BREATHER (Komatsu KO3EB-15-11160)

A damaged breather can allow contaminants into a sealed housing, leading to accelerated wear of internal components. This aftermarket replacement part references Komatsu as the OE maker and carries the cross-reference number KO3EB-15-11160. The breather's primary function is to equalize pressure inside a housing while filtering incoming air. A common failure consequence is that a clogged breather may cause pressure buildup, resulting in seal leakage. During routine service, a breather should be inspected for cracks or blockages that compromise its filtering ability. Keeping a breather in sound condition helps prevent moisture and debris from entering the system. Verify the serial number or application, then call (562) 693-7748.
