Seal Kit 7017184 – Optimized Product Page Content

JLG Boom Cylinder Seal Kit 7017184

🔹 Product Overview

The Seal Kit with JLG Part Number 7017184 is a heavy-duty, critical seal set specifically designed for the Primary Hydraulic Cylinder (often the telescope or extension cylinder) used in the largest JLG Telescopic Boom Lifts, including the 1250AJP, 1200SJP, and 1350SJP models.

These large cylinders are subjected to immense hydraulic pressures and loads as they extend and retract the multi-section boom. When the seals within this primary cylinder wear, they cause external fluid leaks (weeping from the end gland) or, more dangerously, internal bypass (fluid leaking past the piston). Internal bypass leads directly to boom sections drifting or retracting unexpectedly, which is a severe safety hazard.

Using the 7017184 seal kit allows for a complete overhaul of the cylinder, restoring its ability to hold pressure under load, eliminating fluid leaks, and ensuring the stability and reliability of the super-boom’s extension function.

🔹 Key Features & Benefits

✅ Super-Boom Cylinder Repair: Specifically formulated kit for rebuilding the primary telescope/extension cylinder on JLG’s large boom lifts.
✅ Heavy-Duty Construction: Seals and wear rings are designed to withstand the extremely high pressures of super-boom extension systems.
✅ Eliminates Boom Drift: Restores internal piston sealing integrity, preventing the extended boom sections from creeping inward.
✅ Cost-Effective Solution: Repairs the existing, highly specialized cylinder, offering substantial savings over a full component replacement.
✅ Direct Replacement: High-quality aftermarket or genuine OEM equivalent for JLG seal kit 7017184.
