Has anyone heard or had any troubles with the Susi engines? My neighbor told me of a couple stories that farmers were having with Susi engines in R-76's.
Susi Engines

What problems have you been hearing. I've been very honest about my poor power on my 2008 A-75 but the updates in the computer programing has that fixed. With another update to be installed this spring. Other than that my only thing has been putting a tractor engine on the combine they should have changed a few filter locations on the engine. To change the fuel filters you need a young monkey to crawl over the engine and get down behind it to even see the filters. On the tractor that location is right out in the open.
So what problems are you hearing of and on what year and model?

Only problem we had on our 08 R75 was the fuel supply pump to the filters went out. Ran great one day , parked it and a couple days later would not go over 1800 rpm's. If it would it would slowly fall off the rpm. Error code on Fieldstar monitor was correct. Never fails though it happened on a Sat afternoon. I will agree on the filter locations. You have to remove a fuel line to replace the cannister oil filter as of now.

Neightbor has a 76. They have done some updates to it and he hasn't had a chance to run it since they did it the second time. He says it won't lug as well as his old 72 with the M11. Other than that I think it has plenty of power the way he talks.
No problems with Sisu for us. First Sisu's in combines were teir 3 and we upgraded software a couple times. Once for soot in oil and another for better torque curve in combine operation. Kind of the same things we went threw with the first Cummins powered machines. Maybe the guy was talking radiator or intercooler core plugging which was a problem. This could depower machine and or cause heating. This was for the most part fixed with the latest rotary screen update. Looks like for '10 they will have a couple swirling blades in front of intercooler core and that should further improve situation. Big thing with the latest update kit is the blades need to be close to wall, seal around box has to be tight, and screen needs to spin up to proper RPM. I think if the guys are having HP issue they need to look at what could be sucking up the HP in the cylinder.
1923Gleaner, I can't help myself. On the Natural Flow you can easily service anything on front of motor.
Scottinswil, Remove short hex spacer from filter head and reinstall the line. This spacer was removed on the '09 production.

To answer the question about what the problems were, one farmer bought a new r-76 and only ran it a few hours and the engine blew. I don't know what caused it. Another farmer who puts a lot of hours on combines in a year was having troubles with the combine holding power. One day it would run fine and then it would loose power or lug down. I haven't talk to them to ask any questions about their problems. I bought a r-76 this winter and haven't had a chance to run it and then I heard some of these stories, I was wondering if they just isolated. Thanks

1923 Gleaner, the models were 09 r-76. I talked to a farmer who had a r-75 and had some updates on the engine and he said that it had lots of power now and he hasn't had any problems.
nddan: I understand what your saying. I ask a company man why they didn't move the filters for the combine. Just another example of you should be a mechanic before you can be allowed to design anything.
I understand there is another update to the radiator screen. I never had any trouble with the original rubber seal. I just put a spray of silicone under the seal a couple times so she wouldn't stick. Wish I had stayed with the rubber seal system.
Yes I also have heard that this latest update has solved the power issue with the sisu. Too bad some of us had to go thru a whole season being told "We've never heard anyone else having any power problems". Then talk to a few guys and find this problem was happening all over but company boys wanting to keep it "in house".
Hopefully after the 10 Wheat harvest I can report back to you boys that all is well and it's a Wheat eating SOB. But it shouldn't take a company 3 years to get things straightened out.

Had a new r66 this year that was short on power. Updated software did help, but there were also alot of plastic shavings in the fuel tank. We went through a few sets of fuel filters and cleaned the in-line screen below engine a couple times also. There also is a screen in tank for any body that has never ran into that. We did still feel that the combine was short on power in high moisture corn but we were also having trouble with concave and seperator grate plugging up. I think with a different rotor set up and some changes to the helical bars we will resolve plugging issues and reduce power consumption also.
We have had a 65 and now a R66, both were lacking power until software was done, greatly improved torque and hp but still sucks the fuel although the newer engines all seem to. I agree the fuel filters are in a dumb location along with the centrifugal oil spinner filter, we had to have a mechanice come out and he had to make some changes just so we could get the cap off of the oil filter, like you guys all say a mechanic should have the final say on alot of these things and Agco should pay more attention to these details. We have had the latest update on the rotary screen and it still gets far too dirty, it sucks in way too much garbage and i am still really pissed over this, Agco has already heard about this and is going to continue to hear about it along with the longer auger. Our auger will not come out if it has any grain in it, if you fill on the go you have to pretty much either leave it out or if you do put it in have a couple guys help lift it out of the cradle, its been a full grain season and a full fall season and this is still not resolved, Agco has to get these things fixed.

Your rotary screen. We had a problem with it being worse than before, but ours was not adjusted properly from factory. Once it was adjusted properly didn't need to clean it nearly as much. I only once wanted to try the auger full to see how it would work for that reason...it came up. But I only tried it once.
I think I should clarify what I have been through with this screen. I know this topic heading is sisu engine but it's all a problem.
My 2008 A-75 came out with the rubber seal and slow turning screen. I was happy with it as no trash got in. Only problem is the seal would stick if she set for a few days. My solution was a spray of silicone under the seal, worked great. Then came the field change to the fins in 2009. Pop riveted fins to the screen, welded a ring to my door, no touch up paint for the burned welds. They wouldn't do this to a $60,000 Cadillac but with a $220,000 combine it's OK!

Anyway when I went to the field 1 1/2 bin of wheat the air filter light went on. I change both inner and outer filters new for the season. Filter was packed full of short straw and chaff. They didn't speed up the screen. They told me how to speed it up, I did and got 3 bins full cut before the same thing happened. They came out moved the screen closer. I got through harvest but 2 blades have broken off the fin pieces they put on the screen. Turning the speed (I believe its 215 rpm) the screens are not balanced so they go egg shaped at that speed. Then the blades would scrape the door in spots. It's a joke!!! I still have the old seal and stainless wear ring and have said I'll put it back on. Gleaner does not want me to. Why do they need to go to a hydraulic driven screen when the old propeller worked since the early 1960's. You would have thought they would have changed the whole door instead of grind off the rivets from the stainless steel ring then weld a ring on. They even plugged the rivet holes with silicone. Strictly mickey mouse. Can't wait to see what the change over will be this season!

I bought an LT90A this spring with the 4- cylinder sisu. I wasn't happy when I first got it, it seemed gutless. Now it has over 300 hours on it and it pulls like a bear. I've pulled it down to 1200 rpm and it keeps walking. They start excellent. I haven't had it plugged in all winter. I preheat it for about 30 seconds and it starts like a gas tractor.
Been a Gleaner man all my life.. Over 7500 hours on a "L" before I traded for my first Rotary,, a R50 with the air cooled engine. Like the combine but not so much the engine.
Anyway my last machine is a S67... I took a step backwards from a R75 and knew well the full sized combine and smaller engine as I had several 62s and 65s..
Well this was worst.. Just sitting still in the driveway spinning the machine sucked 80% power. Got it too the field and it was all it could do to pull level ground in second gear with 2/3s bin of grain.. I called the dealer for help.. Did it throw any engine codes..???? No. Nothing is wrong then.!!!! Its all in your head,, trading down from a 75 to a 67. I could not fill the bin with grain without stopping to blow out the radiator.. Im not talking chaff,, Im talking stalks with heads sucked flat against the radiator fins. The longest drawn out wheat harvest in my life.
Still no power,, and a rotor screen that did nothing.. The dealer kept blaming me for not spending the extra $5000 for the reverse fan kit. I told him,, a reverse fan does nothing with the bushel of straw left in the screen system.
I lost a much needed 500 acre custom job I depended on to help out with the $38,000 combine payment.
Dealer came out and looked at the rotor screen.. I showed them I could stick my hand between the rotor screen frame and drum. Well they fixed that with a entire new door. But my oil cooler,, air to air and radiator looked like they just threw them onto a gravel driveway with bent up fins and a ( still leaking radiator) Problem solved. Only need to clean the radiator a few times a week now.
As for the power issue,, it turned out the waste gate was not shutting all the way and only built 12 lbs of boost pressure.. Since the computer did not know the problem ,, it just threw huge amounts of fuel at a air starved engine,, and mudded up the oil so bad in 20 hours I had to dump oil. After getting the waste gate fixed,, I had as much if not a tad more hp than any Cummins in a 6s sized machine.
That fall I went to cut beans.. Well we had a major drought and only cut 15 acres on hard packed dry soil and cut bait and called the beans a loss. The next year I had some nice beans. The first thing I told the dealer when I walked up to this combine with the large tires,, was " how does this effect the header angles"?????????
Well I made this comment a dozen times over that first year... Went out to cut beans the 2nd year and I noticed it was picking up soil crust into the header real bad. .I called the dealer again,, ( are we missing something here,,, this cant be right) He told me he had 5 machines out with the same large tires and headers with no problems,. about 20 minutes after my phone call,, the header dove into the crust with the most gut twisting noise ever.. When I raised the header the knife and wobble box were still in the ground.
It cost me $18,000 in parts alone to repair. The Agco tech,, set the auto header controls and we took off with a rebuild header and made it about 50 feet on level ground before it sucked into the soil again. I was going a whopping 2mph when it happen again. Tore a bunch of stuff up again,, but since I used up all the spare parts in a 800 mile area,, we were heating up control arms and bending them,, and hammering feather sheets to get it going again.
The next day the dealer tech shows up with a AGCO,, header "shim kit".. My 2 year old header at that time has never been the same since.
My comment,, to Agco,, Gleaner.. I have been a loyal customer for 40+ years. When ever I hear of another farmers combine laying down I have always been the first to offer use of my Gleaner to finish up,,,, and to help sell them on the silver machine and not the red and green. . But after word got around about my "dealer service",, I have not seen another Gleaner in the area since. all of the loyal Gleaner farmers I know,, have switch too green and red.. I wonder why..
Now lets not get me going about my Challenger,,, MT555D.... Seems to suck money away faster than I can put it back in the bank,, I still feel that both the Gleaner and Challenger are as good if not better than any other color,, but without fair,, and good dealer support one is ahead to buy a no name Russian combine or tractor with no dealer in the USA.. Cheaper in the long run.

Hp issues on a Diesel engine are pretty simple. You need both air and fuel. If you don't have one you won't get the other. Always check to make sure one has adequate fuel supply and no boost losses. Wastegates fail, clamps fail, intercoolers fail, hoses fail, filters plug, screens plug, pumps fail, etc.
