Mid-Missouri | I have been having trouble with the center belt on an FD70 not feeding. It sounds and looks like it will stop when getting into heavier soybeans at times.
I attempted to tighten the belt tension but instead of the front idler appearing to move forward, it instead just compressed the tension springs. Maybe it was already tight?
I lowered the poly pan with three metal straps and put a downward bow in them because I had heard they can get pushed up into the bottom of the belt.
I am planning on installing more fingers in the auger, but don't think that is the problem.
It seems that at times, when it stops, I can hear a squeal. Could it be hydraulics bypassing? I also think a time or two when it would plug, if I raised the header up, the belt would try to turn more than when on the ground. Reversing the header always gets it going again.
Thoughts? |

north central Kansas | When I had this problem with my 974 I finally found my feederhouse floor had worn through and was causing beans to back up in the front of the feederhouse and eventually stop the center draper. Not sure if it's yours but it took me a while to drop the head and look at the combine instead of the header. |

southeast nebraska | Mine is doing the exact same thing. Head is a few years old on a brand new combine. Looking for answers as well

Parshall, ND | It's the orfice that runs the center belt, we change our out every 2 years or so because it progressively gets worse and worse stopping all the time. Put in the new orfice and it runs like brand new again. |

Trenton, KY | Ours did the same thing and the technician that came out tightened the relief valve down by 1/8 turn and it's never given trouble since. I believe it must have either been set right on the line, or it had gotten a little weak. |

McCanna, ND | I've had it happen. Where the canvas wraps around the back side of the head next to the auger dirt can build up there and stop the canvas. Took me a couple times to find it. We have a lot of dirt related issues with our draper heads |

|
NW Pa. | Make sure the feed auger clearance is correct. If its to high the canvas will wrap. It says in the manual what it has to be but cant remember right now. |

|
Mid-Missouri | Would you recall where the orifice is and/or part number? |
|
| |
|
Mid-Missouri | Do you know where the relief valve is located? Yours also an fd70? |
|
| |
|
Parshall, ND | The orfice is easy to access if you tilt the head all the way forward and it's close to the top of the adapter on the left side. It's silver and easy to find. I don't have the part # handy right now. If you can't find it, I could take a picture later if you need it |

Southern Alberta | If you have the canvas pieces that cover the front of the center draper, take them off. It traps the dirt and fine material in there and causes so much resistance that the center draper trips the relief or slips the belt. Removing the front covers allows the dirt and fines to flip out the front. Are all the cleats on your center draper? Once they start to fall off it has trouble pushing the crop into the center drum. |

Mid-Missouri | It sounds like it is in front of the filter location? You are referring to an FD70? I would love a picture if it isn't an inconvenience. I wonder why it would wear out? Do you think it only affects the center belt? |

Mid-Missouri | Some of the tread has come off. I have cut the loose tails off. The original belt fed just fine with practically no tread.
I am not sure what canvas piece or front cover you refer to. I don't want to take anything off that would increase grain loss. I have fought grain loss since day one in certain dry conditions. The recent purchase of an air bar has been a big help though. |

West central IL | its the pressure relief valve, the spring was stuck in ours smacked it with a hammer and center belt started working again, I took it out before hitting it, figured I wasn't out anything if that was it one is for the side belts I thinks its 2500 psi one for the middle is 1500 |

|
Parshall, ND | It's an FD-70. Yeah it only affects the center belt to my knowledge

NE North Dakota | It is V 3 in the parts book the Case IH number is 87597539 |

Mid-Missouri | Thank you very much. That was my guess after looking at MacDon parts catalog.
Many thanks to all. |

Trenton, KY | I'd have to look at our parts book to know which location it is, but I believe Buhler is right about it being V3. After having trouble and it just being a relief valve I called MacDon and wrote down what each location's function was, because in the field if you all of a sudden have trouble, a simple adjustment of the relief valve probably will get it going just fine. |

|
Mid-Missouri | I believe my problem was the relief valve set too low for the center belt. To raise pressure, tighten the allen as pictured above slightly. Thanks again. |
