One of my current projects includes a STIHL ms310. The crankseals are going to be replaced while I have it appart. The problem is that the IPL's show two seals. Both give dementions as a 17mm shaft by 30mm outer diameter by 4.4mm wide. Part #9639-003-1743, and 9639-010-1743. Both seals are listed for the ms290,310 and,390 saws. Not only is the part number different, but price aswell. If anybody, knows the REAL difference please give us your thoughts. Myself and others that came across this would like to know why Stihl went to the effort to list two with no known diff. Please no guess work, we can do that all day ourselves.
