Primary filter note For the Case IH Farmall DX22E, the listed primary air filter part number is PA2539. 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 5046010M1.
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 Listed dimensions: Length: 11.5 in | Outside diameter: 6.5 in | Inside diameter: 3 in. 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 11.5 in and normal outside diameter at 6.5 in. Use that as a fitment sanity check against the old filter.
Power range note With a 22 hp engine class, the listed element size is generous for the power class, so fit/seal checks matter more than chasing a bigger filter. Watch for weak pull, smoke or heat under load before waiting for the full 250-hour guide.
Cross-reference note Possible cross-reference numbers found for the Case IH Farmall DX22E: DX22E. Treat these as secondary checks after the primary filter number.
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 Farmall DX22E Air Filter FAQs

What makes the Case IH Farmall DX22E air-filter number risky to order blindly?

Use PA2539 as the anchor number, then verify the old element and housing label. This is a letter-prefix part number, and the setup looks like primary and outer service-element numbers, with no clean inner safety number shown, so one loose search result is not enough. The size data points to a mid-size element, so compare the removed element against both length and outside diameter before fitting.

Is airflow likely to be sensitive on the Case IH Farmall DX22E?

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.

What should I buy for a full Case IH Farmall DX22E 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 do the Case IH Farmall DX22E air filter dimensions tell me?

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.

When should I reject a Case IH Farmall DX22E cross-reference filter?

Treat the alternate number as a lead beside PA2539. If the gasket, end cap or canister depth differs, walk away.

Why is the exact Case IH Farmall DX22E filter number important?

Use the full PA2539 string. Do not trim suffixes or ignore letters; small part-number changes can mean a different seal or element length.

How do the Case IH Farmall DX22E outer and primary filters differ?

Use the outer number to verify the service element, then look inside the housing for a second filter before closing the job.

Official information note

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.
