Case IH 8940 Extra Air Filter Notes
| Engine displacement | 8.3 L | 504.5 cu in |
|---|---|
| Engine horsepower | 230.8 hp | 172.1 kW |
| Primary filter note | For the Case IH 8940, the listed primary air filter part number is 47610231. Match the number before buying because air cleaner setups can vary by engine, serial range and market. |
| Outer filter note | The listed outer air filter part number is 381423R92. |
| Safety filter note | The listed inner safety air filter is A189348. Do not remove the safety element for normal cleaning; replace it if dirty, damaged or oil-soaked. |
| Fitment note | Listed dimensions: Outside diameter: 9.9 in | Height: 16.4 in. Use dimensions as a second check, not as the only buying method. |
| Filter size note | The listed dimensions point to a long element length at 16.4 in and large outside diameter at 9.9 in. Use that as a fitment sanity check against the old filter. |
| Power range note | Airflow demand rises with load. If the filter is undersized, damaged or badly seated, the engine can lose pull before the element looks completely plugged. |
| Engine airflow note | If a cross-reference is for a different displacement family, verify it hard before buying. Similar model names can hide different intake setups. |
| Service note | Clean loose dust from the air cleaner housing before pulling the filter. Never run the tractor with the filter removed, even for a quick test. |
Case IH 8940 Air Filter FAQs
What is the most reliable way to confirm a Case IH 8940 air filter?
Do not buy from the title alone. Match 47610231 against the removed filter, then check gasket shape, end-cap depth and cover fit before starting the tractor.
Can the Case IH 8940 air filter become a restriction under load?
The combo is a practical warning system. If the element is packed, damaged or not sealing, the engine can lose airflow long before the filter looks catastrophic.
Is the Case IH 8940 air filter a one-part or multi-part service?
For a full parts check, separate the service element from the safety element: buy the outer/primary service element first, then buy the inner safety element only if it is dirty, damaged or due. Do not accidentally order 381423R92 when you meant the safety filter, or A189348 when you meant the outer filter.
How should I use the Case IH 8940 filter dimensions?
A large and deep element should be compared against the removed element before fitting. The danger is a filter that fits loosely enough to bypass dust.
Can a dirty air filter affect Case IH 8940 performance?
Airflow demand rises with load. If the filter is undersized, damaged or badly seated, the engine can lose pull before the element looks completely plugged.
How do the Case IH 8940 outer and primary filters differ?
This is not a one-number job. The outer and inner elements have different jobs, so compare both old parts before buying a kit.
What does the Case IH 8940 air-filter part-number pattern tell me?
The primary number format is a straight numeric OEM-style number, while the page also has separate companion numbers. That is exactly where copy-paste ordering mistakes happen.
Mistakes do happen. Air filter specs can change by year, engine, serial range, market and air cleaner housing. Check the old filter, operator manual, parts book and official caseih.com website before ordering or installing an air filter.
