Deere 6620 - wires behind grain pan over chaffer

Note - two parts - the wires and two holes in the sieve.

My John Deere 6620 needs a little attention in the cleaning section. First the sieve (lower cleaning area) has two holes in it where the metal strips with the notches have broken out. I have pulled the chaffer and sieve out. The wires holding the metal strips that open and close have broke. I can either just get another sieve or weld in the two sections from a junk sieve. Any one ever repaired a sieve and how did you do it?????????

The chaffer (top cleaning area) is in perfect condition and needs no repair. It has probably been replaced.

Next I noticed most of the wire fingers behind the grain pan augers are broken off. The wires (fingers) carry the crop back over the chaffer slightly farther. The fingers also probably let the crop fall onto the chaffer to better blow out chaff and dirt. WHY DO THESE WIRES BREAK OFF ???????? The previous owner had attached thin sheet metal under the wires with stove bolts and washers. The tin under the right and left side is a little longer than in the middle. Is this normal to do??????? IS IT OK TO JUST PUT NEW WIRES IN THE COMBINE and take the tin out??????? Everything else back there seems ok. Is there anything else that works to improve the cleaning area???? Thanks everyone.

When we ran 20 series JD's we took that those wire fingers at the front of the chaffer right out. In a bearded crop they plug up with beards and serve no function other than to make the operating length of the chaffer shorter.

Climbed in the back of the combine this afternoon. The little wire fingers are pretty much broken off behind the grain pan augers. Under the wire fingers is piece of metal that goes from the left side to the right side. It is pretty well beat up as well. Looks like someone shortened it up with a torch to get the crop dropped on the chaffer sooner. Is the piece of metal to be used in all crops??? Maybe the fingers are to be used alone in small grains and the piece of metal added when you are doing corn and beans??? Any advice is appreciated.

If you take the fingers out you will allow trash to drop through when going down hill. You can replace the entire finger bar as an assembly.
