Oregon Power Mate Rim Sprocket (.325" x 9 Tooth) Standard Spline 13624
Oregon Power Mate rim sprockets for chainsaws. Rims float on the splined hub of the drum and move side to side, allowing the chain and rim to align with the bar as the chain travels around the bar's groove. The rim gets most of the sprockets wear, and by being replaceable, it extends the overall life and value of the sprocket system. Standard splined rims have a sprocket bore of approximately 7/8". This rim is a .325 x 9 tooth configuration. Replaces the following part numbers:
- Stihl 0000 642 1239
Large splined rims have an interior diameter of approximately 7/8"
