How to Cross-Reference Bobcat Oil Filters

Cross-referencing a Bobcat oil filter means matching the OEM part number on your current filter to a compatible aftermarket replacement. This process lets you find filters that meet the same specifications as the original at a lower cost. The key is matching thread size, gasket diameter, and filter media rating to your specific Bobcat model.

Quick Facts

• Common OEM numbers: 6675517 (skid steers), 7012303 (compact track loaders), 6661248 (older models)
• Cross-reference method: Match thread size, gasket OD, height, and micron rating
• Replacement interval: Every 250 hours or per Bobcat's maintenance schedule
• Cost savings: Aftermarket oil filters typically cost 20-60% less than dealer pricing

What Does Cross-Referencing a Bobcat Oil Filter Mean?

Cross-referencing is the process of finding an equivalent aftermarket oil filter using the OEM part number stamped on your original Bobcat filter. Bobcat sources many of its filters from third-party manufacturers like Donaldson and Wix, which means the same physical filter often carries multiple brand numbers.

When you cross-reference, you are confirming that the replacement filter matches these critical specifications:

• Thread size and pitch (must match your engine's filter housing)
• Gasket outer diameter (ensures a proper seal)
• Filter height and canister diameter
• Micron rating and filter media type
• Anti-drain back valve and bypass valve pressure rating

Why Would I Need to Cross-Reference My Bobcat Oil Filter?

The most common reason is cost savings. Aftermarket oil filters that cross-reference to Bobcat OEM numbers are manufactured to meet or exceed the same filtration specifications at a significantly lower price point. For fleet owners changing filters across multiple machines on a regular schedule, those savings add up quickly.

Other reasons include:

• Availability: Dealer stock may be limited or require lead time, while aftermarket equivalents are often available for immediate shipping
• Superseded numbers: Bobcat occasionally updates part numbers when they change suppliers or revise a design. Cross-referencing helps you find the current equivalent if your old number returns no results
• Consolidation: If you run multiple Bobcat models, cross-referencing can reveal which machines share the same filter, simplifying your inventory

Where Do I Find My Current Bobcat Oil Filter Part Number?

The fastest way to identify your current oil filter is to look at the filter itself. According to Bobcat's operator manuals, the OEM part number is printed or stamped on the filter canister. If the label has worn off, check these sources:

• Operator's manual: The maintenance section lists all filter part numbers by service interval
• Bobcat's online parts catalog: Search by model and serial number to find the correct filter listing
• Serial number plate: Located on the left side of the frame (skid steers and CTLs) or right side of the boom base (excavators). Your serial number identifies the exact production run and which filter revision applies to your machine

If you have the old filter in hand, you can also measure the thread size, gasket diameter, and overall height to cross-reference manually.

How Do I Use an Oil Filter Cross-Reference Chart?

A cross-reference chart maps one manufacturer's part number to equivalent numbers from other brands. To use one effectively, follow these steps:

1. Start with your Bobcat OEM part number (found on the filter or in your operator's manual)
2. Look up that number in the cross-reference chart to find the aftermarket equivalent
3. Verify the physical specifications match: thread size, gasket diameter, height, and micron rating
4. Confirm the bypass valve pressure rating is the same (this protects your engine if the filter clogs)
5. Check that the anti-drain back valve is included (prevents dry starts)

Our parts specialists recommend always verifying the physical specs rather than relying solely on a cross-reference number. Manufacturing tolerances can vary between brands, and confirming the dimensions ensures a proper fit on your specific machine.

Which Aftermarket Filters Fit Popular Bobcat Models?

Many of the most popular Bobcat skid steers, compact track loaders, and mini excavators share oil filters within their engine family. This means a single aftermarket filter number often covers multiple models.

For example, machines running the Kubota V2003 or V2403 engine (including the Bobcat S130, S150, S175, S185, and S205 skid steer loaders) all use the same oil filter that cross-references to OEM 6675517. Similarly, the larger M-series machines like the Bobcat S650 skid steer loader and T770 compact track loader share filter specifications.

Are Aftermarket Oil Filters as Good as Bobcat OEM?

Quality aftermarket oil filters are manufactured to meet or exceed OEM filtration specifications. The filter media, gasket materials, bypass valve settings, and anti-drain back valves are all engineered to match the original part's performance.

According to Bobcat's maintenance guidelines, the critical factor in oil filter selection is matching the filtration micron rating and flow capacity specified for your engine. Aftermarket filters that meet these specifications provide equivalent protection. The main difference is price: aftermarket filters typically cost 20-60% less than the same filter purchased through a Bobcat dealer.

From our experience serving equipment owners across North America, the most important factor is sticking to the recommended change interval rather than the brand name on the filter.

How Often Should I Change My Bobcat Oil Filter?

Bobcat's service manual recommends changing the engine oil filter at every oil change interval, which is typically every 250 hours of operation. Some models specify a 500-hour interval for the oil filter while calling for oil changes at 250 hours, so check your specific model's operator manual.

Factors that may require more frequent changes:

• Dusty environments: Construction sites with heavy dust increase contaminant load
• Short operating cycles: Frequent start-stop operation introduces more condensation
• Heavy loads: Sustained high-RPM operation generates more wear particles
• Cold starts: Operating in cold weather increases oil viscosity and filter strain

Combining your oil filter change with Bobcat skid steer parts like air filters and fuel filters into a single maintenance session keeps everything on the same schedule and saves time.

What Happens If I Use the Wrong Oil Filter?

Installing an incorrect oil filter can cause problems ranging from minor leaks to serious engine damage. Here is what can go wrong:

• Wrong thread size: The filter will not seat properly and will leak oil, potentially leading to engine seizure if the oil level drops
• Wrong gasket diameter: An undersized gasket will not seal against the filter housing, causing leaks. An oversized gasket may fold or pinch during installation
• Insufficient filtration: A filter with a higher micron rating (coarser) than specified will allow particles through that can score bearings and cylinder walls
• Wrong bypass valve pressure: If the bypass valve opens at too low a pressure, unfiltered oil circulates through the engine. If it opens at too high a pressure, the filter can collapse under load
• Missing anti-drain back valve: Without this valve, oil drains from the filter when the engine is off, causing a dry start that accelerates bearing wear

Always verify the physical dimensions and specifications before installing any replacement filter. If you are unsure about compatibility, contact us at sales@partsonline.com with your machine model and serial number for fitment verification.

Can I Use a Different Brand Oil Filter on My Bobcat?

Yes, as long as the replacement filter matches the OEM specifications for your model. Bobcat does not manufacture its own oil filters. The company sources them from established filter manufacturers, which means the same filter element is often available under several different brand names.

The key is matching all of the critical specifications: thread size, gasket diameter, filter media micron rating, bypass valve pressure, and anti-drain back valve presence. A filter that matches these specs from any reputable manufacturer will provide equivalent protection for your engine.

Our engine oil filters collection lists aftermarket equivalents by Bobcat OEM part number, making it easy to find the right cross-reference for your machine.

Frequently Asked Questions

How do I verify an aftermarket oil filter will fit my Bobcat?

Compare the thread size, gasket outer diameter, overall height, and micron rating of the aftermarket filter against your OEM filter's specifications. You can also contact our team at sales@partsonline.com with your model and serial number for fitment verification.

Are Bobcat oil filter part numbers the same across all models?

No. Bobcat uses different oil filters depending on the engine platform. Models sharing the same engine (such as the S175 and S185, both running Kubota V2003 engines) typically use the same filter, but always verify using your serial number.

What is the difference between a bypass and full-flow oil filter?

A full-flow filter handles all of the oil flowing to the engine and typically uses a coarser media (20-25 microns). A bypass filter processes a small portion of oil at a finer micron rating (5-10 microns) to catch smaller particles over time. Most Bobcat machines use a full-flow filter with a built-in bypass valve.

Can I use a longer oil filter if it fits the threads?

A taller filter with the correct thread and gasket may physically mount, but it can cause clearance issues with nearby components like hoses, brackets, or the engine compartment panels. Stick to the OEM-specified dimensions for your model.

Where can I find Bobcat oil filter cross-reference information?

Search by your OEM part number on our Bobcat parts page. Our listings include the OEM number each aftermarket filter replaces. You can also email sales@partsonline.com with your OEM number for help finding the right match.

How much can I save using aftermarket oil filters?

Aftermarket oil filters typically cost 20-60% less than the equivalent filter purchased through a Bobcat dealer. For fleet operators changing filters on multiple machines every 250 hours, annual savings are significant.

What should I do if my Bobcat oil filter part number has been superseded?

Superseded numbers happen when Bobcat updates a part design or changes suppliers. Search using both the old and new numbers, or provide your serial number to our parts team. Aftermarket suppliers often list both superseded and current OEM numbers for compatibility.

Should I pre-fill my oil filter before installing it?

Pre-filling the filter with clean engine oil reduces the time your engine runs with low oil pressure during startup. This is a recommended practice for spin-on style filters where the orientation allows it. Fill the filter with clean oil, let the media absorb it, then install.
