SOCK - LUBE (Komatsu KO4320512)

KO4320512: A worn lube sock can allow contaminants into the lubrication system, leading to accelerated wear on moving components. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO4320512. The lube sock functions as a filter element that traps debris and particles from the lubricant before it circulates. During operation, the sock's material gradually collects sludge and metal fines, which can restrict flow if not replaced. A clogged lube sock may cause insufficient lubrication, resulting in overheating or seizure of bearings and gears. The item ships at approximately 2.3 pounds. Verify the serial number or application, then call (562) 693-7748.
