What Is a Kawasaki Oil Filter Cross-Reference (Chart Specs)
A Kawasaki oil filter cross-reference chart matches an original Kawasaki filter number to a replacement filter from another brand. There is no universal Kawasaki filter: identify the engine’s full model and specification code, find its OEM filter number, then verify the replacement’s application and specifications. A shared thread size alone does not prove a filter is compatible.
A cross-reference can look like a simple part-number translation, but it is closer to checking the cast of a movie: the names may differ, while the details determine whether it is the right match. When a manual lists a Kawasaki number and a parts seller lists a different brand, you need to confirm they are approved or cataloged for the same engine application.
I use this order when sorting out a filter match: identify the engine, find its original filter number, check a current catalog, then compare key fit and filtration details. That helps avoid a common mistake: buying a filter because a listing says “fits Kawasaki” or because the threads seem to match.
Confirm the Kawasaki Engine Model and OEM Filter Number
The OEM filter number is the starting point for a dependable cross-reference. OEM means “original equipment manufacturer”; here, it refers to the Kawasaki part number specified for the engine. Find the engine’s full model and specification code first, because the mower or machine brand alone may not identify the engine or its correct filter.
Look for the engine identification label or stamped information on the engine. Record the model and specification code exactly, including letters, numbers, and suffixes. A manual for the equipment may list only the equipment model, so check the engine owner’s manual or a Kawasaki parts lookup for the engine-specific information.
Use that information to find the original Kawasaki filter number. If you cannot locate it, ask a dealer or parts supplier to look it up using the full engine model and specification code. Do not guess based on engine appearance, machine brand, or another engine that seems similar.
Before you search, gather:
- Engine model and specification code
- OEM oil filter part number
- Engine owner’s manual, if available
- Equipment model, as extra context for a parts lookup
This step matters because one equipment maker may use more than one engine, and filter fitment can vary across engines. The engine identification—not a generic “Kawasaki-powered” label—is the useful starting point.
Select and Verify a Compatible Cross-Reference
A cross-reference is a catalog match between an OEM part number and a replacement from another filter maker. Use a current filter manufacturer catalog or a reputable parts lookup, and confirm that it lists your engine application or OEM number. Treat a broad retailer claim as a lead, not final proof.
Example cross-reference
Kawasaki 49065-7007 is commonly cross-referenced to WIX 51358. The 49065-7007 / WIX 51358 application is listed with a 3/4-16 thread. This is one example, not a universal Kawasaki filter match. Check the current WIX application listing and your engine’s OEM part number before buying.
| Check | What to verify | Why it matters |
|---|---|---|
| OEM number | The replacement listing matches the engine’s Kawasaki filter number | Confirms the catalog connection |
| Application | The filter maker lists the specific engine or OEM number | Helps avoid relying on a broad brand claim |
| Thread | Thread type and size match | A mismatch can prevent proper installation |
| Gasket and sealing face | Gasket dimensions and contact area are suitable | The filter must seal against the engine |
| Clearance | The filter fits without hitting nearby parts | A physically obstructed filter may not seat or be serviceable |
| Filtration and bypass | Catalog specifications match the application | Internal design matters, not just outside dimensions |
A bypass valve is an internal valve that can allow oil to flow if the filter media restricts flow under certain conditions. Its specifications, along with filtration characteristics, are part of application fitment. Do not assume that two filters are equivalent because they look alike or share a thread.
If a catalog does not show enough information to confirm a match, contact the filter maker or Kawasaki parts support with the OEM number and engine code. A seller’s “fits Kawasaki” label may cover only some engines or equipment. Get a specific application match before purchasing.
Read a Kawasaki Oil Filter Cross-Reference Chart
A useful chart connects a specific Kawasaki OEM number to a replacement part and gives enough information to verify the match. It should not be read as a list of filters that fit every Kawasaki engine. Check each row against the engine’s exact OEM number and current manufacturer application data.
| Kawasaki OEM filter | Example replacement | Listed thread | How to use the entry |
|---|---|---|---|
| 49065-7007 | WIX 51358 | 3/4-16 | Confirm the engine’s OEM number and check the current WIX application listing before purchase |
The chart above gives one example only. It does not establish that WIX 51358 fits other Kawasaki filter numbers, or that every engine using 49065-7007 has the same service instructions. Use the correct engine manual for oil type, oil capacity, filter-change interval, and installation procedure.
A chart that lists only part numbers may be enough to start a search, but it is not a substitute for checking the catalog’s application notes. If the cross-reference is missing a specification or the listed application does not match your engine, pause and verify instead of filling in the gaps yourself.
Install the Filter and Perform the Oil-Service Check
Correct fitment is only part of the job; the filter must also be installed and checked according to the engine manual. The manual sets the oil grade, capacity, service interval, and installation details, which can vary by engine and operating conditions. If instructions differ from generic advice, follow the manual for your engine.
- Park the equipment on level ground, stop the engine, let it cool, and prevent accidental starting.
- Follow the manual’s oil-draining and filter-removal procedure. Have a suitable container ready for used oil.
- Compare the old and new filters before installation. Check the part number, threads, gasket, sealing face, and clearance. Do not force a filter that does not start or seat correctly.
- Apply a thin film of clean engine oil to the new filter’s gasket, unless the filter or engine instructions say otherwise. Tighten it using the procedure specified by the manual or filter maker. Do not guess at a torque value.
- Refill with the oil grade and amount directed by the engine manual, then check the level as instructed.
- If the manual permits, run the engine briefly. Stop it, inspect the filter area for leaks, and recheck the oil level using the manual’s method.
A filter can screw on yet still have a poor seal or unsuitable internal bypass characteristics. A leak can lower the oil level; an internal mismatch may affect oil flow. If you see a leak, an oil-pressure warning, or hear abnormal engine noise, stop the engine and investigate before using the equipment again.
Practical fitment scenarios
These examples show how to apply the checks; they are not reports of specific customer repairs.
- The seller says “fits Kawasaki,” but gives no engine application. Find the engine code and OEM filter number, then check the replacement maker’s catalog. If the listing remains unclear, ask the maker or parts supplier to confirm the match.
- The new filter has the same thread as the old one. Treat that as one check, not approval. Compare the gasket and sealing face, clearance, and catalog application before installing it.
- The filter number matches, but the filter contacts nearby equipment. Do not force or run it. Verify that the selected part is the correct application and that it has proper clearance.
Maintain Filter Records and Follow the Engine’s Service Schedule
A simple service record helps you repeat a verified match next time. Write down the engine model and specification code, Kawasaki OEM filter number, replacement brand and part number, oil used, and service date or operating hours. Keep the engine manual with the record so you can follow the right interval and procedure.
Follow the interval in the specific engine owner’s manual. The schedule may depend on the engine and how it is used, so do not assume that a general interval for another Kawasaki engine applies. Keep the filter’s packaging or note its number if you may need to verify the purchase later.
Chainsaw fuel mix, chain pitch, chain gauge, bar length, and chain-adjustment settings do not determine oil-filter fitment. Those specifications belong to other parts and systems. For an oil filter, return to the engine code, OEM filter number, and filter-maker application listing.
Frequently Asked Questions
These short answers cover the main checks behind a Kawasaki oil filter cross-reference. The key is to verify the filter against the specific engine and current catalog data, rather than treating a part number, thread size, or brand label as proof by itself.
Is there one oil filter that fits every Kawasaki engine?
No. Kawasaki engines can require different filters. Use the engine model and specification code to find the correct OEM filter number.
What does “cross-reference” mean for an oil filter?
It means a filter maker or catalog lists its replacement filter as matching a specified OEM part or application. Confirm that the listing matches your engine.
Does WIX 51358 fit every Kawasaki engine?
No. It is commonly cross-referenced to Kawasaki 49065-7007. Check the current WIX application listing and your engine’s OEM number before buying.
What is the thread size for Kawasaki 49065-7007 / WIX 51358?
That application is listed with a 3/4-16 thread. The thread information does not confirm compatibility with other Kawasaki filter numbers.
Can I use a filter with the same thread size?
Not on thread size alone. Verify the OEM application, gasket and sealing face, clearance, and filtration or bypass specifications.
Where do I find my engine’s model and specification code?
Check the engine identification label or stamped markings, then use the engine owner’s manual or Kawasaki parts lookup to identify the OEM filter.
Should I choose a filter based on the mower brand?
No. The equipment brand alone may not identify the engine or filter. Use the engine’s model and specification code.
How do I know how much oil to add?
Use the oil grade, capacity, and level-check procedure in the specific engine owner’s manual. Do not assume another engine’s figures apply.
What if the filter leaks after installation?
Stop the engine and address the leak before using the equipment. Recheck the filter application, gasket seating, and installation procedure against the manual.
Do chainsaw chain specifications affect oil-filter fitment?
No. Fuel mix, chain pitch and gauge, bar length, and chain adjustment do not determine which engine oil filter fits.
Bottom line: identify the engine, look up its Kawasaki OEM filter number, and verify the replacement in a current catalog. Then follow that engine’s manual for oil service and installation. A cross-reference is useful only when it matches the specific application.
