Combines Electronic Bosch fuel pump n0402196702 on a 9600 combine

Yves, Comment ca vaIJ Bien j'espere. The connector is called a Packard Weatherpack. Available at your John Deere dealer. Have to get back to you on those error codes, but the engine run out of timing one day a weekIJ Do you mean that the engine is out of time nowIJ The engine timing is not electrically controlled. Only the fuel delivery. Comprenez-vousIJ Bon Chance, Joe

The engine is still running,but with his problem of engine backfire and a small lost of power. A dealer at Montral,tell me that on this engine, it's suppose to have two (2) speeds sensors on the front cover of this 6076 J.D. engine. One screw on the front top of the engine with a resistance of 300-700 ohms. The other one is bolt on( 2 bolts) and a "o ring". He is bolting on the front cover too,under the alternator and a resistance of 2700-3300 ohms.In the shop manual,for the code 44 (Main board type B and a injection system type b),the specification for the connector X-2 is between 300 and 700 ohms. On my engine ,i had only one speed sensor(RE 43511) with 3026 ohms.It is suppose to be no good but the dealer tell me it is good. I need some help. Yves

Yves, Before you check anything else, check the injection pump timing. The symptoms you describe do not sound like an electrical problem at all. It sounds like the engine is out of time, most probably because the crankshaft gear has slipped. It is easy to find TDC on the engine to confirm the pump timing. Ask your dealer how this is done. Do not operate this engine until you find out weather it is in time or not, serious damage could result result. Bon Chance, Joe

Thanks a lot. I don't think it is a mechanical problem because the engine can run very well for 6 or7 days.If it was the gear of the front cover,the problem gone a be there always.The problem is still there since 7 years.Yes 7 years.If the engine run out of timing,may be the crankshaft would be broken. I had to change the amphenol of the X-12 con- nectors.When the trouble arrive (code 34).The operator stop the engine,get down the cabine,go to the engine compartiment,unscrew the connector of the Bosch pump,screw the connector,get down the engine compartiment,get in the cabine,restart the engine and all is ok, sometines for 5 or 6 days or 2 or 3 hrs.Before the code 34 appear,the driver tell me that he can feel that the problem is comming because the engine lost approx. 80 R.P.M. and he lost some power.IJIJIJIJIJIJIJIJIJIJIJIJIJ Merci beaucoup,pratique ton franais.

Yves, J'etude francais puor deux ans, mais il y a cinquant ans...J'oubliez... Obviously you speak better english than my French. Yep, 7 years is a long time. Are you talking about the circular metal connector on the Bosch pump, has two pinsIJ Connects to the fuel temperature senderIJ If so, I told you wrong earlier, that is a Deutsch connector.It is very common for those to get dirty and cause the problem you describe. What happens is the ECU thinks that the fuel is too dense and de-rates the fuel delivery. I am sorry that I have been of little help to you.

May be if you try too write a little bit in french,in some years it will be easeyer for you to speak,write and read. For the connector,it is the one with 7 wires.On the pump,we can find 3 electrical item.Fuel shut off (1 wire),fuel temperature sending unit (2 wires),and the other one 7 wire i think for the rack,the primairy speed sensor and.....etc. As i said earlier,one of the canadian dealers of J.D.,tell me itis suppose too have 2 sennsors on the engine front cover.But i found only one.I was not abble to persuade the dealer,so,i take somes pictures and send to the dealer last week.I am waiting.If you had a -mail,may be i can send you those pictures.On one of them,we can see a part of the connector X-12 on the Bosch fuel pump. May be it is personnal but: Are you a mechanic man working for J.D. Are you an operator of J.D. combine or are you a salwesman for J.D. Thanks Yves N.B.Send me your -mail you gone a see my 9600 engine pictures..

Sorry i forget. If you know the resistance in OHMS for the temperature sensor,i'll appreciate this information too. May be the fuel pressure tap on the line betwen the fuel filter and the primmer pump Yves

Yves, I'm going to go out and look over a 9600 today to re-familiarize myself with the problem area. I was a mechanic for a Deere dealer. I still do o lot of work on Deere combines (and other brands),but now I am self-employed. My e-mail address is at the top of this post. As for my French, well....you are right, but I have met only one French-speaking person in 15 years. An engineer from Bordeaux who was in the U.S. for training. It is difficult to practice under these circumstances. The reason I studied French in collegeut of a class of 23 students,I was the only man. I used to look forward to that class every day...sat next to a little blonde cheerleader named Cathy..with all those distractions, it's a wonder I learned more than a few words...well that's another story. Send me that picture Yves, and we'll get to the bottom of this. Bon Chance, Joe

There are two speed sensors one is a back up that shuts down the fuel if something sticks and the

Do you know if the n of the sensor in the front engine cover is RE12180,RE43511,RE71121 or RE508195. And what is the resistance of this sensor. It is not the model with and o ring.
