The Genie 139339GT is a genuine OEM Piston Pump Control Kit built for Z-135/70 and ZX-135/70 articulating boom lifts. Sourced directly from Genie, this kit delivers the exact components needed to restore proper pump control function on these large-platform articulating booms. As a genuine OEM part, it meets the same standards as the original hardware installed at the factory, ensuring a correct, direct-replacement fit for the machines listed.
Key Features
- Genuine OEM Components — Each piece in the kit is manufactured to Genie's original specifications, including dimensional tolerances and material grades critical to pump control performance.
- Complete Kit Format — Supplies all necessary components for the pump control service in one part number, so technicians have everything on hand before starting the repair.
- Direct Replacement Fit — Engineered specifically for the Z-135/70 and ZX-135/70 articulating boom lifts, this kit installs without modification or adaptation to the existing pump assembly.
- Restored Pump Control Response — A worn or damaged pump control assembly can lead to erratic or unresponsive boom movement. This kit brings the control circuit back to proper operating condition, supporting smooth, predictable motion.
- Operational Safety — On large articulating booms operating at height, precise pump control is directly tied to safe machine movement. Using the correct OEM kit helps ensure the hydraulic control system behaves as designed.
The pump control assembly on a piston-type pump regulates the flow and pressure output delivered to the machine's hydraulic circuit, governing how smoothly and accurately the boom responds to operator commands. On high-reach articulating booms like the Z-135/70 and ZX-135/70, degraded pump control can result in sluggish, jerky, or inconsistent boom movement — conditions that affect both productivity and safe operation at elevation. Replacing worn pump control components with this genuine OEM kit restores the system to its designed operating parameters and helps maintain the performance these machines depend on.
