Product Description
Caterpillar Fuel-injection nozzle component 522-2882
1. Product Overview
Caterpillar Fuel-injection nozzle component 522-2882 is listed under source title “Adaptor Nozzle Holder”. It is classified for this pilot as fuel-injection nozzle component within the fuel injection system. The source record does not establish an exact engine model. Confirm the complete engine model, serial number, arrangement, and installed reference before ordering.
2. Function and Operating Principle
A fuel-injection nozzle component controls the final discharge and spray formation of pressurized fuel. Nozzle geometry, opening behavior, holder configuration, sealing surfaces, and calibration must match the injection system.
Fuel pressure acts on precision internal surfaces until the nozzle opens and delivers a controlled spray through small orifices. Contamination, deposits, erosion, or wear can change sealing and atomization.
3. Application Status
| Manufacturer / brand | Caterpillar |
|---|---|
| Part number | 522-2882 |
| Component category | Fuel-injection nozzle component |
| System | Fuel injection |
| Evidence level | C — Component identity only |
| Engine application | Not established by the supplied record |
4. Typical Signs That Inspection May Be Required
| Observation | Possible significance |
|---|---|
| Poor spray pattern or leakage during approved testing | May indicate nozzle wear, contamination, or calibration issues. |
| Cylinder imbalance, smoke, or difficult starting | Requires diagnosis of the complete fuel, air, and compression systems. |
| External leakage at the holder or connection | Requires inspection of sealing surfaces and high-pressure connections. |
| Deposits or damaged nozzle tip | May reflect combustion, contamination, or overheating conditions. |
These observations are inspection triggers rather than a confirmed diagnosis. Evaluate the complete engine system and follow the applicable manufacturer service information.
5. Inspection and Replacement Guidance
- Maintain strict cleanliness around fuel-system components.
- Use approved nozzle test equipment and safety precautions.
- Inspect holder, nozzle, seals, connections, and associated injector parts.
- Confirm nozzle and holder pairing, calibration, and engine application.
6. Information Required Before Ordering
- Complete engine or equipment model.
- Engine serial number and arrangement or configuration number.
- Installed part reference and clear photographs of the identification label.
- Installation position and related assembly information.
Compatibility notice: Verify 522-2882 against serial-number-specific parts documentation before purchase or installation. Do not select the component by appearance or part-number similarity alone.
