RING - BACK-UP (Hyster HY1367552)

A damaged back-up ring can allow seal extrusion under pressure, leading to fluid bypass and reduced system efficiency. During disassembly, a retaining ring may become distorted or lose its tension, compromising its ability to hold components in place. The aftermarket replacement part references Hyster as the OE maker and cross-references part number HY1367552. This ring type functions as a mechanical stop that prevents axial movement of assembled parts. A common failure consequence is gradual leakage past the seal, which can accelerate wear on adjacent surfaces. Keeping a back-up ring in sound condition helps maintain proper clearance control within the assembly. Verify the serial number or application, then call (562) 693-7748.
