6600 combine issues

Looking for some answers on a 6600. Started shelling corn today, been a very late and wet fall in the finger lakes and moisture today was 28%, and underneath my feet in the feederhouse and as soon as corn would start entering would come a loud banging noise that was not consistent time wise. In other words it would bang at random but pretty often. I realized that I did not adjust the drum with the little setup at the bottom of the feeder house and was gonna do that first thing tomorrow morning. But am,also curious if there might be more to the issue than that. If anyone has any ideas I would appreciate hearing them. What puzzles me a little is its only when corn is going through. Harvested 100 acres if do ya with it recently and it never banged or made any noise.
 
Is the feeder house chain tight? Are all the chain links intact? No broken bolts relative to the cylinder? Nothing loose or out of place with the beater? I've got a piece of sheet metal with a small tear where the beater runs but for the time required and with the little trouble posed at present it is going to wait until the end of the season if possible. I already lost a harvest day changing out a straw walker this fall.
 

Looks like some previous owner went and lost the operator’s manual. The good news is that the price is right for a new one at 1-800-522-7448. Lots of vital setup info in there . The location of hidden grease zerks too. Don’t blow the seals out of the bearings .
 
Corn will be more "bangy" than beans going through the combine. My first guess would be to check the stone trap, but it sounds like you already did that. Had one poster below ever read a combine operator's
manual, he'd know that "random banging" is not covered in either the index or the troubleshooting system of the manual.

In other words, you did the right thing by asking advice.

I'd look over the cylinder closely, as well as the drive belts. You might also look at the steel pieces that close off the connection of the cylinder to feederhouse, and make sure nothing is loose.

I had a strange noise the other night on the 9500... there was good "whump" side of the cab by the door. I stooped and looked, and saw nothing. I thought after inspection that perhaps an ear flew out and
hit side of the cab. The next morning, the same thing. And then it happened, a couple whumps and the head stopped. The outside skin of the feeder house drive belt had been coming off, and finally
separated! The noise was bits of belt hitting the shield. That one wasn't covered in the manual, either.

Where are you in the Finger Lakes???
 
Ya I have a manual for it and you're 100% right, random bangs are not covered in the manuals lol. And yes I will check cylinder and around it thoroughly tomorrow morning with more light. The only thing I keep thinking is if it was the cylinder or something around it I would think it would bang all the time vs just when corn is in feeder house. But i could be wrong, wouldn't be the first or last time. Thanks for advice. And I live 5 miles from canandaigua lake
 
have you changed the drive sprocket for the feeder house chain. you need to be in the fast setting. some banging is common in corn

Hey no I have not, will look into it thanks
 
I've only harvested corn once in my life and that was with our 3300 and 343. It did some banging. Didn't know if that was normal or not either.
 
My experience is corn is alot noisier
than soybeans. The noisier the better.
I have some spots where the soil is
rather poor quality and in a bad year
the combine will go quiet.
 
Check the Feeder house drum for being level, does it protrude as far forward as the other side, is the chain even on the sprockets and the chain not jumped a tooth .The lower stops will get stalks and dirt build up which holds the drum up on one side. The upper shaft could have the bearing outside and inside ,its hidden but the shaft wont be straight . Then last the easy part , does it have the false bottom in there , if not corn flying around will get an ear under the chain and make a BANG because the front drum raises up then drops . Every fix with the exception of the front drum means the feeder house must be removed from the machine . I worked on these combines since they first came out .
 
Thanks for all the advice everyone. I
figured it out. I pulled off The two
plates, above the cover that flips open so
you can view the feeder house, and found
that the top one closest to the cylinder
has a thin guard bolted to it that is
supposed to block any corn from coming back
around into the feeder house. It was broke
in a spot and allowing the ears to come
back over top and drive into that second
plate. It had actually cracked that second
plate as well. Again thanks for all the
advice and happy harvesting to everyone!
 
When ever you have ears wanting to come back down the feeder house it usually means the rasp bars are dull and smacking the ears away instead of sucking them under the cylinder..
