|---|---|

| Primary filter note | For the Case IH 4694, the listed primary air filter part number is 381423R92. 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 185168R9. |
| 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: 12 in | Inside diameter: 6 in. Use dimensions as a second check, not as the only buying method. |
| Filter size note | The listed dimensions point to a large outside diameter at 12 in. Use that as a fitment sanity check against the old filter. |
| Power range note | This is a higher-airflow class, so restriction matters fast. If it is working in dust, inspect before the 500-hour planning mark instead of waiting for visible power loss. |
| Engine airflow note | The displacement helps identify the engine family; horsepower tells you how hard it breathes under load. The element still has to match the canister. |
| 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 4694 Air Filter FAQs
What is the safest way to match a Case IH 4694 air filter?
The safest match is not just the printed number. Use 381423R92, then check whether the element seats fully without forcing the cover.
Should I order one filter or a full Case IH 4694 air-filter set?
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 185168R9 when you meant the safety filter, or A189348 when you meant the outer filter.
Which Case IH 4694 air-filter measurement matters most?
One dimension is better than none, but it does not tell you the full canister fit. Check the removed element before installing.
What is the biggest fitment trap with the Case IH 4694 air filter?
The trap is assuming a large outside-diameter element is close enough because it looks right online. The seal face, end-cap depth and cover pressure have to match, otherwise dust can bypass the media.
Why not stretch a dirty Case IH 4694 air filter under load?
This is a higher-airflow class, so restriction matters fast. If it is working in dust, inspect before the 500-hour planning mark instead of waiting for visible power loss.
Is the Case IH 4694 outer filter the same as the primary filter?
The outer filter is the dirt-catcher; the inner filter is the backup. Service them with different expectations instead of replacing both out of habit.
What part-number mistake should I avoid on a Case IH 4694?
The primary number format is a mixed letter-and-number part 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.
