The Genie 9990184GT Internal Retaining Ring is a genuine OEM component built for Genie S-series telescopic boom lifts and Z-series articulating boom lifts, including the S-40, S-45, S-60 J, Z-45/25, Z-45/25J IC Power, Z-45/25 IC, Z-45/25J IC, and Z-51/30J. This #180 internal retaining ring is a sub-component of assembly 139330GT, making correct part identification essential before ordering. As a genuine Genie OEM part, it is manufactured to the same specification as the original, ensuring a proper fit within the assembly it serves.
Key Features
- Genuine OEM Dimensional Conformity — Manufactured to Genie's original #180 specification, this retaining ring meets the precise groove dimensions required for correct seating and retention within the 139330GT assembly.
- Direct Sub-Component Replacement — Designed to replace the retaining ring within assembly 139330GT without requiring modification to surrounding components.
- Broad Boom Lift Compatibility — Fits multiple Genie S-series telescopic and Z-series articulating boom lifts, including S-40, S-45, Z-45/25J, and Z-51/30J models.
- Secure Component Retention — A correctly seated internal retaining ring holds mating components in position within their bore. A worn, sprung, or missing ring can allow axial movement, leading to accelerated wear or assembly failure.
- Assembly Integrity on Aerial Equipment — On boom lifts, retaining components that keep assemblies correctly positioned are critical to safe machine operation. Using the correct OEM ring maintains the integrity of the assembly it belongs to.
An internal retaining ring fits inside a bore or housing groove, where it locks a shaft, pin, or bearing in place axially and prevents unwanted movement along the axis of the bore. When a retaining ring becomes deformed, corroded, or dislodged, the components it holds can shift out of position, causing uneven wear, noise, or loss of function in the assembly. Replacing a damaged ring promptly with the correct part — in this case part number 9990184GT as a sub-component of assembly 139330GT — restores proper retention and extends the service life of the surrounding components. Always cross-reference this part number against your machine's parts manual to confirm it is the correct item for your specific unit and configuration.
