Case IH 1140 Extra Air Filter Notes
| Engine model | Mitsubishi 1.5L |
|---|---|
| Engine displacement | 1.5 L | 91.5 cu in |

| Primary filter note | For the Case IH 1140, the listed primary air filter part number is 222422A1. 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 0455F1. |
| 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: Length: 181 mm | Outside diameter: 124 mm. Use dimensions as a second check, not as the only buying method. |
| Filter size note | The listed dimensions point to a mid-size element length at 7.1 in and normal outside diameter at 4.9 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 | 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 1140 Air Filter FAQs
What is the safest way to match a Case IH 1140 air filter?
Treat 222422A1 as the hero value, not the whole truth. Serial range, engine swaps and different air-cleaner housings can beat a generic online listing.
Is the Case IH 1140 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 0455F1 when you meant the safety filter, or A189348 when you meant the outer filter.
What does the Case IH 1140 horsepower and filter size combo tell me?
Horsepower tells you airflow demand; length and outside diameter tell you rough element size. Together they say whether restriction is a service concern or mostly a fitment check.
How should I use the Case IH 1140 filter dimensions?
The length-to-diameter shape points to a mid-size element. That helps catch obvious bad matches, but part number and seal style should decide the purchase.
What part-number mistake should I avoid on a Case IH 1140?
Multiple numbers are useful only if each one is tied to the correct element position. Wrong element in the right brand is still wrong.
Can a dirty air filter affect Case IH 1140 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 1140 outer and primary filters differ?
Multiple numbers usually means a staged air cleaner. Replace the loaded outer element first, then inspect the safety element without exposing the clean intake to dust.
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.
