I have an 8010 in Chile, there´s only 4 of these models down here so the dealer knows nothing about solutions; so i need to ask you guys, is there any way to permanently stop the grain getting into the fan chamber ?
Thanks.

If the combine is equipped with long finger pre seive, then you will probably run it closed or next thing to it in small grains. Even if it has grain pre seive you will not want to run it too wide.

we had the problem on a 7010 and had to change the presieve to a small grain sieve and keep it tighter than the manual setting just a little bit more open than the kernel your harvesting. In corn we had to change the clean grain sieve to1 5/8 to make it more aggresive at moving the corn and not letting it go forward on the sieve. We also had to change the pinch point on the rotor as we were overloading the sieves on the right side of the combine.

Good advice above. I have found the 8010 to be very sensitive to fan speed. On the 2388 you could play with the fan speed to get the sample you wanted. Keep slowing it down until it was unacceptable and then speed it up a bit. With the 8010, as you slow it down, by the time you realize it is unacceptable the fan is plugged. Have to run the fan faster than you would be used to on earlier models. Seems to be high air volume with low pressure.

Thanks guys, i´ll be looking for a new pre siege, because i´ve try any possible combination and the plug continuous over and over when going down hill.

Thank you all guys.

I may be different but the few times I've filled my fan up was because I was playing with the bottom sieve adjustment in the cab and closed it too much. The perminent solution is to set the sieves and leave them alone, that's what I did this year with no problems.

What crops do you grow and how's yor growing season doing?

This worked years ago. Put hand full of grain in fan housing.Than with machine running an fan speed slow speed fan up till fan velocity picks up grain an blows it out.Would be curious how close that is to speed you folks run fan speed today.i KNOW that cured 6600jd hilside years ago .Cousin was experiencing same problem. Fan full of corn

So far the harvest season has become sad, we had a shorter spring and the summer came faster so the crop didn´t get enough water.
We are growing winter wheat, spring wheat, spring barley, canola raps and spring oats.

That trick worked with the old paddle style fans like your 6600 deere but not the new style squirrel cage fans like then 8010. New style fans create larger volumes of air with less air velocity and no pulse in the air flow like paddle fan designs have.

I think that this is one of the problems with the combine as setting the bottom sieve too closed should result in too many tailings not a plugged fan. Why pay for the ability to adjust it if you can't for fear of plugging

I think the key word in my statement is "playing". Like I've said before after the first time it's happened...........the second time the pain is self inflected.
