O-RING (Komatsu KO30B-63-11440)

A worn retaining ring can allow components to shift, leading to misalignment or leakage. This aftermarket replacement part references Komatsu as the OE maker and cross-references part number KO30B-63-11440. The O-ring type provides a seal between mating surfaces to prevent fluid or gas escape. A plain mechanical function is to compress under assembly to fill gaps. A concrete generic failure consequence is that a hardened or cracked O-ring can cause gradual loss of pressure. The item ships at approximately 0.01 POUNDS.
