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.

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

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.

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.
