JLG Rotary Coupler Seal Kit 70001101

🔹 Product Overview

The Rotary Coupler Seal Kit with JLG Part Number 70001101 is a critical, high-performance seal set designed specifically for the Hydraulic Rotary Coupler (or Swivel Joint) utilized in the turntable assembly of JLG’s large and high-reach Boom Lifts, including the 1250AJP, 1350SJP, 1200SJP, and 340AJ models.1

The rotary coupler is a complex component that enables the continuous 360-degree rotation of the boom and turntable while simultaneously transferring high-pressure hydraulic fluid (for drive, steer, and auxiliary boom functions) and electrical signals to the stationary chassis below.

When the specialized seals within the coupler fail, they cause external hydraulic leaks or internal cross-port leakage (fluid bypassing between circuits). This internal leakage is dangerous, causing sluggish function, intermittent drive/steer failures, and unstable platform operation during rotation. Using the 70001101 seal kit restores the coupler’s integrity, ensuring safe, reliable, and smooth function across all rotational angles.

🔹 Key Features & Benefits

✅ High-Reach Rotary Repair: Specifically designed to rebuild the internal seals of the large Hydraulic Rotary Coupler on JLG Super-Boom Lifts.
✅ Eliminates Cross-Port Leaks: Crucial for maintaining separation and pressure integrity between circuits (drive, steer, auxiliary).
✅ Restores Rotation Reliability: Ensures smooth, predictable hydraulic function regardless of the turntable’s rotational position.
✅ Cost-Effective Solution: Repairs the highly complex and expensive rotary coupler component, providing significant savings over replacement.
✅ Direct Replacement: High-quality aftermarket or genuine OEM equivalent for JLG seal kit 70001101.
