Understanding Part Number Systems
Every generator manufacturer uses a part numbering system to identify components. Understanding these systems helps you find the right parts quickly and avoid costly mistakes.
Cummins Part Numbers
Cummins uses both Fleetguard (Fleetrite) and Cummins part numbers:
- Fuel filters: FF prefix (e.g., FF5052)
- Oil filters: LF prefix (e.g., LF3349)
- Air filters: AF prefix (e.g., AF25079)
- Coolant filters: WF prefix (e.g., WF2074)
- General parts: 6-7 digit numbers (e.g., 3084392)
Perkins Part Numbers
Perkins parts typically use 9-digit numbers (e.g., 26544037, 26560169).
Stamford/Newage Part Numbers
Stamford AVRs have model-specific numbers (e.g., SX460, MX341, AS440).
DeepSea Part Numbers
DeepSea uses the DSE prefix followed by 4 digits (e.g., DSE7320, DSE8610).
Cross-Referencing Between Brands
Many parts have equivalents across brands. For example:
| Cummins | Donaldson | Baldwin | Description |
|---|---|---|---|
| FF5052 | P550455 | BF7787 | Fuel filter |
| LF3349 | P550174 | B37 | Oil filter |
Conclusion
Always keep a record of your part numbers for future reference. When ordering replacements, verify the part number against your equipment manual or consult with your supplier.
