CAP - SEALING (Komatsu KO6735-21-5530)

A worn sealing cap can allow contaminants into the assembly, leading to accelerated wear of internal components. This aftermarket replacement part references the Komatsu catalog and carries the cross-reference number KO6735-21-5530. The cap functions as a protective cover that seals an opening against dirt and moisture. Its plain mechanical role is to block passage of debris while retaining lubricant or pressure within the housing. When the cap fails, the resulting contamination often causes premature failure of bearings or seals. Verify the serial number or application, then call (562) 693-7748.
