CNH Industrial 84339375 Breather Valve

The 84339375 breather valve is an original equipment component designed for CNH Industrial engine crankcase ventilation systems. It regulates internal crankcase pressure, preventing oil leaks and seal damage while blocking external contaminants from entering the engine. This part serves as a direct replacement for legacy part numbers R24861 and R42714. It is engineered for compatibility with New Holland D-series crawler dozers and Case IH 650, 750, 850, and 855 series tractors, as well as 1150MLT, 1650MXLTBD, and 2050MLT dozers. The valve assembly ensures reliable operation in heavy-duty construction and agricultural environments.
