Frequently Asked Questions

What filters do I need for a Case 450B dozer?

For the Case 450B, Broken Tractor carries engine air filters, primary and secondary fuel filters, hydraulic and transmission oil filters, and air precleaner assemblies. Because filter specs can vary across production runs, confirm the correct part by matching the part number to your machine or checking your serial number.

Which primary fuel filter fits a Case 450, 450B and 455B?

The Primary Fuel Filter A39868 fits the Case 450, 450B and 455B, and the Secondary Fuel Filter A39867 also covers these models. Both keep the injection system clean, so replace them as a pair for best results.

What is the difference between the primary and secondary fuel filter on a Case 450?

The primary fuel filter (A39868) is the first stage of fuel filtration, while the secondary fuel filter (A39867) provides finer filtration before fuel reaches the injection system. Both are offered for the Case 450, 450B and 455B and work together to protect the fuel system.

Which air filter fits a Case 455B dozer?

Broken Tractor carries air filters R39392 and D82775 (replaces R39393) that fit the Case 455B, along with the Primary Engine Air Filter A42274 for the 188 and 207 diesel engines used in the 450 series. We also offer air precleaner assemblies like A64589 for dusty jobsites. Confirm the right part by matching the part number to your machine.

Does the hydraulic filter fit both the Case 450 and 455B?

Yes, the Hydraulic and Transmission Oil Filter (Spin-On, SKU 84239751) fits the Case 450, 450B and 455B, and hydraulic cartridge filters D75831 and D61950 cover the 450 and 450B. Since fitment can depend on serial number, verify the part number matches your machine before ordering.
