Installation Guide & Best Practices
Step 1: System Preparation
Drain hydraulic fluid completely. Clean all connection points thoroughly. Inspect fittings for damage or wear before installation.
Step 2: Component Installation
Install brackets, grommets, and heat shields first. Route hoses carefully to avoid sharp edges and heat sources.
Step 3: Connection & Torque
Connect fittings hand-tight first. Apply manufacturer torque specifications using proper tools. Avoid over-tightening.
Step 4: Testing & Verification
Fill system with fresh fluid. Start engine and check for leaks. Test steering operation at various RPMs and temperatures.
Maintenance & Longevity Tips
🔍 Regular Inspection
Check monthly for signs of wear, cracking, or leakage. Inspect mounting points and protective sleeves for proper positioning.
🧽 Cleaning Protocol
Clean with degreaser and water. Avoid harsh chemicals that could damage rubber components. Dry thoroughly after washing.
🌡️ Temperature Management
Ensure heat shields are properly positioned. Monitor operating temperatures during extreme weather conditions.
