CUP (Komatsu KO44043L0100)

A damaged cup can cause fluid leakage or contamination in a sealed assembly. This aftermarket replacement part references Komatsu as the OE maker and carries the cross-reference number KO44043L0100. The cup functions as a containment component, typically seating against a mating surface to retain lubricant or seal a joint. When the cup deforms or cracks, it may allow debris ingress, accelerating wear on adjacent moving parts. During a routine disassembly, a technician might find the cup flattened or corroded, indicating replacement is needed. The item ships at approximately 0.004 pounds. Verify the serial number or application, then call (562) 693-7748.
