BREATHER (Doosan DWA133182)

A damaged breather can allow contaminants into a sealed housing, leading to accelerated wear of internal components. The Doosan catalog reference DWA133182 identifies this aftermarket replacement part. Its primary function is to equalize pressure while blocking dirt and moisture. A plain mechanical function is the one-way passage of air through a filter element. A concrete generic failure consequence is that a clogged breather can cause pressure buildup, forcing oil past seals. Keeping a breather in sound condition helps prevent premature seal failure and fluid loss. Verify the serial number or application, then call (562) 693-7748.
