Frequently Asked Questions

What filters does the Case 621 wheel loader need?

Broken Tractor carries engine air, fuel, oil, hydraulic, and cab air filters for the Case 621 series. This includes primary and secondary engine air elements, secondary fuel filters and fuel/water separators, full-flow engine oil filters, spin-on hydraulic and transmission filters, and cab fresh air filter panels. We cover the 621, 621B, 621B-XT, 621C, and 621D machines.

Which primary air filter fits a Case 621B?

We offer air filter SKU A171838, which fits the 621, 621B, and 621B-XT along with other Case models. For complete engine air protection, it pairs with the secondary inner air filter SKU A47033, which fits the same 621 machines. Match the part number to your unit to confirm the correct fit.

What is the difference between the primary and secondary engine air filter on a Case 621?

The primary air filter (SKU A171838) is the outer element that traps most incoming dust and debris. The secondary or inner air filter (SKU A47033) sits behind it as a backup to catch fine particles that pass the primary and to protect the engine during primary changes. Both are offered for the Case 621 and 621B series.

Does Broken Tractor have a cab air filter for the Case 621?

Yes, we carry the Cab Fresh Air Filter Panel (SKU 330014A1) for enclosed cab units. It fits the Case 621 and 621B wheel loaders. This is a fresh air filter panel, so confirm your machine has the matching cab air setup before ordering.

Which hydraulic filter fits a Case 621C wheel loader?

The spin-on Hydraulic and Transmission Oil Filter (SKU 84239751) fits the 621, 621B, and 621C along with many other Case machines. Because fitment can vary by model and serial number, match the part number to your loader or confirm with our parts team at (800) 909-7060.
