Stihl Rim & Drum System (3/8" x 7 Tooth) for 024, 026, MS240, MS260 Chainsaws

OEM Rim & Drum from Stihl. This professional drive system includes a splined drum (clutch cup) with a replaceable rim. The rim floats freely on the spline, allowing the saw chain to align with the groove of the bar. The rim is easily replaced once it is worn. Rim & drum sprocket systems do not come with bearings, and we recommend replacing the bearing for every two rim sprocket replacements.
