There is a curved piece that goes to right above the radiator to get air. Take out the five bolts, loosen the hose clamp and just turn it and point it up.

It works great and all you have to do is loosen the clamp and put it down to go down the road.

Now this is just a field mod so it is not the best, we plan on putting a piece of screen over the end so that the corn leaves don't fly in.

As you can see it's up above the dirt.




And it looks kind of goofy but who cares

Re: early sts owners-fast and cheap way to fix int

Do you have trouble with you intake, or why do you have to move it?

I guess what I am asking is why should I do it to mine.

Re: early sts owners-fast and cheap way to fix int

Mabey you don't have trouble like we do. We clean the filter out every morning and not just clean it, we get most of the dirt out since we have a compressor that we pull behind the shoptruck powered with a 3 cylinder Deere diesel. And from 1 p.m. on the filter has to be cleaned out every two hours because of the dust. And now we don't have to do that anymore.

We can't be the only ones with this problem? davedan where are you?

Re: early sts owners-fast and cheap way to fix int

I see. I don't think we harvest in as dirty as conditions as you. We harvest around 2000 acres of wheat each year with a little milo in the fall. I usually either blow or wash out the radiator every other day or so, sometimes more sometimes less, and clean the air filter then. We have 2 9750sts's, one's a 2000 and the one we just got this past year is a 2003. We have not had very much trouble with them in that respect. I will keep that in mind if we do, thanks!

Complaint or Symptom:

The engine air intake system has a problem. It may show up as any of the following complaints:

Plugged filters or dirty filters
Air restriction light comes on
Low power
Excessive exhaust smoke
Solution:

FILTER HOUSING AND TUBES
Visually inspect the air filter housing for leak points. Does the lid fit tight? Are there gaps where the tubes fit together? These joints will be somewhat loose, they are not totally air tight by design. On 10 and 50 series combines, are there any cracks in these plastic parts?

FILTERS
If the primary ( outside ) filter is plugged and dirty in a specific area, this can indicate a leak in the filter housing. Refer to the operator's manual for complete instructions on inspecting the filters with a light. Wash these filters as instructed in the manual. If compressed air is used, always blow air from the inside out. Sooty filters indicate an exhaust system leak. Also see solution 6145.

ASPIRATOR
Be sure the check valve is not stuck. Inspect the hose to be sure that it is tight and that it is not kinked, cracked or collapsed. Is the muffler worn out? Any of these problems with the aspirator will cause the filters to get dirty prematurely.


LOW ENGINE POWER AND / OR EXCESSIVE BLACK EXHAUST SMOKE
Any problem with the air intake system may result in low power and / or smoke. Also consider bad injectors, pump out of time, low turbo boost, engine fan on backwards, low cetane fuel or a hole in the intercooler. Also see solutions 5142, 6028 and 6295.

Re: early sts owners-fast and cheap way to fix int

We're yet to have any problems with our filter on our 9650sts, i've taken the filters out but they still looked brand new.

Re: early sts owners-fast and cheap way to fix int

STS = Sucks Tons of Sh!t into the air filter. Is that a good enough sub for superior threshing system factory?

If you have jacked with your muffler/aspirator i'd start there.

Re: early sts owners-fast and cheap way to fix int

Tom, I really don't know what's going on because we have went through everything just trying to find a leak or something like your dtac message said. Now our neighbor has a 9550 and has no problems at all. Why could it be just us??? Anyway, this seems to work so we'll leave it like this.

One thing I did notice is the dirt is just blowing out of the side near where in intake is so it's no wonder that it used to plug up. We also have more dirt this year since the beans were swimming





No not really since nothing can thresh green-stemed beans like an sts
Anyway we left the muffler alone for now.

Re: early sts owners-fast and cheap way to fix int

Have you ever let the right back lading going in to the engine compartment open to see if the air flow is different. Also the straw chopper deflector, if you sit it down a little so it will hit the ground faster will that stop the dust better. Have been told be a JD company guy to make the left side chopper fins adjust to not throw it out all the way out.
I don't know how you can tell if this works, would have to do some experimenting and see if that works.
If what you are doing works that is great, the tube is up high to get it out of the dust.

Re: early sts owners-fast and cheap way to fix int

Im in process of converting my machines once again because of all these related problems. The radiator fans are so aggressive that they pull tons of dust into the air box where the engine breathes and passes it through the air stack and past the engine, you can actually see the dust blast in the left side view mirror as it exits the engine compartment. Im recoring a radiator this winter because of all this dust wearing out the core. I have a solution for air cleaner/inline precleaner/ exhaust ejector setups that has proven to work great as far as filter cleanliness, the only thing the filters saw was very fine powder/ lighter than air dust. Now if I could stop the fan from pulling in all this dust from the outside of the machine It would be a great system. I have thoughts of STS similar scoop for the radiator door but still checking into parts for that setup. I have already tried ejective precleaners and they cant stand up to all the trash and chaff that airborn even up as high as the hopper toppers so I canned those ideas. I heard from a friend that his cousin running STS rigs piped his intake instead of from the rotary screen box around the side of the machine along the hopper and up front near the cab, but in conditions that Im in theres dust everywhere and it follows you around with the breeze so I dont see this being the ticket either, no to mention alot of plumbing. I guess similar to what we used to do to the old 9900 pickers.
Dave I can see your setup working in many conditions but not if the chaff flys high which is possible.
Ill let you know what I decide to do as far as scoops go, for a time I thought the STS scoop setup would work on my 9650 walker but there was deere pips stating not to do this mod on walker machines, why I dont know and would like to know if anyone has tried anyway, I think the rotary screens are the same with same door size making the other parts not to much problem.

Re: early sts owners-fast and cheap way to fix int

Great idea. We finished beans 2 weeks ago and before I saw this or I'da tried it. Cleaning the air cleaner 2 or more times a day is a pain but that engine will let ya know it if it gets starved for air. We're running a 635F hydra flex on our 9650STS which means theres a lot of crop being swallowed up to create a lotta dust in a very small area. It's unavoidable. We're now in 18-19% moisture corn with an 8 row head and it is far less dusty.

If we study it long enough I think we could come up with a larger air filter canister and a better place to draw the air from.

With that high velocity cooling fan there seems to be very little trash that gets hung up in the engine compartment which is probably the main reason for it. Radiator cooling seems more than adequate.

tom:

you hit it spot on...after this issue was brought to my attention i was watching today as we were cutting soybeans again...our right side section of the chopper barely throws the debris to the outside edge of the rear tire while the left side blasts it 15' past lol.

Re: early sts owners-fast and cheap way to fix int

You must not have the discharge beater deflector fins that the newer machines have. They help to even out material flow into the chopper. There might be a DTAC solution for part #s and install instructions. Tom?

This one.

Solution Number: 63163

Solution Summary: 8 March 2004 DPAC SOLUTION CONFUSION EXISTS AS TO WHICH DISCHARGE BEATER VANES TO USE------All STS Combines

Publication Date: Mar 11 2004


--------------------------------------------------------------------------------

**Paper copies of solutions may not be the most current solutions**

Complaint or Symptom:

Confusion exists as to which discharge beater vanes to use.


Problem or Situation:

A running change in model year 2002 caused the floor to be made longer and to use three vanes, one left and two right. Through field tests, it was determined that the left vane was not needed, so the floor was shortened and two vanes were adopted in 2004.


Solution:

H205284 left vane is cancelled and H205283 right vane will be soon. Because of changes in the floor, only two vanes (H214321) are now needed. H214321 is really a generic vane, i.e. it is neither left or right.



Whenever a new (short) discharge floor is installed, BH84190 should be installed too. BH84190 contains two H214321 vanes and hardware.



You cannot install old vanes ( H205283 and H205284) on a new (short) floor, but you can install the two new H214321 vanes on an old (long) floor.


Additional Information:

When installing BH84190 vanes (H214321) you will notice that there are three holes in each vane, yet only two bolts for each vane are provided. Place one bolt in the slot on the tapered end for either an old or new floor. Place the other bolt in the center slot if you have a new floor or in the end slot if you have an old floor. This information is not provided with the parts.

Re: early sts owners-fast and cheap way to fix int

No I never have but when you said the thing about the chopper I think that is it. But we spread it as wide as we can so the field cultivator can go through no prob in the spring.

In order to do this a little better you can get an air can of of a 70 series 4wd and put a precleaner on top. They both have the same dimensions .

Tom, can customers use DTAC with our JD username and password or is that only for guys like you?
