Genuine stihl crankshaft in excellent condition, no play in the con-rod bearing and main bearings & seals are also good. This has an 8mm wrist pin bearing so its the older design, suitable for stihl 017,018 and early ms170 /180 chainsaws. Please measure your wrist pin first and check its 8mm. Later models are fitted with a 10 mm wrist pin. Any questions please ask
