Hydraulikzylinder am Bagger selber abdichten – Schritt für Schritt Anleitung (Hanix H35A)

In this video, I'll show you how to properly seal, assemble, and reinstall the boom cylinder on a Hanix H35A mini excavator. After disassembling the cylinder in the last video, today we're tackling the heart of the repair: installing the new seal kit! Why it's worth doing it yourself: An original seal kit can cost over €300 (plus tax). I had a kit custom-made by a hydraulic service, halving the cost to approximately €150! 🛠️💰 What you'll learn in this video: ✅ Installation of the sealing sleeves and O-rings (important tips on installation direction!) ✅ Why heat can be risky during disassembly ✅ Installation of the dust deflector and guide bands ✅ Safely assembling and bleeding the cylinder ✅ Functional test on the excavator (leak test) Key chapters in the video: 00:00 Welcome & Cost Check 02:50 The new seal kit: Original vs. aftermarket 05:40 Installing the seals in the nut (tips on the sealing lip) 09:30 Mounting on the piston rod 15:05 Installing the piston seal & guide bands 21:00 Securing the setscrew (center punch mark) 24:30 Inserting the cylinder & connecting the hydraulic lines 33:00 First test run: Is everything leak-free? 42:10 Outlook: Next Project (Felling Trees with a Winch & Chipper) Did you find this video helpful?
