Hopefully this is in the right section. I finally started to get my sickle on my 100. I went to turn it over after I got it hung under there and noticed the crankshaft shaft turned a 1/4 turn before anything moved. So had to tear it apart. Figured the pins went through both shafts. Welded a nut on the pin to get some leverage to pull it out. Got that out then drove the shaft out. Had to get the small piece out by drilling it out. Now I just need to find a solid 1/4"x3" friction fit pin to put it back together.
