NWP 1/4" Rim & Drum for Echo CS300, 305, 345, 346, 3000-3450 Chainsaws

Convert your standard chainsaw over to a 1/4" pitch carving chainsaw with this drive sprocket system. These are the best drive systems available for your carving chainsaw. The splined drum allows your sprocket to line up with the chain perfectly, and you simply replace your rim when the sprocket wears out. We recommend installing a fresh drive sprocket bearing when changing drive sprockets. Requires a special clutch tool to replace. See related items below.
