FILTER - OIL (Komatsu KO4390593-4-ALT)

KO4390593-4-ALT: A degraded oil filter can allow contaminants to circulate, accelerating wear on moving components. This aftermarket replacement references the Komatsu catalog and cross-references part number KO4390593-4-ALT. The filter traps particles and debris from the lubricating oil to protect internal surfaces. Over time, a clogged filter may restrict oil flow, leading to insufficient lubrication and potential overheating. During routine service, checking the filter condition helps avoid premature component failure. The item ships at approximately 1.2 pounds.
