Frequently Asked Questions
It likely does if the parts list for your unit explicitly calls out 100989. Check your model’s manual or exploded diagram to confirm before purchase.
It retains components on a shaft or in a groove so they don’t move under vibration, pressure, or load—maintaining the integrity of the assembly.
Some assemblies specify diameter-matched rings (e.g., around 1-1/8″). Always confirm the ring callout for your assembly to ensure a proper fit.
Use the exact part number shown in your manual. Retaining rings are not universal; different diameters or thicknesses will not interchange safely.
Use the appropriate snap-ring pliers if required, ensure the ring is fully seated in its groove, and verify there’s no burrs or debris that could affect retention.
