Identifying the Model Year of a Ford 555 Backhoe Loader

[MikePhua]

The Ford 555 backhoe loader, produced from 1978 to 1995, is a versatile and durable machine widely used in construction, agriculture, and municipal projects. Determining the exact model year of a Ford 555 can be challenging due to the lack of a standardized VIN system and the potential for worn or missing serial number plates. However, by examining specific identifiers and understanding the production timeline, one can accurately ascertain the model year.
Serial Number Ranges by Model Year
Ford utilized a sequential serial number system for the 555 series. Each model year corresponds to a specific range of serial numbers:

• 1978: C579970 – C586057
  
• 1979: C586058 – C636721
  
• 1980: C636722 – C665879
  
• 1981: C665880 – C687202
  
• 1982: C687203 – C696237
  
• 1983: C696238 – C711238
  
• 1984: C711239 and later
  

These serial numbers typically start with a "C" followed by six digits. The serial number plate is usually located on the left side of the engine block or right side of the transmission housing, below the operator platform.
Decoding the Model and Unit Numbers
In addition to the serial number, Ford 555 backhoes have model and unit numbers that provide further insight into the machine's specifications and manufacturing details. The model number is often stamped on the machine's ID plate, typically located on the left side of the steering cowling or near the operator's seat.
For example, a model number like DF311F can be broken down as follows:

• D: Indicates the model series (in this case, 555).
  
• F: Denotes the transmission type (e.g., 4x4 torque converter auto-reversing transmission).
  
• 311: Represents the engine type (e.g., diesel engine).
  
• F: Specifies additional features or configurations.
  

The unit number, typically a five-digit code, can also provide date information. For instance, the first digit often represents the year of manufacture, the second digit indicates the month, and the remaining digits are sequential. This system can help pinpoint the exact production date of the machine.
Consulting Ford's Manufacturing Records
If the serial number plate is missing or illegible, and the model/unit numbers are insufficient for identification, contacting a Ford dealer with the engine or component numbers can be helpful. Dealers have access to Ford's manufacturing records and can assist in determining the model year based on these identifiers.
Conclusion
Accurately identifying the model year of a Ford 555 backhoe loader is crucial for maintenance, parts replacement, and resale purposes. By examining the serial number, model/unit numbers, and consulting Ford's manufacturing records when necessary, owners and operators can determine the exact model year of their machine. This knowledge ensures proper maintenance and the availability of compatible parts, contributing to the longevity and efficiency of the backhoe loader.
