| Sounds like a timing thing to me something must have jumped or broke. The first place I would start is under the valve cover , then off to the pump drive. |

just to update you i brought the tractor in the shop and took the hood off and check for fuel at the injector it was spitting fuel out so then i took the valve cover off and the valve were all moving and they would have a little movement when they were close so i took out the glow plug and i could here and feel compression on # 1 cylinder but not on #2 and #3 so i put air in the glow plug hole and on 1 on tdc it would roll the engine but when i did it to 2 & 3 i could here and feel the air come out of the other one so i think i have a bad head gasket ( best case sanarrow ) (spelling ) will be taking the head off tomorrow to see how bad it can get but it make sense to me it was trying too run on one cylinder tanks for all the help so far will let you know what i find B:-) Dnoym |

| Head gasket was my first thought reading this. Sounds like that is your issue. The thing that gave it away was you said it was black smoking but cranking faster. Good luck. |

If you could contact Affolders equipment in Berne, Indiana they can get one. Don't know the price would be any better but might be worth the hassle. They are a long time AC and now Agco dealer. ------------- When you find yourself in a hole,PUT DOWN THE SHOVEL!!! |

| Try doing an internet serarch for them. You would be surprised what you can find. I have gotten some great deals on parts. Its worth a shot. You might even find someone who specializes in these parts. |

It will be a long shot trying Affolders as they just had a fire destroy theri shop. Insurance made them throw away all parts. they are a little stressed at the moment. You could try dont know if it would be worth it. ------------- ryan 1984 8070 FWA,1979 7060,1975 7040,1971 190,1960 D-17D,1957 D-14, 196? D-19G, 1975 5040,1971? 160,1994 R62 |
