[MikePhua]

Introduction to Serial Number Importance
The serial number on heavy equipment like the 2015 CAT 279D skid steer loader is a critical piece of information for owners, operators, and service personnel. It provides essential data about the machine's manufacture, configuration, and history. Accurately identifying the serial number enables efficient parts sourcing, service support, warranty verification, and machine tracking.
Understanding the CAT 279D Serial Number System
The CAT 279D follows Caterpillar’s established serial numbering format, which encodes important details such as model series, manufacturing location, and production sequence. This alphanumeric string is unique to each unit, serving as the machine’s fingerprint.
Key aspects of the serial number include:

• Model Identifier: Typically the first few characters indicating the model type (e.g., "279D").
  
• Factory Code: Indicates the manufacturing plant where the unit was assembled.
  
• Production Sequence Number: A unique numeric portion showing the order of production.
  
• Year of Manufacture: Sometimes embedded within or referenced through the serial number range.
  

Locating the Serial Number on the CAT 279D
Owners or technicians looking to identify the serial number on a 2015 CAT 279D can find it in several standard locations:

• Machine Frame: Usually stamped or affixed on the main frame near the operator’s platform.
  
• Engine Serial Plate: Contains the engine’s own serial number, distinct from the machine’s.
  
• Data Plate: A metal tag attached near the cab or under the hood showing model and serial info.
  
• Operator’s Manual or Documents: The serial number is also recorded in official paperwork and registration.
  

Using the Serial Number for Lookup and Parts Identification
Once the serial number is obtained, it can be cross-referenced with Caterpillar’s databases or authorized dealers to:

• Confirm the exact machine configuration and build options.
  
• Verify warranty status and service bulletins relevant to the serial.
  
• Identify correct parts catalog numbers for repairs or replacements.
  
• Track machine history including previous ownership or recalls.
  

Common Challenges in Serial Number Lookup
Users sometimes face difficulties such as:

• Faded or Damaged Plates: Over time, serial plates may corrode or become unreadable.
  
• Confusion Between Engine and Machine Serial Numbers: It’s important to use the machine’s main serial for parts and service.
  
• Aftermarket or Refurbished Machines: Some units might have altered or missing serial numbers, complicating identification.
  
• Regional Variations: Different countries may have distinct serial number issuance or formats.
  

Additional Tips for Serial Number Verification

• Always cross-verify the serial number on the machine with documentation like purchase invoices or maintenance records.
  
• Use online CAT parts and serial lookup tools provided by dealers for quick reference.
  
• Contact authorized CAT service centers when uncertain about serial number interpretation.
  
• Keep a photo record of the serial plate for future reference and insurance purposes.
  

Terminology Explained

• Serial Number: A unique identifier assigned to each machine for tracking and identification.
  
• Data Plate: A metal or plastic tag affixed to machinery showing key details like serial number, model, and compliance info.
  
• Production Sequence: The incremental number representing the machine’s position in the manufacturing order.
  
• Warranty Verification: The process of confirming if the machine’s warranty is still active based on serial data.
  

Case Example: Serial Number Lookup Helps in Part Replacement
A CAT 279D owner needed to replace the hydraulic pump but was unsure about the exact model variant. By locating the serial number on the machine frame and contacting a CAT dealer, they were able to identify the correct pump part number for their 2015 model. This avoided ordering the wrong part, saving time and additional shipping costs.
Summary of Key Points

• The serial number is essential for precise machine identification, warranty checks, and parts sourcing.
  
• Locate the serial number on the frame, data plate, or documentation for accuracy.
  
• Use authorized CAT resources or dealer support to interpret and use serial information.
  
• Be aware of common challenges such as damaged plates or confusion with engine serials.
  
• Maintaining records of the serial number improves future maintenance efficiency.
  

Conclusion
For owners and operators of the 2015 CAT 279D skid steer loader, understanding and utilizing the serial number is a vital step toward effective machine management. Whether for maintenance, parts ordering, or historical tracking, the serial number provides a gateway to detailed machine information. Proper identification ensures smoother service experiences and better long-term equipment reliability.
