Case IH DX35 Extra Air Filter Notes

Engine model Shibaura 1.7L
Engine displacement 1.7 L | 103.7 cu in
Engine horsepower 35 hp | 26.1 kW
Primary filter note For the Case IH DX35, the listed primary air filter part number is 1265510C1. 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 86401594.
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: 10.8 in | Outside diameter: 4.1 in | Inside diameter: 2.2 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 10.8 in and normal outside diameter at 4.1 in. Use that as a fitment sanity check against the old filter.
Power range note Use the power class to decide urgency. Higher airflow demand means less patience for questionable media, bad seals or packed pleats.
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.
Cross-reference note Possible cross-reference numbers found for the Case IH DX35: 86519866, 87300178. 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 DX35 Air Filter FAQs

Can the Case IH DX35 air filter become a restriction under load?

The combo is a practical warning system. If the element is packed, damaged or not sealing, the engine can lose airflow long before the filter looks catastrophic.

What should I check before ordering a Case IH DX35 air filter?

Because this listing shows primary and outer service-element numbers, with no clean inner safety number shown, the risk is ordering one correct number and one wrong companion element. Keep 1265510C1 as the main reference, then confirm the other elements separately.

How do I avoid mixing up the Case IH DX35 air-filter elements?

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.

Should I trust Case IH DX35 air-filter dimensions or the part number?

This looks like a long, narrow element. Use the dimensions to reject obvious bad cross-references, especially if the inner diameter or seal lip does not match the removed element.

What is the biggest fitment trap with the Case IH DX35 air filter?

The trap is assuming a long, narrow 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.

Can I use aftermarket cross-reference filters on a Case IH DX35?

Use the two cross-refs as alternate leads. If either one disagrees with 1265510C1 or the physical dimensions, ignore it.

Can I ignore letters or suffixes in the Case IH DX35 filter number?

Part numbers are not keywords to approximate. One missing suffix can send you to a related filter that does not seal correctly.

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.
