Cut the chaffer adjusting rod about 8-12 inches from the front of the chaffer, then attach another adjusting lever to this 8-12inch area, seperate from the rest. With this you can open the front of chaffer more than the rest. While in better corn, you'll get more flow to the clean grain auger faster. So, once thats done, then you need to speed up your clean grain auger_elevator. You can do this by changing the size of your sprockets on the driven side of the clean grain auger_elevator or have it driven by the lower fan shaft. I have seen many K's and F's done this way. The K's clean grain auger's driven speed is 316rpm with a 11T sprocket. Its fan shaft speed is 1000rpm - so you need to be careful when using it to drive from. I think your E is very similar to a K with the exception of 2 cleaning fans, but you'll have to compare them yourself. The formula for speeding up or slowing down a shaft is easy. It is directly proportional to the number of teeth on the sprockets involved. Example, the driver shaft on a K is 249rpm at 14teeth and it powers a driven sprocket on the clean grain auger_elevator of 11teeth, so you take 249 x 14 divided by 11 equals 316, the rpm of the clean grain auger_elevator. A hundred rpms increase can increase your capacity tremendously and will not wear bearing, chains, and elevator paddles too much. The faster it goes the faster it will wear!
