Oregon Power Mate Rim Sprocket (3/8" x 7 Tooth) Small Spline 18720

ORF 18720
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. This rim has wear depth indicators which tell you when to replace your rim. Small splined rims have a sprocket bore of approximately 3/4". This rim is a .375 x 7 tooth configuration.

Note on MS360: If you have an OEM drum the rim will be either 5/8 (mini) or 7/8" (standard). If you have an Oregon drum, then you are more than likely have a 3/4 (small) or possibly 7/8" (standard). The best bet is to measure to be certain for this particular chainsaw.
