Frequently Asked Questions
What air filters fit a Case 1150B dozer?
Broken Tractor carries the primary Air Filter (SKU R28797) and the Secondary Inner Air Filter (SKU R36360), both of which fit the Case 1150B. For complete engine protection you typically use both the outer primary element and the inner secondary element together. Match the part number to your machine to confirm the correct fit.
What is the difference between the primary and secondary air filter on a Case 1150B?
The primary air filter (SKU R28797) is the main outer element that captures most incoming dust and debris. The secondary or inner air filter (SKU R36360) sits behind the primary and provides backup filtration to protect the engine if the primary is damaged or during service. We carry both for the Case 1150B.
Does the air precleaner assembly fit the Case 1150B?
Yes, the Air Intake Precleaner Assembly with a 5-inch outlet (SKU 258541A1) fits the Case 1150B along with other Case dozer and loader models. It mounts on the intake to remove larger dust and debris before air reaches the primary filter. Confirm the outlet size and part number matches your setup.
What size precleaner bowl fits a Case 1150B dozer?
Broken Tractor offers the Air Precleaner Plastic Bowl with a 12-inch outer diameter (SKU L30671), which fits the Case 1150B and many other Case dozers and loaders. This plastic bowl collects trapped debris from the intake precleaner. Match the SKU to your existing bowl to be sure it is the right one.
How do I know which air filter part number is correct for my Case 1150B?
Fitment on older Case dozers can depend on the exact model and configuration, so the best approach is to match the part number on your current filter to the SKUs we list. If you are unsure, our parts team can help confirm the right filter for your 1150B at (800) 909-7060.
