selection can be confirmed quickly and accurately.
