DRAIN PLUG (Komatsu KO3EB-41-12910)

A damaged drain plug can allow fluid to escape, leading to system starvation and potential component failure. This aftermarket replacement part references the Komatsu catalog number KO3EB-41-12910. The drain plug seals a threaded opening in a fluid reservoir, providing a simple mechanical closure. A loose or missing plug may cause gradual fluid loss, resulting in insufficient lubrication or cooling. During routine service, the plug is removed to drain old fluid and then reinstalled. Verify the serial number or application, then call (562) 693-7748. The plug is a straightforward threaded component that requires proper torque to prevent leaks.
