Fitment note
Listed dimensions: Length: 12 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 12 in and normal outside diameter at 6.5 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 CS 52 Air Filter FAQs
Why should I compare the old Case IH CS 52 filter before buying?
The buying order should be: old filter number first, housing fit second, then cross-reference. Start with 877-1000, but do not ignore the a primary, outer and inner safety element setup. The size data points to a mid-size element, so compare the removed element against both length and outside diameter before fitting.
What should I buy for a full Case IH CS 52 air-filter service?
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 381423R92 when you meant the safety filter, or AF1632 when you meant the outer filter.
Does the Case IH CS 52 filter size look right for its horsepower?
The useful read is not the raw size by itself. Compared with the 52 hp engine class, the listed element size is generous for the power class, so fit/seal checks matter more than chasing a bigger filter. Use that to decide how cautious to be in dusty work.
Why can a similar-size filter still be wrong for a Case IH CS 52?
The useful thing is the relationship between the three measurements: length checks housing depth, outside diameter checks the outer seal, and inside diameter checks the center opening. A filter can match two and still fail the third.
How do I avoid mixing up Case IH CS 52 outer and safety filters?
This looks like a multi-element setup. Keep the outer/primary service element and the inner safety element separate when ordering, because mixing up 381423R92 and AF1632 is the easy mistake.
When does the Case IH CS 52 air filter become a performance problem?
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.
Why does the full Case IH CS 52 air-filter number matter?
Multiple numbers are useful only if each one is tied to the correct element position. Wrong element in the right brand is still wrong.
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.
