      Hi- I have a 1969 Chrysler 3.5 hp air cooled engine that is like the West Bend Style.  Model # 313 and serial 107*.  I am looking for part numbers for the driveshaft seals (I believe they are identical placed back to back ) and also the prop shaft seal. OR if anyone knows where I can purchase new seals. I do not see any numbers stamped into the seals.  Thanks, Gary

        If all else fails, you can try to find some that fit per size needed.

          Thanks Buccaneer.  I did use a mic on the shafts and tried to measure the outside diameter of seal by trying to mic the hole they go into. Can’t get accurate reading unless I pull seals out. Was hoping to see if I could buy seals before having to pull old ones out and destroying them.

            I removed the seals to try and mic the outer seal dimension. They have a retaining washer that holds in just a rubber seal. There is no metal outside to the seals that gets tapped in. I downloaded a parts diagram book for this motor and I was able to get part numbers of the original seals and find new ones on the internet. Thanks for the help.
