O-RING (Hyster HY18973)

A damaged retaining ring can cause component separation under load or vibration. This aftermarket replacement part references Hyster as the OE maker and carries the cross-referenced part number HY18973. A retaining ring functions as a fastening element that holds assemblies in position within a bore or on a shaft. One plain mechanical detail is that it resists axial displacement without requiring threads or additional hardware. A realistic consequence of failure is that a missing or fatigued ring may allow a driven gear to walk out of alignment. The item ships at approximately 0.032 POUNDS. Verify the serial number or application, then call (562) 693-7748.
