Frequently Asked Questions

What air filter fits a Case 21F wheel loader?

Broken Tractor carries the Case secondary (inner) engine air filter, SKU 222429A1, for the 21F and related Case loader models. It is the inner element that protects the engine intake from fine dust that bypasses the primary filter. Always verify by part number and model before ordering.

What is the secondary inner air filter for on a Case 21F?

The secondary inner air filter guards the engine intake against fine particulates that get past the primary element. It gives an added layer of engine protection when dust conditions are heavy. On the Case 21F it works alongside the primary filter for reliable airflow and protection.

When should I replace the secondary air filter on a Case 21F wheel loader?

Replace the secondary inner element at the recommended service intervals or when you change the primary filter. Changing both together helps keep dust from reaching the engine. Follow your machine's service schedule for the correct timing.

Does the Case 222429A1 air filter fit other Case models besides the 21F?

Yes, the 222429A1 secondary air filter also fits the 21D and 221D loader models among others. Because fitment can vary by model and serial number, match the part number and confirm with the parts team before ordering. You can call (800) 909-7060 for help confirming fitment.
