Case IH 7150 Extra Air Filter Notes
| Engine displacement | 8.3 L | 506.5 cu in |
|---|---|
| Engine horsepower | 241 hp | 179.7 kW |
| Primary filter note | For the Case IH 7150, 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 | If your air cleaner has an inner safety element, leave it in place while servicing the outer filter so dirt cannot fall into the intake. |
| Fitment note | Check the old filter, air cleaner housing label and parts book before ordering if the tractor has had an engine or intake-housing change. |
| 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 | A similar horsepower rating does not guarantee the same filter if displacement or engine family changes. Use the engine data as a sanity check only. |
| 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 7150 Air Filter FAQs
What should I buy for a full Case IH 7150 air-filter service?
Because no clean inner safety number is shown, treat the visible outer/primary numbers as the main service parts and inspect the housing before assuming there is no safety element.
What would make a Case IH 7150 air filter cross-listing suspicious?
The safest match is not just the printed number. Use 381423R92, then check whether the element seats fully without forcing the cover.
Can a dirty air filter affect Case IH 7150 performance?
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.
How do I avoid mixing up Case IH 7150 outer and safety filters?
The outer element is the one most likely to be dirty. If there is a smaller element behind it, leave that one protected unless it needs replacement.
How should I read the Case IH 7150 air-filter number?
A clean part number is more useful than a generic model-name listing. Model-name compatibility tables are often the weak link.
Can displacement catch wrong Case IH 7150 filter listings?
A similar horsepower rating does not guarantee the same filter if displacement or engine family changes. Use the engine data as a sanity check only.
Is the Case IH 7150 inner filter a normal service part?
If the tractor works in dust, confirming whether a safety element exists is worth the extra minute. Dirt past the primary filter is how engines get expensive.
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.
