I've got 100 acres of beans left to do.
So last night I noticed more trash in the bin than usual. I went to look at the fan setting and it was
low. It wouldn't adjust to above about 750. So needless to say I stopped. It was the throw out type
bearing on the arm that presses on the pulley sheaves that adjust the cleaning fas speed. It was
completely torn out. I put in an new one today and it works like it should. I think.
Here's my question: when I put it together I noticed that the two bolt "ears" that the throw out
bearing run up against are flat spotted pretty good. Were those originally normal Allen head cap
screws that got flattened with friction from the dead bearing? I noticed that I couldn't get the fan to
adjust out until the belt was riding at the top of the split drive pulley - I think it used to. I'm thinking
that those worn bolts are removing just enough adjustment to cause that. I thought about pivoting
them to a new spot and seeing what happened but I thought I would ask here first. It did adjust up
to 1000 which is the highest I run so I am good to cut tomorrow.
The repair bible for the thing does not show any pictures of the adjusting arm up close so I could
figure it out.
