I would start modifying the grain diverter.
Combines Side loading on 1660 we ll try this again

Do you have any rubber paddles on the conveyor augersIJ I would start there to get you by till you are close to being done. If you have paddles on the right two augers, you move them around to help distribute the material more to the left. Did you use the quick kill method to determine this problem, or use the loss pattern on the groundIJ

Hey OP, would you mind detailing your quick kill procedure. Since there is some debate about whether this is a good thing to do to your machine ,I am wondering if your success is due to "refining" the system. Can you execute a successfull QK under full load and not pay for it. Thanks, Steve

Ok, believe it or not, I'm not a used car salesman, but I have give a disclaimer up front. Disclaimer: It works for me, but might mot work for you.
I have not done this in corn. I have done it many times in wheat, grass and small seed legumes. Each of these crops use a rotor speed of about 600 to 1000 rpm. On a 1680, that would run in high rotor gear. Example: Combining wheat, 120- 150 bpa. Rotor pull down, 50 -70 rpm from empty speed. Second gear in transmission. I will move my left hand over to the hydro lever, and my right hand on the throttle. While continuing foward motion at the load I run at, in one quick motion I push down on both brakes, pull back on throttle to stop position, and push foward on hydro lever. Do not turn off switches till everything is stopped. Once all still, turn off swithes, pull back hydro and restart engine. let engine cool, then shut off engine. Now you can remove shields and panels to see very closly what the inside of the machine was doing while operating. You can go all the way to the header and look for shatter loss, inside the feederhouse to look for bunching, inside the transition cone to see how it's feeding. And everything else you can think of. You can see on the conveyor auger bed how the material is distributed and if there is a heavy spot, you'll see where it starts. You can check the tailings for content and volume. In corn, you should be able to see the condition of the cobs as they travel to the rear of the cage. Then to restart, again, on my machine, with me operating it, I will put the rotor in low. Sometimes I have to slightly rock it to change gears. Then I will start engine, move throttle to about 1_3, and engage seperator. At the same time the seperator engages, I push throttle to full. let machine clear then engage header. Now having said that, I will say, it may take a couple times to get the hang of it. If you think the machine is almost choked, then put the rotor in neutral and only start the seperator. In fact, if you have a chopper, this may be the way to go. After machine is clear, then put rotor in gear and continue. DONT engage header utill you have the rotor back in gear. In all the years of running, I have never snapped a rotor or seperator belt. I have only worn them out. I do this quick kill every year several times in every crop. This way I dont spend much time guessing where any problems start and what adjustments to make. It has helped me determine where the shortcomings are on the machine and then I can modify accordingly. If you question the abusive nature of this procedure, keep in mind, that when you pull back on the throttle, you are shutting off the full. The engine is simply being shut off at an accelerated rate. If you slug the machine, the throttle is still full on. Just make sure you restart and cool the engine. Upon clearing the machine, in your owners manual, it even says to run throttle to full, then engage seperator. Although I dont do it that way, the factory says you can. Now I probably forgot a few details, so if you have questions, please ask. And if you have more to add to what I do, please post comments. I hope this helps some. It is without any doubt, the most valuable and informative method of diagnosing a problem you can do.

Yes, I have the rubber paddles on the right two augers and they are set for maximum throw. I used the quick kill to double check the ground losses. Thanks for the input.

Jr64, A rotor machine is like an auger screw it dumps the most corn out of one side. Also the tailings dumps on the same side. I would try opening the botom sieve to see if it's coming from tailings. On some machines they have left and right hand bed augers. Just a couple ideas, Good luck.

OldPokey, why do you push forward on the hydrostat IJ I know there's probably a reason. Just curious.

I've not used the brakes, but shut down similar. Have had mixed success on the restart, and usually open the concave to make it easier, then set it back and so have never done one under full capacity.I'm running a 1460 and usually start the threshing mechanism with the engine only at a bit over idle and am not comfortable hitting it too hard.Real good yielding corn may jam the clean grain elevator which is easily fixed by opening the trap door at the bottom.Thanks for the info.

Thats an excellent question. I push on the hydro to help stop the machine in a quicker time. The quicker you can get it stopped, the more accurate the material will be as the machine is in operation. Ohio Steve brings up another good point on the grain elevator. Something I have to learn is some corn is combined at a high moisture content. It could easily clog the elevator. The chopper may also be a concern. However, if you can restart at just above idle, then you should be safe. I agree with you though on not wanting to slam it into gear at a high rpm. Even though it may sound risky to shut down at full capacity, its really the best way to find your problem. If you are not at the load you run at when the problem occurs, it wont quite be as accurate of a diagnoses. It may be close enough though. You just have to get the feel of the quick kill and develope your own restart procedure. Since you already run in low for corn, you may be in better condition than you think for restart. The higher rpm the rotor has to run, the more leverage it has on the engine.

Old Pokey, I have a 2388 and sometimes have trouble getting all of pods and small sticks out depending on variety of soybeans. I was thinking about putting gorton filler plates in. I put 16 spiked rasp bars on back of rotor for beans. Any suggestions IJ Thanks Tim
