hitachi zx870 sprocket 4430291

When you're operating a 85–90 ton ZX870 in open-pit mining, large-scale quarries, or major earthmoving projects, the sprocket is the part that takes the full brunt of your track chain's power delivery. In the demanding environment of large-scale mining and heavy earthmoving, the Hitachi ZX870 requires a drive system that can translate massive hydraulic power into steady traction. Our sprocket (PN: 4430291 / 4S00649) is the heavy-duty, direct-replacement drive sprocket built specifically for the extreme loads and abrasive conditions that ZX870 owners deal with every day.
