DRAIN PLUG (Komatsu KO3EB-41-31221)

KO3EB-41-31221: A damaged drain plug can allow fluid to escape, leading to low lubricant levels and potential component wear. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO3EB-41-31221. The drain plug seals a threaded opening in a fluid reservoir, preventing leaks during normal operation. Its plain mechanical function is to provide a removable seal for periodic fluid changes. A common failure consequence is that a stripped or cracked plug may cause a slow drip, resulting in gradual fluid loss. Keeping a drain plug in sound condition helps maintain proper fluid containment. Verify the serial number or application, then call (562) 693-7748.
