Kubota BX24 Oil Filter (Cross-Reference Chart)
For a Kubota BX24, the commonly listed engine-oil filter is Kubota 70000-15241, and WIX 51334 is a commonly cataloged cross-reference. Confirm the tractor’s serial number, engine, and current parts-catalog listing before buying. Aftermarket numbers are candidates, not guaranteed matches. Match the filter’s specifications, install it correctly, and check for leaks before operating.
The BX24 is a compact tractor, but its oil filter is an engine-specific part. A filter listed for another Kubota model may look right and still be wrong for your tractor. The safest approach is to verify the application first, then compare the filter details and follow the operator’s manual for the oil change.
I use the same process when preparing equipment for service: identify the exact machine, check the current parts information, and keep a record of what went on it. That extra step helps when a part number changes or a previous owner has installed a different filter.
BX24 engine-oil filter: what the chart shows
This chart lists common filter references for the BX24’s engine-oil system. It is a starting point, not a substitute for checking the tractor serial number and current manufacturer catalogs. Confirm the part’s application before purchase, especially when ordering an aftermarket filter or using an older parts list.
| Filter listing | How to use it | Important check |
|---|---|---|
| Kubota 70000-15241 | Common OEM reference for the BX24’s D902 diesel engine | Confirm BX24 serial-range fitment and whether Kubota lists a superseding number |
| WIX 51334 | Commonly cataloged aftermarket cross-reference | Confirm current WIX catalog coverage for the BX24 or D902 application |
| Other aftermarket number | Possible alternative only when listed for the exact application | Check the filter maker’s current catalog, not just a retailer’s broad “fits Kubota” label |
A cross-reference is a manufacturer’s statement that one filter may serve the same application as another. It does not mean every filter with a similar shape, thread, or general Kubota fitment is interchangeable. Catalog listings can also change, so check them close to the time you order.
The BX24 uses a Kubota D902 three-cylinder diesel. The filter in this chart is for engine lubricating oil. It is not a hydraulic filter or a transmission filter; those systems use different parts and service procedures.
Key takeaway: Start with Kubota 70000-15241 as a common reference, then verify the current fitment for your tractor before choosing a substitute.
Confirm fitment before buying
Fitment means that a part matches the machine’s intended application and physical requirements. For this tractor, use the serial number and engine identification to confirm the oil-filter listing. Then check for a newer or superseding part number, since a catalog may no longer show the original number as the current service part.
Find the tractor serial number on the machine’s identification plate and confirm the engine information against the operator’s manual or Kubota parts lookup. If the engine or filter application is unclear, ask a Kubota dealer to check the serial range. This matters most on used tractors, where service records may be missing or parts may have been changed.
Before ordering a cross-reference, compare its specifications with the OEM listing:
- Thread: Confirm the thread type and size match. Do not judge it by appearance.
- Gasket seating diameter: The sealing ring must contact the proper flat surface. A gasket that is too large or too small can leak.
- Overall dimensions: Check the filter’s listed dimensions and clearance around nearby parts.
- Bypass and anti-drainback features: Compare the filter maker’s specifications with the OEM application. These internal features may not be visible from outside.
Retailer fitment tools can be useful, but a broad “fits Kubota” result does not prove BX24 fitment. If the retailer and filter-maker catalog disagree, pause and verify with the filter manufacturer or Kubota rather than guessing.
Next step: Save the catalog page or dealer confirmation with your maintenance records. It gives you a reliable reference for the next oil change.
Safe filter replacement, step by step
A safe oil change starts with a stable, cool tractor and the correct parts. Park on level ground, lower the loader and backhoe attachments, set the parking brake, stop the engine, and remove the key. Let the engine cool, wear gloves and eye protection, and have a suitable container ready for used oil.
Follow the oil-drain and refill steps in the operator’s manual for your BX24 serial range. The manual is the authority for drain locations, oil requirements, service interval, and level-check procedure. Do not rely on a generic capacity figure to decide how much oil to pour in.
Use this sequence:
- Prepare the work area. Set out the correct filter, specified engine oil, drain container, and hand tools. Keep dirt away from the oil-fill area and new filter.
- Drain the oil as directed. Allow it to drain into the container. Follow the manual’s directions for plugs and any required handling.
- Remove the old filter. Keep the drain container beneath it. Check the filter’s mounting surface after removal.
- Check the old gasket. Make sure the old filter’s rubber gasket came off with the filter. If it remains stuck to the engine, remove it before fitting the new filter.
- Clean the sealing surface. Wipe away oil and debris without scratching or damaging the surface.
- Prepare and install the new filter. Lightly oil the new gasket with clean engine oil. Fit the filter by hand, following the filter maker’s instructions for tightening. Do not overtighten it with a wrench.
- Refill with the specified oil. Use the diesel-engine oil meeting the operator’s manual requirements, with viscosity suited to the ambient temperature. Filter cross-reference does not determine oil grade.
- Check before returning to work. Start the engine briefly and look for leaks around the filter. Stop the engine, wait and check the oil level using the manual’s procedure. Inspect the filter seal again before operating the tractor.
A doubled gasket is a serious failure risk. If the old gasket stays on the engine and the new filter is installed over it, the joint may lose oil quickly. Do not run the tractor with a leaking seal, an unverified filter, or an unconfirmed oil level.
Common service situations: what to check
These examples describe common decision points during filter service; they are not claims about a specific owner’s repair. The right response depends on what the catalog and inspection show. When fitment is uncertain, pause the job rather than forcing a filter that seems close.
| Situation | What to do | Avoid |
|---|---|---|
| A parts site lists WIX 51334 for “Kubota” | Check the current WIX application catalog for BX24 or the correct D902 application | Assuming a broad brand match proves the part fits |
| The OEM number on an old receipt differs from 70000-15241 | Check the tractor serial number and current Kubota listing for a supersession or prior service part | Treating an old receipt as proof of current fitment |
| The new filter appears similar but has different dimensions | Compare the maker’s dimensions, thread, gasket seating, and internal specifications with the OEM application | Choosing by appearance alone |
| Oil appears around the filter after startup | Stop the engine and inspect the seal, gasket, seating surface, and filter fitment | Continuing to operate while oil is leaking |
In practice, I treat a mismatch in the catalog or at the mounting point as a reason to stop and verify. A filter should thread on correctly by hand and seat as its maker specifies. Never use a wrench to force a questionable part into place.
Oil choice, service interval, and maintenance records
The oil filter and engine oil are separate choices. The filter must match the application; the oil must meet the operator’s manual requirements for the BX24. Use the manual’s viscosity guidance for the expected ambient temperature, and do not select an oil grade based on an aftermarket filter listing.
Service intervals and oil capacity can vary by the applicable manual and service conditions. Follow the operator’s manual for the tractor’s serial range and stated interval. When refilling, use the dipstick and the manual’s checking procedure to confirm the final level rather than relying on a generic capacity quoted online.
Record the service so the next change is easier to verify. Note:
- Date and operating hours
- Filter brand and part number
- Oil brand, type, and viscosity
- Any leaks or unusual findings after startup
Store new filters and oil in clean, dry conditions. Take used oil and filters to an approved collection facility; do not dump oil on the ground or leave oily waste where it can reach soil or water.
Key takeaway: Use the manual for oil type, interval, and level. Use the current parts catalogs for filter fitment.
Frequently asked questions
These short answers address the most common BX24 oil-filter questions. The central rule is to confirm the tractor and engine application using current manufacturer information. If a listing, filter label, or installed part conflicts with that information, verify before proceeding.
What oil filter does a Kubota BX24 use?
Kubota 70000-15241 is a commonly listed engine-oil filter reference for the BX24’s D902 diesel. Confirm the fitment and current part number by tractor serial range.
Is WIX 51334 a cross-reference for the BX24?
WIX 51334 is a commonly cataloged candidate. Use it only when the current WIX application catalog confirms fitment for the BX24 or its correct engine application.
Does every filter listed for a Kubota fit the BX24?
No. Kubota uses different filters across machines and systems. Confirm the exact engine-oil application rather than relying on the brand name alone.
Is the BX24 oil filter also the hydraulic filter?
No. The engine-oil filter serves the engine lubrication system. Hydraulic and transmission filters are separate parts.
How do I confirm the right filter for my tractor?
Check the tractor serial number and engine identification in the Kubota parts catalog or with a dealer. Then confirm the filter maker’s current cross-reference.
Can I choose a filter by its size or appearance?
No. Compare thread, gasket seating diameter, overall dimensions, and bypass and anti-drainback specifications with the confirmed application.
Should I use a wrench to tighten the new filter?
Follow the filter maker’s tightening instructions and install it by hand as directed. Do not overtighten it with a wrench.
What should I do if the oil-filter gasket leaks?
Stop the engine. Check that the old gasket was removed, the new gasket is seated correctly, and the filter is the verified part. Do not operate until the leak is fixed.
What oil should I use with this filter?
Use diesel-engine oil that meets the BX24 operator’s manual requirements. Choose viscosity according to the manual’s guidance for ambient temperature.
How much oil should I add?
Use the manual for the applicable serial range, then verify the final level by dipstick using the manual’s procedure. Do not depend on a generic capacity figure.
