The listed dimensions point to a mid-size element length at 7.1 in and normal outside diameter at 4.7 in. Use that as a fitment sanity check against the old filter.

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 Maxxum 140 Air Filter FAQs
What is the safest way to match a Case IH Maxxum 140 air filter?
Do not buy from the title alone. Match 87726675 against the removed filter, then check gasket shape, end-cap depth and cover fit before starting the tractor.
What does the Case IH Maxxum 140 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 do I avoid mixing up the Case IH Maxxum 140 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 87682990 when you meant the safety filter, or 87683000 when you meant the outer filter.
Would I be strict with the Case IH Maxxum 140 air filter condition?
Yes. The power-to-filter-size relationship makes restriction and seal condition worth taking seriously. Replace a questionable element before heavy dusty work.
What size mistake should I watch for on a Case IH Maxxum 140 air filter?
This looks like a mid-size element. Use the dimensions to reject obvious bad cross-references, especially if the inner diameter or seal lip does not match the removed element.
Can the Case IH Maxxum 140 lose power from a dirty air filter?
The important combo is power plus element size. That tells you whether restriction is a real working problem or mainly a fit/seal problem.
Should I buy separate outer and primary filters for a Case IH Maxxum 140?
The presence of both outer and inner numbers means you should order carefully. A kit can be convenient, but only if it contains the correct service element and safety element.
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.
