Common Rail Injector System Maintenance BOM - Large Industrial & Marine Engines
| Item | Part Name | Core OEM Part No. / Spec | Functional Description | Unit | Qty (Per Cyl.) | Qty (Full 6-Cyl. Overhaul) | Recommended Replacement Reason & Notes |
|---|---|---|---|---|---|---|---|
| 01 | Common Rail Injector Assembly | F00BJ00071 / 1004135715 | Core injection unit. Atomizes fuel under ultra-high pressure (>2,000 bar). | Pcs | 1 | 6 (or 12 for V12) | Subject to testing results. Can be replaced individually or as a complete engine set. |
| 02 | Injector Lower Copper Washer | Matches specific engine model (thickness varies) | Located at the tip of the nozzle; blocks ultra-high temp & pressure combustion gases. | Pcs | 1 | 6 | Mandatory Replacement. Undergoes plastic deformation under high torque. Reusing it guarantees blow-by gas leaks, melting the nozzle. |
| 03 | Injector Upper O-Ring | High-temp Fluororubber (Viton / FKM) | Seals against the cylinder head top to prevent engine oil from contaminating the diesel return line. | Pcs | 1 | 6 | Mandatory Replacement. Rapidly hardens and ages under prolonged exposure to hot engine oil; must be replaced once disturbed. |
| 04 | Injector Lower O-Ring | High-temp Fluororubber (Viton / FKM) | Works with the upper ring to prevent diesel from seeping into and diluting the crankcase engine oil. | Pcs | 1 | 6 | Mandatory Replacement. Failure leads to fuel dilution of oil, which can cause catastrophic bearing failure or engine seizure. |
| 05 | High-Pressure Fuel Inlet Connector | High-Pressure Feed Tube / Quill Tube | Passes through the side of the cylinder head to link the rail branch to the injector inlet. | Pcs | 1 | 6 (Subject to wear) | If the spherical/conical sealing seat is scratched or distorted during removal, it will leak internally under 2,000+ bar. Replace if worn. |
| 06 | Cylinder Head Cover Gasket | Matches specific engine model drawing | Seals the top valve cover structure to prevent engine oil splashing and weeping. | Pcs | 0.5 | 3 ~ 6 | Large industrial engines often feature "one cylinder, one head" or "two cylinders, one head" designs. Replace the gasket for any cylinder opened. |
| 07 | Heavy-Duty Primary Fuel Filter | High-efficiency water separator (e.g., Fleetguard) | Traps large particulates and removes up to 99% of free/emulsified water from diesel fuel. | Pcs | -- | 1 (Per Engine) | Highly Recommended. Common rail systems are extremely water-sensitive; ensuring pristine filtration protects new injectors. |
| 08 | BOSCH Standard Fine Fuel Filter | Micron-level ultra-high filtration efficiency | Traps sub-micron abrasive particles to protect the highly precise injector needle and valve seat. | Pcs | -- | 1 (Per Engine) | Highly Recommended. Skipping filter replacement may cause brand-new injectors to seize within hours due to contaminated fuel. |
