Frequently Asked Questions

What filters do I need to service a Case 550 dozer?

Broken Tractor carries a full set of maintenance filters for the Case 550 crawler dozer, including primary and secondary air filters, an intake precleaner, Cummins engine oil filters, a secondary fuel filter, a fuel/water separator, and a spin-on hydraulic and transmission oil filter. These cover the air, engine, fuel, and hydraulic systems for scheduled service. Match the part number to your machine to confirm the correct fit.

Does the primary air filter and inner air filter both fit the Case 550?

Yes, we carry both a primary air filter (A173290) and a secondary inner air filter (A173291) listed to fit the Case 550, 550E, and 550G. The primary filter captures most incoming debris while the inner filter protects the engine when the primary is being serviced. We also offer the intake precleaner (193867A1) for the same models.

Which engine oil filter fits a Case 550 dozer?

Broken Tractor offers Cummins engine oil filter J908616 and engine oil filter J903224, both listed to fit the Case 550, 550E, 550G, and 550H. Fitment can depend on your engine and serial number, so match the part number to your machine or confirm with our parts team before ordering.

What is the difference between the secondary fuel filter and the fuel/water separator on a Case 550?

The secondary fuel filter (J931063) provides final filtration of the fuel before it reaches the injection system, while the fuel/water separator (J930942) removes water and larger contaminants earlier in the fuel path. Both are listed to fit the Case 550, 550E, 550G, and 550H. Many dozers use both, so replace them together during fuel system service.

Will the spin-on hydraulic filter for backhoes and loaders also fit a Case 550 dozer?

Yes, the spin-on hydraulic and transmission oil filter (84239751) is listed to fit the Case 550, 550D, 550E, 550G, and 550H along with many other Case machines. Because a single filter can cover multiple models, confirm the part number matches your machine. If you are unsure, call our parts team at (800) 909-7060.
