Owning a Bobcat Compact Track Loader (CTL) means having one of the most versatile machines on the market. But whether you just bought a used T190, you are trying to insure a new T770, or you are simply looking to download the correct service manual, everything starts with one specific code: The Product Identification Number (PIN), commonly known as the serial number.
While Bobcat loaders are instantly recognizable by their white and orange livery, identifying the specific generation and production sequence of your machine requires finding the data plate. This can be difficult on older machines where mud, grease, and paint refurbishments have hidden the tags.
In this guide, we will cover the exact locations of the serial number plates on every generation of Bobcat Track Loader, how to distinguish the Machine VIN from the Engine ID, and what to do if your plate is missing or unreadable.
The Short Answer: Where is the Serial Number?
For the quick answer on most models.
On the vast majority of Bobcat Compact Track Loaders (including the popular T590, T650, and T770), the serial number plate is located on the exterior of the loader frame on the operator’s right-hand side.
To locate it:
- Stand on the ground on the right side of the machine (the passenger side).
- Look at the vertical face of the black steel frame.
- The plate is typically riveted at knee-level, just behind the bucket linkage and forward of the rear drive sprocket.
Detailed Locations by Bobcat T-Series Generation
Bobcat has evolved their track loader designs significantly over the last 20 years, moving from the 864 series to the K-Series, M-Series, and now the R-Series. Depending on the age of your machine, the location may vary.
1. M-Series and R-Series (Newer Machines)
Common Models: T450, T550, T590, T650, T750, T770, T870.
For modern machines, Bobcat standardized the location to make it accessible for inspectors and owners.
- Primary Location: The exterior right-hand frame rail. It is a rectangular plate, usually silver or black, with the PIN stamped clearly.
- Secondary Check: If you have a keyless start panel (Deluxe Instrumentation), the serial number is often stored digitally. You can view it by navigating to the "Machine Info" section on the display screen.
2. K-Series and Early T-Series (The "Classic" Models)
Common Models: T180, T190, T250, T300, T320.
The T190 and T300 are two of the most common track loaders ever built. If you have one of these units, the plate is almost always on the exterior right-hand upright.
- The "Hidden" Location: On some earlier production runs of the T190, the plate was placed inside the engine bay to protect it from debris. Open the rear tailgate and check the inner steel wall on the right side.
- Inside the Cab: Check the "kick plate" below the operator seat. On older units, there is sometimes a stamped metal tag riveted to the riser between the operator's feet.
3. The 864 Series (The First Track Loader)
Before the "T" designation, Bobcat produced the 864. On these vintage machines, check the front of the main frame, between the lift arms, or look inside the cab on the glove box door.
The Critical Difference: Machine VIN vs. Engine ID
One of the most common points of confusion for new owners is the presence of multiple serial numbers on a single machine. It is vital to know the difference between the Machine PIN and the Engine Tag.
1. The Machine PIN (The VIN): This is the 9-digit alphanumeric code (e.g., A3L112345) found on the frame.
- What it identifies: The entire machine assembly, including the chassis, cab, and hydraulic system.
- When to use it: For insurance, theft recovery, title registration, and identifying the model year (via a dealer).
2. The Engine Serial Number: This is found directly on the engine block (Kubota, Perkins, Deutz, or Bobcat/Doosan).
- What it identifies: Only the engine itself.
- When to use it: Only when performing internal engine work (like rebuilding a cylinder head or replacing injectors).
Tip: If you use the Engine Serial Number to register your machine for insurance, you are technically insuring the motor, not the loader. Always hunt for the Frame PIN.
Why Do You Need Your Serial Number?
Even if you aren't ordering parts today, knowing your serial number is an essential part of equipment ownership.
1. Identifying the Year of Manufacture: Unlike a car, a Bobcat serial number does not have a simple "Year Digit." You cannot look at the 10th digit to see if it’s a 2015. The 9-digit code represents a Production Sequence. To find out the exact year your machine was built, you will need to provide this 9-digit number to a local dealer or lookup service to decode the manufacture date.
2. Buying or Selling Used Equipment: If you are looking to buy a used T590 from a private seller, checking the serial number is your first line of defense.
- Match the Paperwork: Ensure the PIN on the frame matches the PIN on the Bill of Sale.
- Check for Tampering: If the serial number plate has been drilled out, scratched off, or painted over heavily, be cautious. This is a red flag for stolen equipment.
3. Theft Recovery: Construction equipment theft is a major issue. We recommend taking a clear photo of your serial number plate and saving it to your phone or cloud storage. If your machine is ever stolen, the police and insurance adjusters will require this specific 9-digit code to file a report.
What if the Serial Number Plate is Missing?
Track loaders operate in harsh environments like forests, demolition sites, and mud. It is very common for the external plate to be sheared off by a tree branch or rock. If you cannot find the sticker, do not panic.
- Look for the Stamp: Bobcat almost always stamps the serial number directly into the steel chassis underneath where the plate was riveted. You may need to use a wire brush, sandpaper, or paint thinner to reveal the metal stamping.
- Check the Stamped Locations: On T-Series loaders, check the top of the fuel tank (under the cab) or the main frame rails inside the engine compartment.
- Electronic Display: As mentioned, newer machines store this data in the ECU. If the machine powers up, you can retrieve the ID digitally.
Summary
Finding the serial number on your Bobcat Compact Track Loader is the first step in responsible ownership. Whether you are verifying a purchase, setting up an insurance policy, or just building a file for your records, knowing where to look saves time and confusion.
Quick Checklist:
- Location: Exterior frame, Right-hand side.
- Format: 9-Digit Alphanumeric code.
- Verification: Ensure it matches your paperwork and is not the engine tag.

Frequently Asked Questions
Q: How do I tell what year my Bobcat T190 is?
A: You cannot tell the year solely by reading the serial number yourself. The serial number indicates a production sequence. You must contact a Bobcat dealer with your 9-digit PIN, and they can look up the exact "Date of Manufacture" in their system.
Q: Is the serial number the same as the VIN?
A: Yes. In the heavy equipment industry, the terms PIN (Product Identification Number), Serial Number, and VIN are often used interchangeably to refer to the machine's unique 9-digit ID code.
Q: Why does my machine have a different number on the engine?
A: The engine is a component supplied by a specific engine manufacturer (like Kubota or Doosan). It has its own warranty and tracking number, which is different from the chassis number of the loader itself.
