Frequently Asked Questions

What filters does the Case 1121G wheel loader need?

The Case 1121G uses engine oil, fuel, air intake, hydraulic, and transmission filters as part of routine maintenance. Broken Tractor carries primary and secondary elements along with spin-on and cartridge types for these systems. You can buy individual filters or grouped sets for scheduled service intervals.

Do you sell a complete filter kit for the Case 1121G?

Yes, Broken Tractor offers complete service filter kits for the Case 1121G as well as individual elements. Kits group the filters needed for routine maintenance and overhauls so you can service multiple systems at once. If you only need one element, those are sold individually too.

What is the difference between primary and secondary air filters on the 1121G?

The primary air filter is the main outer element that captures most airborne debris, while the secondary element sits inside as a backup to protect the engine when the primary is being changed. Broken Tractor carries both primary and secondary elements for the Case 1121G. Replacing both during service is a common practice.

How do I know which filter fits my Case 1121G wheel loader?

Match the filter part number to your machine, since fitment can depend on serial number and build configuration on the 1121G. We list New aftermarket and OEM-spec replacement filters matched to the 1121G loader. If you are unsure which element you need, contact our parts team to confirm before ordering.

Are these Case 1121G filters OEM or aftermarket?

Broken Tractor carries both New aftermarket and OEM-spec replacement filters for the Case 1121G. Both are built to fit the engine, fuel, air, hydraulic, and transmission systems on the loader. Check each filter listing to see the exact type offered.
