Product Details

- Komatsu
- Warranty
- 6 months
A worn back-up ring can allow seal extrusion under high pressure, leading to fluid leaks and reduced system efficiency. This aftermarket replacement part references the Komatsu catalog and cross-references part number KO45H-405-8240. The back-up ring functions as a rigid support positioned behind a seal to prevent deformation into the clearance gap. Its plain mechanical role is to maintain seal position and resist extrusion forces during operation. A common failure consequence is gradual seal damage and eventual leakage, which can cause pressure loss and contamination. The item ships at approximately 0.066 pounds. Verify the serial number or application, then call (562) 693-7748.
