Frequently Asked Questions

What is the difference between the primary and secondary air filter on a Case 921B?

The primary air filter is the main outer element that traps most incoming dirt during engine intake, while the secondary air filter is an inner safety element that protects the engine if the primary is damaged or removed. Broken Tractor carries both for the 921B, including the primary (SKU 627975C3) and secondary air filters (SKU 923611C91 and SKU 1321419A1) for full intake coverage. Replace both to keep the intake system fully protected.

Which air filter fits a Case 921B wheel loader?

We carry an air filter for the Case 921B that replaces 132151A1 (SKU 132151A1), along with primary and secondary elements under SKUs 627975C3, 923611C91, and 1321419A1. Because some 921B air filters also cover the 921C and other machines, match your part number to be sure you get the correct element. If you are unsure, our parts team can confirm fitment for your loader.

Does the cab air filter for the Case 921 also fit the 921B?

Yes, the Cab Fresh Air Filter Panel (SKU 330014A1) fits the Case 621, 621B, 821B, 921, and 921B wheel loaders. This panel handles fresh air cab filtration to keep dust out of the operator area. Confirm the part number matches your machine before ordering.

What oil filter fits a Case 921B wheel loader?

Broken Tractor offers an oil filter (SKU 366700A1) that fits the Case 921, 921B, and 921C, along with a Lube Combination Filter that replaces 3621379M1 (SKU 3621379M1) for engine lubrication service. Both are matched to Case OEM part numbers. Verify the part number against your machine to select the right filter.

What engine coolant is available for the Case 921B?

We carry engine coolant that replaces A77544 (SKU A77544), which fits a wide range of Case machines including the 921, 921B, and 921C. It is intended for cooling system maintenance on your wheel loader. Match the part number to confirm it is right for your application.
