Description
Overview:
The Rim Sprocket 325-9 SD7 for Chainsaws is a Genuine Oregon Part (13624) designed to drive .325 inch (8.26 mm) pitch chains with a 9-tooth profile. Built from durable steel, it forms a key part of the clutch drum drive system, helping to deliver smooth, consistent chain motion under load. The SD7 spline suits compatible 7-spline clutch drums, making it a practical replacement for many mid-size petrol chainsaws used by professionals and DIY users. Its radial port design helps clear sawdust and chips from the drive area, while wear-depth indicators show when the rim is due for replacement. Choose this genuine component to maintain cutting efficiency, reduce unnecessary wear on the chain and bar, and keep your saw performing reliably.
