I ran out one day to take a look at it, and it looks good, and has fixed the problem for many combines in his area for the last few years. I think it is definitely worth the effort to install, as all the other fix its don't seem to work.
I've followed the directions and modified the parts. Seems to correct some problem areas. When your finished it should turn over by hand real smooth,not binding, so its going to last. Some machines are probably better than others,(mass production). The directions get you an track telling you where to look and check. Satisfied!!!
Heartland Repair posted his phone_fax a while back 701 755 3326 Don't know if he got his web site yet. Think he had a sale on this winter too! All the models come close on the CHAFFER. The long shoe has the worst problem on the rear of the SIEVES And it's real easy to fix! The sieves go back and forth a zillion times a day and just like a wire if you bend it a little a lot it will break.
