SERVICE NOTE: In late 2013, Stihl changed the design of the TS410 and TS420 crankcase, which also changed the size of the flywheel side bearing. This crankshaft assembly includes both the early model and later model crankshaft bearing sets. No matter the model year of your saw, you'll be able to make the repair using the correct parts. Make sure to measure both bearings to determine if you need the 36.3mm or 35mm O.D. bearing on the flywheel side. Not compatible with greater than 10% ethanol fuel.
