The Genie 81386GT Drive & Function Pump Assembly is a genuine OEM component built for Genie S-80 and S-85 telescopic boom lifts. As a direct OEM replacement, this assembly is sourced to the same standards as the original unit installed at the factory, ensuring it integrates correctly with the machine's existing plumbing, mounting, and controls. Cross-reference part number 81386GT against your machine's parts manual to confirm this is the correct assembly for your serial range before ordering.
Key Features
- Genuine OEM Construction — Built to the same specification as the original assembly, with matched porting, correct displacement, and dimensional conformity that aftermarket substitutes may not replicate.
- Combined Drive and Function Output — Integrates both drive and function circuits in a single assembly, simplifying installation and restoring full machine capability in one service operation.
- Direct-Replacement Fit — Engineered to mount and connect exactly as the original unit, working with the factory plumbing and control interfaces on S-80 and S-85 booms without adaptation.
- Confirmed S-80 and S-85 Fitment — Validated for Genie S-80 and S-85 telescopic boom lifts; always verify the part number against your serial number in the Genie parts manual.
- Restores Full Machine Performance — A worn or failing pump assembly causes sluggish drive response, weak or erratic boom function, and ultimately machine shutdown; replacing it with the correct OEM assembly brings performance back to specification.
- Operational Safety — On an aerial boom lift, consistent and responsive drive and function output is essential for controlled operation at height; an OEM assembly maintains the performance margins the machine was designed around.
The Drive & Function Pump Assembly supplies pressurized fluid to both the drive system and the boom function circuits on the machine, allowing the operator to travel the unit and operate the boom simultaneously or in sequence. When the assembly wears or fails, symptoms typically include reduced drive speed, slow or unresponsive boom movement, excessive noise from the pump, and fluid loss — all of which ground the machine until the assembly is replaced. Installing the correct OEM assembly on your S-80 or S-85 restores the full range of drive and boom functions the lift was built to deliver.
