Product Overview
Komatsu identifies this component as a hydraulic-system filter element. Its purpose is to capture damaging contamination before it circulates through pumps, valves, cylinders and motors, where even small particles can accelerate wear or cause sticking.
Komatsu's replacement data shows 21U-60-32121 as the later service replacement for 21U-60-32120. Cross-reference catalogs also list a much broader group of SK, CK and PC compact machines than the original title, which makes the part number the best way to match the element.
