All Crop 66 Separator Belt

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello group, just joined. I have an all crop 66 that has a bad separator belt, and I found on another post here what size the belt should be, but we cannot get it to stay on once we put it under load. My first question is should there be a twist in the belt between the Separator drive sheave and the tailings conveyor sheave. The belt we have is 5/8" wide, should it have been 1/2"?
Any help would be appreciated.

BTW, the WD tractor pulling the combine is my Grandpa's he bought new in 1950 and the combine is one a neighbor had that I bought, which was used to combine my families grain when I was a kid. I am still trying to use it as much as possible.
