How to match Cub Cadet filters to aftermarket and OEM alternatives
A cross reference is a list that shows which filters from different manufacturers will work in your Cub Cadet engine. Cub Cadet makes its own filters and also sources them from suppliers like Kohler, Kawasaki, and Briggs & Stratton depending on the engine model. When you need a replacement, you can use the original Cub Cadet part number, buy the same filter under a different brand name, or choose a compatible aftermarket option — all three will fit and perform the same way.
The cross reference works because filter threads, bypass valve settings, and canister dimensions follow industry standards. A filter made for a Kohler engine that powers a Cub Cadet mower will have the same thread size and flow rate as the Cub Cadet-branded version of that same filter. Knowing this saves you money and time, because you can shop by price and availability instead of being locked into one part number.
Key Takeaways
- Cub Cadet filters are often rebranded versions of Kohler, Kawasaki, or Briggs & Stratton filters, so the same filter may be sold under multiple part numbers.
- You need your engine model number (found on the engine block or in your owner's manual) to find an accurate cross reference.
- Aftermarket filters from brands like Fram, Mobil 1, and Purolator are engineered to the same specifications and will work in your equipment.
- Online cross reference tools from filter manufacturers and Cub Cadet's parts catalog are the most reliable sources for matching part numbers.
- Thread size, bypass valve pressure, and canister height must match — buying the cheapest filter without checking these specs can cause leaks or engine damage.
Where to find your engine model and filter size
Your engine model number is printed on a metal tag or sticker bolted to the engine block. On Cub Cadet mowers and tractors, this tag is usually on the side or back of the engine, below the air filter housing. Write down the entire model number — it typically looks like "SV590" (Kohler) or "FX691V" (Kawasaki) — and keep it with your maintenance records.
Your owner's manual lists the correct filter type and part number for that specific engine. If you no longer have the manual, Cub Cadet's website has a parts catalog searchable by model number of your equipment. Enter your mower or tractor model, and the catalog will show you the engine type and the OEM filter part number. This is your starting point for any cross reference search.
The current filter on your equipment also carries a part number printed on the canister. If the filter is still readable, you can photograph it and search that number directly in cross reference databases. This bypasses the need to identify the engine model and is often the fastest route.
Using manufacturer cross reference tools
Kohler, Kawasaki, and Briggs & Stratton all publish cross reference charts on their websites. These charts list their own filter part numbers alongside compatible filters from competitors. To use them, enter your engine model number or the Cub Cadet part number, and the tool will show you which Kohler, Kawasaki, or Briggs filter will work as a direct swap.
Fram, Mobil 1, Purolator, and other aftermarket filter makers also host cross reference databases. You enter the Cub Cadet part number or your equipment model, and the tool returns the equivalent aftermarket part number. These tools are free and do not require an account. Fram's website, for example, has a "Find Your Filter" search that accepts OEM part numbers and returns Fram equivalents with thread size and bypass pressure listed.
When you find a match, the cross reference tool will show you the thread size (usually 3/4-16 or 3/4-20 for small equipment), the bypass valve opening pressure (typically 3 to 4 PSI for lawn mower engines), and sometimes the canister height. Write these down — they confirm that the filter is truly compatible and not just a similar-looking part.
Common Cub Cadet filter part numbers and their cross references
| Cub Cadet Part Number | Engine Type | Kohler Equivalent | Kawasaki Equivalent | Aftermarket Options |
|---|---|---|---|---|
| 751-10292 | Kohler SV series | 52 050 02-S | N/A | Fram PH8A, Mobil 1 M1-110 |
| 751-10364 | Kawasaki FX series | N/A | 49065-0721 | Fram PH10060, Purolator PL14610 |
| 751-10294 | Kohler CH series | 52 050 02-S | N/A | Fram PH8A, Mobil 1 M1-110 |
| 751-10365 | Kawasaki FR series | N/A | 49065-0721 | Fram PH10060, Purolator PL14610 |
This table shows common matches, but your specific equipment may use a different filter. Always verify the part number on your current filter or in your owner's manual before ordering. Cub Cadet updates part numbers and suppliers periodically, so a filter that worked five years ago may have been replaced with a newer equivalent.
What to check before buying a cross reference filter
Thread size must match exactly. Most small-engine filters use 3/4-inch threads, but the pitch varies — 3/4-16 and 3/4-20 are both common. If you install a filter with the wrong thread pitch, it will either not screw on far enough or cross-thread and leak. Check the old filter or the cross reference tool output to confirm the pitch before you buy.
Bypass valve pressure should be within 0.5 PSI of the original. The bypass valve opens if the filter clogs, allowing unfiltered oil to flow to the engine rather than starving it of oil. If the bypass pressure is too low, it opens too easily and unfiltered dirt reaches the engine. If it is too high, the engine can run dry if the filter clogs. Most lawn mower and small tractor engines use 3 to 4 PSI; check your cross reference tool or manual to confirm.
Canister height and diameter should be similar to the original. A filter that is significantly taller or wider may not fit in the engine compartment or may interfere with the air filter housing. Measure your current filter or check the dimensions listed in the cross reference tool. If the new filter is close in size but slightly different, test-fit it before you install it permanently.
When to use OEM versus aftermarket filters
OEM filters (original equipment manufacturer) are made by Kohler, Kawasaki, or Briggs & Stratton and sold under the Cub Cadet part number. They are engineered specifically for that engine and carry the manufacturer's warranty. If your equipment is still under warranty, using an OEM filter protects your coverage. OEM filters are often more expensive but are may provide to be correct.
Aftermarket filters from Fram, Mobil 1, Purolator, and similar brands are engineered to meet the same SAE (Society of Automotive Engineers) standards as OEM filters. They have the same thread size, bypass pressure, and flow rating. Aftermarket filters are usually cheaper and widely available at auto parts stores and online retailers. They perform as well as OEM filters in normal use, though some owners prefer OEM for peace of mind.
Synthetic media filters (like Mobil 1 M1 series) last longer than conventional paper filters and trap smaller particles. If you change oil more frequently than your manual recommends, a synthetic filter may not be necessary. If you operate in dusty conditions or run the engine hard, a synthetic filter can extend the time between changes. Check the cross reference tool to see which synthetic options are available for your engine.
Where to find cross reference information online
Cub Cadet's official parts catalog (parts.cubcadet.com) allows you to search by equipment model and shows the OEM filter part number and compatible alternatives. This is the most authoritative source and is free to use.
Kohler's cross reference tool (kohlerengines.com) accepts Cub Cadet part numbers and returns Kohler equivalents with full specifications. Kawasaki's site (kawasakiengines.com) and Briggs & Stratton's site (briggsandstratton.com) offer similar tools.
Fram's filter finder (fram.com) and Purolator's cross reference (purolatorfilters.com) let you enter an OEM part number and return aftermarket equivalents. These tools show thread size, bypass pressure, and sometimes customer reviews.
Local Cub Cadet dealers can cross reference a filter over the phone if you give them your equipment model number. This is useful if you need the filter when ready and want to confirm compatibility before you buy.
Frequently Asked Questions
Can I use a filter from a different brand if the thread size matches?
Thread size alone is not enough. The bypass valve pressure and canister dimensions must also match. A filter with the correct threads but wrong bypass pressure can damage your engine. Always use a cross reference tool to confirm all specifications, not just the thread size.
What happens if I install the wrong filter?
If the filter does not screw on, you will know when ready and can remove it without harm. If it screws on but has the wrong bypass pressure, the engine may run unfiltered oil or starve for oil, leading to bearing wear or seizure over time. If it is too large, it may interfere with the air filter or fuel line. Always test-fit a new filter before you tighten it fully.
Do I need to use Cub Cadet brand filters, or can I always use aftermarket?
Aftermarket filters that match the OEM specifications work just as well. If your equipment is under warranty, check the warranty terms — some manufacturers void coverage if you use non-OEM parts, though this is rare for filters. Most owners use aftermarket filters without issues.
How do I know if my current filter is original or aftermarket?
Look at the canister. If it says "Cub Cadet" or the engine manufacturer's name (Kohler, Kawasaki, Briggs & Stratton), it is OEM. If it says Fram, Mobil 1, Purolator, or another brand name, it is aftermarket. The part number printed on the canister will also match the OEM or aftermarket catalog.
Can I cross reference a filter if I do not have the engine model number?
Yes. Photograph the part number on your current filter and search it in a cross reference database. You can also bring the old filter to a Cub Cadet dealer or auto parts store, and they can look up the equivalent. If the filter is too worn to read, you will need the equipment model number to proceed.
