Oregon Power Mate Rim Sprocket (SD7 Standard 7 Spline) .375" x 8 Tooth. 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 Power Mate rim is radially ported, which helps remove sawdust and debris out from the teeth. This rim also has wear depth indicators which tell you when to replace your rim. Standard splined rims have an inside sprocket bore of approximately 7/8". Rim Specifications: Pitch .375" (3/8"): Teeth 8: Spline Size Standard 7 Spline (SD7)*: Bore 22.25mm (7/8"): Diameter 40mm (1-5/8"). Replaces Stihl part number 0000 642 1216.

Important Note *SD7 Standard 7 Spline Rims have an interior diameter of approximately 7/8" (less the splines) and will only fit clutch drums with that diameter bore. Please check before ordering.
