Combines cracking corn HElP

The easiest and actually the ONlY REAl way to solve this problem is to figure out where the cracking is occurring. This is done by doing a kill stall. To do this, simply go combining as you would in the field, and once the machine is full and working as normal, turn the key off (shut the entire combine down while eberything is engaged). Disengage the thresher and restart the engine and let it idle for 5 minutes to adequately cool down the engine and turbo, shut engine off. Then start opening up cleanout doors, concave modules, etc. and find out where the cracking is occurring. Then make the appropriate adjustments to solve this problem. Be patient and be prepared to do a few kill stalls and spend a bit of time before you get it set the way you like it. Spending an hour doing this will pay off in the end.

A loose clean grain elevator can crack corn between the bottom sprocket and the rollar chain. Proper tension is when you can barely slide the chain on the bottom sprocket.

Thanks for the responses, I am going to try pulling out every other wire in the back half of the concave to let the grain out faster...See if that cures it...There is a hammermill like corn powder on the back ledge under the access door to get at bottom sieve, hope that will fix it. let me know what you guys think. Thanks... lA
