Running a stripper header in 75+ bushel wheat, im having a heck of a time keeping grain in the machine, and only on the right hand side. Ive added cover plates on thte concave and took some fingers off the distribution augers on the RH side to slow down the flow to the accell rolls. Im about ready to pull my hair out, 4-5mph isnt going to cut it and my capacity is **** since I start throwing grain over the chaffer on the RH side while my loss monitor NEVER goes off on the LH side. Ive got a picture on my phone of the sieve showing the drastic difference between the left and right side of the chaffer, ill post that later if need be.

The Aussies were working on accelerator rolls covers to help with this issue. There is such a dry conditions and low volume the augers are not moving it properly.

My 62 had an extra piece or two under the back auger on the right side that my 76 doesn't have. They just bolted in you might look into that. It should help push it to the center instead of letting it go straight to the acc rolls.

Look at part # 71365773

We put covers on top of the rollers so that they were feed from 12 o'clock rather than 10 o'clock , the main reason being to reduce wear on rollers. Is it an air issue? Blockage on air inlet. I once had similar trouble on an L2 after battling it for a few years I noticed in the manual there was a 3/4" gap just in front and under where the top sieve sits. When I pulled the sieve it was squash on the side I was having trouble . I gave it the correct gap and away it went. I had bent it taking the shoe box out. I don't know what the gap was for as it lead into the dead air area but it had something to do with bleeding air I think.

It seems that its just pouring clean grain out the thresher side, the idea of adding a plate underneath the dist augers seems like it would work. It already has a pan underneath the rear auger, I really wish they would have added it to the front one. It really sucks to have all that cleaning capacity and having a 18" area ruining it.

Heres the chaffer after doing a turnaround with the seperator on letting it clear its throat. This was still laying on the chaffer.

On the sprayer this arvo thinking about it, I remember a guy with a 75 rang me last year with the same issue in canola. He had been through everything and I asked him to check the separator drive pulley on the main shaft for wear as they need to be in good condition. Some months later he saw me and told me that was the problem. He changed the pulley and belt and no more problems. I wonder if the 2012 on S series larger separator drives will fit . I updated my ex 2011 S67 with the kit of 3 pulleys and a belt for $800 us. It would be well worth it.

Any chance that that the tall stripped straw is preventing enough air from entering the fan inlet? Not sure how to check this, but it's something I've always wondered about when running the stripper header. Also, are you generating a large volume of returns, and could this be adding to the right side loading?

 

[shmiffy]

That should be open alot more

 

[mjt]

To have the chaffer shut like that something must be seriously wrong. I would definitly check the seperator drive pulley and belt for wear as it runs fan dist.augers as well,also pulley on main drive RH side for that belt, I have had to replace that due to wear after not many hrs

 

[tbran]

Three things, #1 the chaffer HAS to be at least 1/2" - pref more like 5/8" - no way any Gleaner will be able to run like this on any crop #2 CHECK ACCELERATOR ROLLS - #3 check your fan blades in the cup area for plugging on RH side. Only then add an extension to the trough to move the grain...
The other advice here is worth checking as well...

Ive ran the chaffer in every setting possible, Ive tried opening it up when it first started walking it out the back, I think ive adjusted it at least 25 times. Ive even messed with the shoe a few times but for the most part I leave it set where its at. Through all the settings I can only keep it in the machine when I keep it under 5mph regardless of what setting I have the chaffer on. Just for kicks I ran it up to 8 and 9mph, the left side and middle never even kicked on the sensor even on its most sensitive settings, but the RH side would light it up all the way immediately. After I posted this yesterday I am finding that my distributor augers and return elevator started kickin their respective low speed sensors off under random conditions and when that happened it just loaded the RH side of the chaffer causing me to stop and let its clear its throat while it just tossed grain out the RH side. (it would take 500+ feet for the cleaning system to catch up if I didnt stop) I dont know how I could have so much returns that I slow down the return elevator by having the chaffer as closed as I do. It never kicked on the speed sensors when I had it on the #12 slot and was having alot of returns and producing alot of trash in the bin. I sent a 1.10 dock to the elevator , the average dock as been anywhere from .3 to .7 on average. Ive got 800 acres gone through out of a 1000, the low yields 20-50bushel wheat never bothered my machine, but you start going through 65+ and it starts giving me fits.

Accell rolls are the PFP stainless and poly's they are showing zero wear, the main drive bearings have 200 hours on them. The return elevator belt has 300 hours on it. Ive been very meticulous about maintenance on my machine through the years. Is there a chance the torque limiter is taking a dump on me? If it is has anyone replaced one before, and how much time is involved in that?

 

[ehoff1]

If I remember correctly I run my chaffer at 3/4 of an inch and the sieve at 3/8 with my stripper head. . Does your machine return to cylinder or dump outside cylinder. If outside could you be tailing too much?

What is that rubber curtain below the accelerator rolls above the pan? The one running side to side on the machine at the front of the chaffer? I've never seen that.

Lets see you have a tailings problem which means its going through the chaffer but not the sieve and the into the tailings where it dumps back onto the right hand side of the chaffer and your sample is dirty which indicates a fan problem. Is your fan running fast enough. I had problems with fan sucking corn leaves in and depositing them between the chaffer and sieve. What else could be causing an airflow problem?

 

[WHY NOT]

You don't happen to have reverser bars on the RH side of the rotor causing to much trashing on the RH side of the machine do you?

 

[silverrod]

Did you check that pulley on main shaft. Low speed sensors going off are a good sign of your trouble. It doesn't need much wear to slip.

 

[redline73]

For the short time I ran today, it never set off the low speed sensors. About 15 acres into the day I lost the seal on my rotary screen so I am stopping every 20 mins to sweep off the radiator. I have the seal, but no rivets to put it on. I was willing to put up with that til I jumped the 1st feeder chain completely off the sprockets from one side to the other. This is going not to be a fun job, but after looking at it and sayin some words about agco's complete ineptness in their dealer network I think i can fix it with some #9 wire a come-along and a electric fence post with a j-hook on one end. Course I need another pair of hands to turn the pipe wrench on the splined feederhouse drive, its a perfect learning opportunity for my son. So my previous problem gets to sit on the backburner til i get this all straightened out.

What works for me to jump chain on sprocket is cut length of 1/2 rod little longer than chain is wide, weld piece of threaded bolt on in a T. Bolt onto chain you want to jump and turn over sprocket then take off when you can reach it. Throw T in toolbox.

A bit of rag in there will do the same thing as well

Check your cleaning fan see if it plugged or twisted either will cause what you see in the picture had both happen to me last year

I just got back in the house from getting the chain back on the sprockets. It went pretty easy until the chain got wedged between the bearing housing and the sprocket while walking it on creating a pile of chain that wouldnt walk on the sprocket on the left hand side. It took several hours of persuasion to get it to come loose. Its amazing what you find laying around in old outbuildings that coulda been put there 30+ years ago waiting for this particular purpose.

While I had the top door open to get a look at the feeder chains I got a chance to look at the fan. The slats dont appear twisted and when I opened the door only a small amount of trash fell not enough to plug it up. Now there is alot of straw packed around the area directly in front of the doors., but nothing impeding it from coming in the bottom.
