The Genie 58489GT is a genuine OEM Auxiliary Power Unit 89617GT Pump Assembly built for Genie S and SX series telescopic boom lifts and Z series articulating boom lifts. As a direct OEM replacement, this assembly is manufactured to the same specifications as the original unit installed at the factory, ensuring a correct fit and proper operation across all compatible machines. Compatible models include S-40, S-45, S-60, S-65, S-80, and S-85 variants, SX-135 XC, SX-150, and SX-180 telescopic booms, and Z-60/34, Z-62/40, Z-135/70, and ZX-135/70 articulating booms. Cross-reference part number 58489GT and the referenced assembly number 89617GT against your machine's parts manual before ordering to confirm this is the correct unit for your specific model and configuration.
Key Features
- Genuine OEM Construction — Manufactured by Genie to original specifications, delivering dimensional conformity and material grade that match the factory-installed unit for assembly 89617GT.
- Direct OEM Replacement — Designed to install in place of the original pump assembly without alteration, maintaining correct mounting, porting, and drive interface for the machines listed.
- Broad Boom Lift Compatibility — Fits a wide range of Genie S, SX, and Z series boom lifts, including XC, TRAX, HF, HC, J, and other variants across the telescopic and articulating families.
- Auxiliary Power Availability — A functioning auxiliary power unit keeps emergency lowering and secondary machine functions operational when primary power is unavailable; a failed pump assembly can leave the machine unable to respond to critical commands.
- Operational Safety Assurance — The auxiliary power unit is integral to safe machine recovery and controlled descent; using a genuine OEM assembly helps ensure the system responds as intended when it is needed most.
The auxiliary power unit pump assembly provides a secondary source of powered function for the boom lift, allowing the machine to be operated or recovered when the primary drive system is not available. On aerial boom lifts, this capability is essential for controlled lowering of the platform in the event of a primary power loss, protecting operators and equipment. When the pump assembly fails or degrades, auxiliary functions may become sluggish, unresponsive, or entirely unavailable, making prompt replacement with a correct OEM part the right course of action.
