It's STUCK! Can We Get This BIG Cylinder Apart!? | Hitachi ZX470 Cylinder Rebuild | Part 1

This big cylinder rod is stuck and it definitely puts up a fight! This video is Part 1 of rebuilding a stick (dipper arm) cylinder off a Hitachi ZX470 excavator. This cylinder needs rebuilding so we can put it into our exchange fleet but the customer couldn't get it disassembled and the rod is stuck in the barrel. So we use a few different methods including the hydraulic press, the forklift, the big Stillson pipe wrench and even a shipping container to try and get this stuck rod out and the cylinder disassembled!
