STIHL Genuine 066, MS660 CrankShaft # 1122 030 0408

Genuine STIHL 066, MS660 crankshaft. It is surely a lovely part it really is one of the the most perfectly machined / finished drop forged parts I have even seen! It is surely a 100% perfectly manufactured precision part and all the tech heads I have spoken to have told me...  all the after market crankshafts are rubbish metal and finish.
If you are repairing one of these popular saws, then you may need this part
