The Genie 121310GT Function Pump, 38CC, LS is a genuine OEM hydraulic pump built for the S-80X, S-80, and S-85 telescopic boom lifts. As a direct OEM replacement sourced from Genie, this pump matches the original unit in displacement and load-sensing configuration, ensuring the hydraulic circuit performs exactly as designed. Cross-reference part number 121310GT against your machine's parts manual to confirm it is the correct pump for your serial range before ordering.
Key Features
- Genuine OEM Hydraulic Displacement Match — Built to the original 38CC displacement specification, this pump delivers the correct fluid volume and pressure output the machine's hydraulic circuit requires.
- Load-Sensing (LS) Configuration — The load-sensing design matches the OEM control architecture of the S-80 and S-85 telescopic boom series, preserving proper system responsiveness under varying load conditions.
- Direct OEM Replacement — Engineered to install in place of the original unit with no adaptation, using the same port configuration and mounting interface as the factory-fitted pump.
- Verified Fitment for S-Series Telescopic Booms — Confirmed for the S-80X, S-80, and S-85 telescopic boom lifts; always verify against your parts manual by serial number before installation.
- Operational Integrity — A functioning pump at correct displacement maintains boom extension, lift, and swing response. A worn or failing pump causes sluggish or unresponsive boom movement and should be replaced promptly.
- Safety-Critical Component — The function pump powers the boom's primary movements; an underperforming or failed pump compromises lift and reach capabilities and must be replaced with the correct OEM part to maintain safe aerial operation.
The function pump is the hydraulic pump responsible for powering the machine's working functions — boom lift, extension, swing, and platform leveling — by pressurizing hydraulic fluid and directing it through the control valves to the appropriate actuators. A load-sensing pump, as this unit is, adjusts its output in response to the actual demand of the circuit it serves, providing efficient and controlled movement. When this pump wears or fails, boom functions become slow, erratic, or non-responsive, taking the machine out of service until the pump is replaced.
