Rattle Chain

I was trying to pick some corn today with my Gleaner K until the rattle chain slip clutch started slipping. After 2 hours working on it I still couldn't get it to move, usually you can stop the thresher and start it again and it will kick out whatever is hung up but not today. Anyone know a secret to getting everything moving again? This has been happening several times during days I've picked, am I going too fast? I wondered if the slip clutch might not be tight enough??
 
Check for a piece of corn cob stuck under the sprocket aT THE REAR OF THE RADDLE CHAIN. aLSO, ANY BENT RADDLE BARS WILL CARRY A COB AROUND AND JAM at either end. Maker sure the sheet metal curves where it should....
 
Check thru the side access doors first...maybe can turn the shaft back a bit and reach in with small rod to dislodge the cob piece. Cyl breaking up cobs....common for a little chunk to get under the chain, in the sprocket. Sometimes hard to see. Or toss a blanket over the walkers and send a little kid in! Tough going if you have straw rack risers.
 
Do you have wooden or metal slats? Mine always seemed to jamb at the bottom behind the cleanout door. Also, if any slats are missing, the side chains can come together and come off the bottom guides.
 
along with all said good advice,,, my gleaner f had a torn corner on the rattle chain floor front curved section that would catch up ,, raise the head ,, if all you have is the hydro lok switch valve lok and no cylindu channel block , park something like a wagon under headin case the valve or hose fails while you are under there ,,, prepare for a face full once you get theinspection plate off ..mite be able to snip off offending floor pce or rivet some thing back
 
Header lock like this? I made it using a JD cyl as a dummy for the lock to rest on. Never trust a hose!

remove the raddle chain cover under the feeder housing the idlers or the false bottom could be damaged causing it to hang
 
Hey guys, so I went up on Sunday and started the combine, engaged the thresher and it worked great, so yesterday I took it back to the field, got to the exact same spot in the field and it did it again. I removed the front cover and some of the curved metal was torn so I removed it and got back in the cab to try things again and the combine won't start now, just grinds and grinds. Ran fine when I cut it off but won't even fire on ether. Points are brand new so I'm going to try a new coil and see if that is the problem. Its getting gas ok just no spark for some reason.

Also that long chain on the right rear that goes around several sprockets is pretty loose, think it might be binding and causing the clutch to slip?? It was really tight on the gear, I got the chain off the gear and it would turn by hand but before taking the chain off you couldn't move the gear at all.
 
That chain is tight enough if it does not flop around during operation. Your cobs are probably so dry that they are breaking up and being carried around under the raddle like other posters have said. Reduce the cylinder speed and open the concaves til you get whole clean cobs coming out. There should be a torque spec for that raddle slip clutch; mine was tight with about 50 or 60 lbs on the end of a 18 inch johnson bar. If your combine has lots of hours, then the raddle floor has 'bellied' over time and the only solution to that is to remove it and repair or replace--not a fun job BTDT.

90% of the cobs come out whole, the chain was loose enough I could pull it up off the sprocket without loosening anything. It didn't do all of this when I started picking last fall, just started about a month ago, just aggravating more than anything.
