Frequently Asked Questions

What air filters fit a Case 1450B dozer?

Broken Tractor carries both primary and secondary engine air filters for the 1450B. The primary air filter is available under SKU S231996 or A43656, and the secondary air filter is SKU K0850561. Match the part number to your machine or confirm with our parts team before ordering.

Does the 1450B and 1455B use a primary and secondary air filter?

Yes, both the Case 1450B and 1455B use a primary engine air filter and a separate secondary (inner) air filter. We offer primary elements S231996 and A43656 along with the secondary element K0850561. Replacing both together during service helps keep the engine air intake protected.

What hydraulic filter fits a Case 1455B dozer?

We carry a spin-on hydraulic filter, SKU N9086, that fits the Case 1450B and 1455B hydraulic circuit. This single spin-on serves the hydraulic system on these crawler dozers. Confirm the part number matches your machine before ordering.

Do you have the precleaner bowl and assembly for a Case 1450B?

Yes, Broken Tractor offers the air intake precleaner assembly with a 5 inch outlet, SKU 258541A1, and a replacement 12 inch OD plastic precleaner bowl, SKU L30671. Both fit the Case 1450B and 1455B dozers. Order the bowl on its own if only the plastic bowl is cracked or missing.

Are these filters verified to fit both the 1450B and 1455B?

Yes, the air filters, precleaner parts, and hydraulic filter we list all carry fitment for the Case 1450B and 1455B crawler dozers. Because some parts also serve other Case machines, match the SKU to your equipment. If you are unsure, call our parts team at (800) 909-7060 to confirm.
