PLUG - DRAIN (Komatsu KO018504)

A damaged drain plug can allow fluid to escape, leading to system starvation and component wear. This aftermarket replacement part references the Komatsu catalog and carries the part number KO018504. The plug seals a threaded opening in a fluid reservoir or housing. Its plain mechanical function is to provide a leak-tight closure that can be removed for fluid changes. A common failure consequence is that a stripped or corroded plug may not seal, causing gradual fluid loss. Keeping a drain plug in sound condition helps prevent contamination from entering the system through the opening. Verify the serial number or application, then call (562) 693-7748.
