Having a lot of issues trying to get a clean corn sample on my 85 N5, Concave set to 3/4" Air setting is 7. Chaffer opening has been set from 1/2" to 5/8" no difference, bottom sieve quite open, still getting lots of fotter in the bin, loss is low, its like the fan is not working correctly but i can feel the air blast from behind, anything else I can try? oh and its got brand new accelerator rolls.

Need a little more info. Head size,speed, etc. If fodder, what happens when you close the Chaffer? Air is a big deal, is the fan clean?

You haven't been too specific as to how far the bottom sieve is open, ,but you sort of imply that it's open quite a ways. Close it down until you get a clean sample. Darrel

Is there a shield out of place or rusted though? Climb over the shoe and look at the tin in front. 2 years ago we had this issue in our R-62. If its open in front of the shoe trash will fall right on the clean grain auger. Only takes 5 mins to check.

Thanks & God Bless

it sounds like the sieve is open too far. Close it down a little.
Also, make sure ALL shields are in place, including the front one beside the feederhouse. the transverse rotary Gleaner moves a massive amount of air and can suck trash into the fan if all shields are not in place.
Refer to the operators manual for the location of the shields.
