Hitachi EX120-2, EX120-5, EX120-6, ZX135 Arm / Stick Cylinder Assembly – Complete Replacement Unit

Get your Hitachi EX120-2, EX120-5, EX120-6, ZX135 reaching and crowding with full force again with this complete arm cylinder assembly. Built to match the original OEM dimensions, it comes complete with barrel, rod, piston, gland and seals already fitted. Cross-references OEM part number 4364913.

Internal bypass in an arm cylinder robs you of digging force and makes fine grading difficult — and a scored or bent rod will only keep destroying seals. Rather than losing days to a rebuild, swap in a complete new assembly and get the machine straight back to work. At this size the machine is usually earning on a contract, so a leaking or weak cylinder is a direct hit to productivity.
