MANIFOLD, TURNTABLE ROTATION 89800 / 89800GT (Slew Valve Block) – Optimized Product Page Content

🔹 Product Overview
The Turntable Rotation Manifold with part numbers 89800 and 89800GT is a highly critical hydraulic valve block designed exclusively to control the Slew (Turntable Rotation) function on compatible Genie Boom Lifts. This manifold manages the precise hydraulic flow to the motor that rotates the turret assembly (the turntable), which is responsible for the machine’s horizontal positioning across a $360^{\circ}$ or continuous rotation range.
This component is absolutely essential for the primary functionality and positioning of the boom lift. The part number 89800GT is the necessary replacement for addressing issues such as slow, erratic, or complete failure of the turret rotation. Because slew movement is required for nearly all boom lift operation, ensuring a fully functional Turntable Rotation Manifold is paramount for efficiency, safety, and operational precision.
🔹 Key Features & Benefits
✅ Slew Control: Precisely manages the hydraulic flow and pressure to the turntable rotation motor.
✅ Full Rotation Control: Ensures smooth, controlled, and accurate 360∘ (or continuous) horizontal positioning.
✅ Essential Boom Function: Direct replacement for resolving hydraulic issues related to turntable rotation failure.
✅ Direct OEM Cross-Reference: High-quality aftermarket equivalent for Genie part numbers 89800GT and 89800.
