Making the Piston & Reassembly! | Hitachi ZX470 Cylinder Rebuild | Part 3

The Hitachi ZX470 Cylinder rebuild is complete! This video is Part 3 of rebuilding a stick (dipper arm) cylinder off a Hitachi ZX470 excavator. In this video we show the complete process of making a new hydraulic cylinder piston including modifying with a silicon bronze weld layer before reassembling the cylinder. We also show pressing in the new bushings with our 150-tonne hydraulic press, installing the new seal kit and painting the rebuilt cylinder. We hope you enjoyed watching the videos on how we complete a hydraulic cylinder rebuild! MISSED PART 1?! Watch it here:    • It's STUCK! Can We Get This BIG Cylinder A...   MISSED PART 2?!
