Frequently Asked Questions
What filters does the Case 921 wheel loader need for routine service?
For scheduled maintenance on a Case 921 loader, Broken Tractor carries primary and secondary engine air filters, an oil filter, a lube combination filter, and a spin-on hydraulic filter. We also offer a cab fresh air filter panel and engine coolant compatible with the 921 series cooling systems. These cover air, oil, hydraulic, and cab filtration for the 921, 921B, and 921C machines.
Do these filters fit the Case 921, 921B, and 921C?
Fitment varies by part across the 921 series, so check each item before ordering. The oil filter (SKU 366700A1), lube combination filter (SKU 3621379M1), and spin-on hydraulic filter (SKU N9086) list the 921, 921B, and 921C. The primary air filter (SKU 627975C3), secondary air filter (SKU 923611C91), and cab fresh air panel (SKU 330014A1) list the 921 and 921B.
What is the difference between the primary and secondary air filter on a Case 921?
The primary air filter (SKU 627975C3) is the main outer element that traps the bulk of incoming dust, while the secondary air filter (SKU 923611C91) is the inner safety element that protects the engine when the primary is removed or damaged. Both are listed for the Case 921 and 921B. We recommend servicing both to keep the intake system sealed.
What is the part number for the Case 921 cab air filter?
The cab fresh air filter panel for the Case 921 is SKU 330014A1, which also fits the 921B. This is the fresh air panel element for the operator cab. If you are unsure it matches your machine, match the part number or confirm fitment with our parts team.
How do I know which hydraulic filter fits my Case 921?
Broken Tractor offers the spin-on hydraulic filter SKU N9086, which lists the Case 921 and 921C. Because filter fitment on the 921 series can depend on the specific model and serial number, match the part number to your machine or confirm with the parts team at (800) 909-7060 before ordering.
