BREATHER - DIFFERENTIAL (CAT CT03349-25000)

A damaged differential breather can allow moisture and debris into the axle housing, leading to oil contamination and premature gear wear. This aftermarket replacement part references the CAT catalog and carries the cross-reference number CT03349-25000. The breather's plain mechanical function is to equalize internal pressure as the differential heats and cools during operation. A concrete failure consequence is that a clogged breather may cause seal blowout from pressure buildup. Keeping a differential breather in sound condition helps maintain lubricant integrity over extended service intervals. The item ships at approximately 0.038 pounds. Verify the serial number or application, then call (562) 693-7748.
