How to Cross-Reference Bobcat Part Numbers

A Bobcat part number cross-reference lets you match an OEM part number to a compatible aftermarket replacement. This is essential when you need to find parts that are no longer stocked by dealers, when original numbers have been superseded, or when you want to save 20-60% by sourcing aftermarket equivalents. The process starts with locating the OEM number on the part itself, your operator's manual, or Bobcat's parts catalog, then verifying the match through physical specifications.

What You Need to Know

• Where to find OEM numbers: Printed on the part, listed in the operator's manual, or available through Bobcat's online parts catalog using your serial number
• Cross-reference tools: Aftermarket supplier catalogs, Parts Online search by OEM number, or direct assistance from our parts team
• Common superseded parts: Filters, cab glass, drive belts, and undercarriage components are frequently updated to new numbers
• When numbers change: Supplier changes, design updates, and part consolidation all trigger new OEM numbers

What Is a Bobcat Part Number Cross-Reference?

Cross-referencing is the process of matching a Bobcat OEM part number to an equivalent aftermarket part. Every component on a Bobcat machine has an OEM number assigned by Bobcat. Aftermarket manufacturers produce the same parts to identical specifications but assign their own catalog numbers.

A cross-reference connects these two numbering systems so you can find the right aftermarket replacement using the OEM number you already know. This works because:

• Bobcat sources many components from third-party manufacturers (Donaldson for filters, for example), so the same physical part carries multiple brand numbers
• Aftermarket suppliers reverse-engineer OEM parts to match dimensions, materials, and performance specifications
• Cross-reference databases map OEM numbers to aftermarket equivalents based on verified specification matching

Where Do I Find the OEM Part Number on My Bobcat?

There are several places to locate the original Bobcat part number for any component on your machine:

• On the part itself: Many components (filters, glass panels, drive belts, electrical parts) have the OEM number printed, stamped, or labeled directly on the part. Check the filter canister, glass edge, or belt sidewall
• Operator's manual: The maintenance section lists all routine service part numbers. The parts section at the back of the manual includes a more comprehensive list organized by system
• Bobcat's online parts catalog: Search by model and serial number to find the exact part listing for your machine's production run
• Serial number plate: While the plate itself does not list part numbers, it identifies your exact machine configuration, which determines which parts revision applies

The serial number plate location varies by machine type. On Bobcat skid steer loaders and compact track loaders, it is typically on the left side of the frame near the rear of the machine. On mini excavators, look on the right side near the base of the boom arm.

Why Do Bobcat Part Numbers Get Superseded?

Supersession is when Bobcat retires an old part number and assigns a new one to the replacement. This happens more often than most owners expect, and it does not always mean the part itself has changed significantly.

Common reasons for supersession:

• Supplier change: Bobcat switches to a different manufacturer for the same component. The part is functionally identical but receives a new number
• Design revision: A minor engineering change (updated gasket material, revised mounting bracket, improved filter media) triggers a new number even if the part is backward-compatible
• Part consolidation: Bobcat merges multiple model-specific parts into a single universal part number that fits a wider range of machines
• Safety updates: Structural or safety-related changes require a new number to ensure the correct revised part is installed

According to Bobcat's parts system, superseded numbers create a chain. For example, an original part number from a 2005 model may have been superseded twice: first to an intermediate number, then to the current active number. Searching the original number in Bobcat's catalog should redirect you to the current replacement.

How Do I Look Up a Bobcat Part Number?

The lookup process depends on what information you have available. Here are the most common scenarios:

If you have the OEM part number:

1. Search the number directly on our Bobcat parts page
2. If the number has been superseded, try searching the new number (Bobcat's online catalog can show you the supersession chain)
3. Our listings include OEM cross-reference numbers, so searching by either old or current numbers will often return results

If you only have the model and serial number:

1. Look up your model in Bobcat's online parts catalog using the serial number to identify the correct parts revision
2. Note the OEM part number for the component you need
3. Search that number on our site or email sales@partsonline.com with the details

If you have the part in hand but no readable number:

1. Measure the part's key dimensions (thread size, diameter, height, mounting bolt pattern)
2. Note any identifying features (color, shape, material, number of mounting holes)
3. Contact our parts team with the measurements, your machine model, and serial number for identification

What Are the Most Commonly Cross-Referenced Bobcat Parts?

Based on our catalog data, these are the part categories most frequently cross-referenced by Bobcat equipment owners:

Part Category	Why Cross-Referenced	Example OEM Numbers
Engine oil filters	High-frequency replacement, easy to cross-reference	6675517, 6661248, 7253841
Hydraulic filters	Multiple filter positions per machine, different part numbers	6661248, 7012303, 7253841
Fuel filters	Regular service item, model-specific numbers	6667352, 7012350, 7253331
Cab door glass	Frequent breakage, M-series vs legacy distinction	7120401, 6729776
Drive belts	Wear item, easily measured for cross-reference	Varies by model and engine
Seals and O-rings	Standard industrial sizes, multiple suppliers	Varies widely
Bucket teeth and edges	High-wear items, aftermarket widely available	6737326 (tooth), varies by bucket

Filters are by far the most commonly cross-referenced parts because they are replaced on a regular schedule and Bobcat sources them from established filter manufacturers whose products are widely available under different brand names.

How Do I Verify an Aftermarket Part Matches OEM?

Cross-reference databases are a starting point, but physical verification ensures the aftermarket part will actually fit and function correctly on your machine.

Verification steps:

1. Compare physical dimensions: Measure thread size, overall dimensions, mounting bolt pattern, and critical tolerances against the OEM part or OEM specifications
2. Check material specifications: For seals, gaskets, and O-rings, confirm the material type (Viton, Buna-N, PTFE) matches the OEM requirement for the application's temperature and chemical exposure
3. Verify performance ratings: For filters, check micron rating, flow capacity, and bypass pressure. For belts, confirm the cross-section profile and length
4. Confirm fitment by serial number: The same Bobcat model can use different parts depending on the production run. Your serial number identifies which revision applies

If you are uncertain about a cross-reference match, email sales@partsonline.com with your model, serial number, and the OEM part number. Our parts team can verify compatibility before you order.

Can I Cross-Reference Parts Between Different Bobcat Models?

Yes, in many cases. Bobcat uses common components across machines that share the same engine platform, cab design, or hydraulic system. This means a part number from one model may fit several others.

Common cross-model compatibility:

• Engine filters: Models sharing the same engine (e.g., Kubota V2003) use the same oil, fuel, and air filters regardless of the machine model
• Cab components: M-series door glass, seals, wiper arms, and latches are shared across the M-series cab platform used on multiple skid steers and CTLs
• Undercarriage (CTLs): Track sprockets, idlers, and rollers may be shared between similar-sized compact track loaders

However, never assume interchangeability without verification. Even within the same model line, serial number breaks can change the parts specification. Browse our Bobcat skid steer parts, compact track loader parts, and mini excavator parts collections to see which parts list multiple compatible models.

What Are Common Bobcat Part Number Formats?

Understanding the format helps you distinguish a genuine Bobcat OEM number from other manufacturer numbers that may be printed on the same part.

• Standard format: 7-digit numeric (e.g., 6675517, 7120401, 7253841). This is the most common format for current Bobcat parts
• Older format: Some legacy parts use a shorter numeric format or include letter prefixes
• Third-party numbers: Because Bobcat sources from other manufacturers, you may also find Donaldson, Wix, or Baldwin numbers on the same filter. These are the supplier's numbers, not Bobcat OEM numbers

When searching for parts, always use the Bobcat OEM number (7-digit format) as your primary reference. Supplier numbers can be used for additional cross-referencing if the OEM number is not available.

What Should I Do If My Part Number Returns No Results?

If searching an OEM number does not return any matches, try these steps:

1. Check for supersession: The number may have been retired. Search Bobcat's online parts catalog to see if a newer number has replaced it
2. Try the supplier number: If the part has a second number from the original manufacturer (Donaldson, Wix, etc.), search that number instead
3. Search by description: If you know the part type and your machine model, search by category (e.g., "S650 hydraulic filter") rather than part number
4. Contact our parts team: Email sales@partsonline.com with your model, serial number, and any part number you have. Include a photo of the part if possible. Our team can identify the correct current replacement

Part number lookups that return no results are often caused by supersession or by searching with a supplier number rather than the Bobcat OEM number.

How Do I Use Serial Numbers to Find the Right Part?

Your Bobcat serial number is the most reliable way to identify the exact parts specification for your machine. Here is why it matters and how to use it:

Bobcat production runs are divided by serial number ranges. Within a single model line, different serial number ranges may use different parts due to mid-production engineering changes. For example, the Bobcat S650 skid steer loader built before a certain serial number may use a different hydraulic filter than one built after that number.

To use your serial number for parts identification:

1. Locate the serial number plate on your machine
2. Record the complete serial number, including any prefix letters
3. Enter the serial number into Bobcat's online parts catalog to see the exact parts list for your specific machine
4. Cross-reference the OEM part numbers with aftermarket equivalents on our site

From our experience serving equipment owners across North America, the serial number lookup resolves the majority of "which part fits my machine" questions. It accounts for mid-production changes that model number alone cannot identify.

Frequently Asked Questions

Are Bobcat OEM part numbers the same as aftermarket part numbers?

No. OEM numbers are assigned by Bobcat. Aftermarket suppliers assign their own catalog numbers to equivalent parts. A cross-reference connects the two systems so you can find the right aftermarket part using the OEM number.

How do I know if a Bobcat part number has been superseded?

Search the number in Bobcat's online parts catalog. If it has been superseded, the catalog will redirect to the current replacement number. Aftermarket suppliers often list both old and new numbers in their cross-reference databases.

Can I use parts from other brands on my Bobcat?

Some components, particularly filters and common hardware, may be interchangeable with parts from other equipment brands if the specifications match exactly. However, this requires careful verification of dimensions, ratings, and mounting compatibility. Always confirm fitment using your serial number.

Where is the serial number plate on my Bobcat?

On skid steers and compact track loaders, the serial number plate is on the left side of the frame near the rear of the machine. On mini excavators, it is on the right side near the base of the boom arm. The plate includes the model, serial number, and manufacturing information.

How do I contact Parts Online for help finding a part?

Email sales@partsonline.com with your machine model, serial number, and the OEM part number (if known). Include a photo of the part or its label if possible. Our team can cross-reference and confirm the correct aftermarket replacement.

Why do some Bobcat models use different parts for the same component?

Engineering changes during a model's production run mean that machines built at different times may use revised parts. These changes are tracked by serial number range. Two machines with the same model number but different serial numbers can require different part revisions.

Does Parts Online's search accept both OEM and aftermarket numbers?

Yes. You can search by Bobcat OEM part number or by aftermarket catalog number. Our listings include cross-reference information to help you find the right part regardless of which number you start with.

What is the fastest way to find the right Bobcat part?

Start with your serial number. It identifies the exact parts revision for your machine and eliminates guesswork caused by mid-production changes. If you have the OEM part number, search it directly. If not, your serial number gives our team everything they need to look it up.
