Frequently Asked Questions
What filters fit a Case CX370B and CX370C excavator?
Broken Tractor carries air, fuel, and hydraulic breather filters for both the CX370B and CX370C. This includes an outer air filter (KSH0933), an inner air filter (275810A1), fuel filters (MMH80590 and KHH0534), and a hydraulic air breather filter (159702A1). Match the part number to your machine or contact our parts team to confirm fitment.
What is the difference between the outer and inner air filter on a Case CX370?
The outer air element (KSH0933) is the primary filter that traps the bulk of dust before air reaches the engine, while the inner air element (275810A1) serves as a secondary safety filter to catch fine particles that pass the outer element. Both work together to protect the engine from dust ingestion on CX370B and CX370C excavators. We carry both elements.
Which fuel filter do I need for a Case CX370C?
The CX370C uses the fuel filter cartridge with SKU MMH80590. The separate fuel filter KHH0534 fits the CX370B. Confirm your machine model and match the part number, since the two CX370 variants use different fuel filters.
Does the KSH0933 air filter fit other Case excavators?
Yes, the KSH0933 outer air filter fits a range of Case excavators including the CX290B, CX300C, CX330, CX350B, CX350C, CX370B, and CX370C. It cross-references to 73181672 and 87013225. Check the fitment list or verify the part number for your specific machine.
What does the hydraulic air breather filter do on a Case CX370?
The hydraulic air breather filter (159702A1) keeps the hydraulic tank ventilation clean by filtering air that enters the tank as fluid levels change. This prevents contaminants from entering the hydraulic system on CX370B and CX370C machines. Broken Tractor offers this breather filter, which fits a wide span of Case excavator models.
