|---|---|
| Engine horsepower | 90 hp | 67.1 kW |
| Primary filter note | For the Case IH 5230, the listed primary air filter part number is 84386403. 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 1265510C1. |
| Safety filter note | The listed inner safety air filter is 381423R92. 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 | Inside diameter: 6 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 | A dirty filter on this setup can show up as reduced pull, black smoke or higher temperature. That is more useful than staring at the hour meter. |
| 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 5230 Air Filter FAQs
Is airflow likely to be sensitive on the Case IH 5230?
If the tractor is under load, a marginal or dirty element will matter more than it does at idle. Use the size/power combo as a reason to inspect before heavy dusty jobs.
How do I avoid mixing up the Case IH 5230 air-filter elements?
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 1265510C1 when you meant the safety filter, or 381423R92 when you meant the outer filter.
How should I verify the Case IH 5230 air filter before fitting it?
If the old filter is missing, use 84386403 plus the housing measurements as a two-step check. If either the seal or cover depth is wrong, do not run it.
Why can a similar-size filter still be wrong for a Case IH 5230?
Length, OD and ID together are better than one size alone. The trap is buying a filter that fits into the canister but does not seal correctly at the ends.
Can a similar Case IH 5230 air-filter number still be wrong?
The part-number pattern can help spot junk listings. If a seller’s number looks nothing like the catalog style, verify it against a real drawing.
What is the biggest fitment trap with the Case IH 5230 air filter?
The trap is assuming a large and deep 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.
Which Case IH 5230 air filter element should I service first?
This is not a one-number job. The outer and inner elements have different jobs, so compare both old parts before buying a kit.
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.
