RING - BACK UP (Hyster HY154363)

A worn retaining ring can allow assembled components to separate during operation. The back-up ring type serves as a mechanical stop that holds parts in their correct axial position. When this ring fails, the resulting loss of preload may cause shaft or bore components to shift unexpectedly. This aftermarket replacement part references the Hyster catalog number HY154363. The ring is a simple, non-sealing component that relies on its cross-section to resist deformation under load. A common failure consequence is gradual disengagement of the retained assembly, leading to noise or vibration. Verify the serial number or application, then call (562) 693-7748.
