I have a 1956 Fordson Petrol/Kero tractor. The inlet/exhaust manifold is cracked. Does anyone know if these manifolds are still available or what is the best repair option?IP: Logged |

Not sure if the petrol / kero model uses the same manifold(s) as the diesel. Bare - Co has a australian site, here is a link to the U.S site that has a picture of the exhaust manifold. http://bare-co.com/files/ford2001/frd46.htm Scott IP: Logged |

I just looked at a picture of Brian's Major in an old post. The gas/kerosene and diesel manifolds are not the same. I know of a few places that sell diesel manifolds, but none that sell gas/kerosene ones,yet.IP: Logged |

I am afraid you have a big problem. The paraffin tractor manifold is totally different to all other Major ones and is subject to thermal cracking. It is also impossible to weld as the metal seems to form crystals and the welding process just burns holes in it.This is because of the high temperatures generated by these tractors. In work, in the dark, the manifold glows dark red and a four inch flame comes from the exhaust. This is perfectly normal. There were very few of these tractors built, around 25,000 spark ignition tractors and of these, only a small percentage were petrol/paraffin. Emiel knows of a company that still casts parts of the assembly. Whether they can do the complete unit I do not know. ------------------ Kind regards Brian IP: Logged |

Hi,Unfortunately I must tell you guys that this company does not supply new manifolds. The story is as follows; A couple off years I met with some guys from the northern part of the netherlands, who supplied then reproduction parts for Fordsons. Also they had a hot spot valve for the kerosene manifold reproduced. These two brothers did not have a company, but yust doing this for hobby and they had a good contact with a metal foundry. I was in the process with them to buy such a valve, when my computer crashed, and I lost their email adres as well ass their telephone number. I hope to meet them again so I can polish up the contacts. Best regards Emiel IP: Logged |

Hi,I was speaking to a friend of mine regarding your problem and he said that is is possible but not easy. The problem is as Brian so rightly pointed out, the iron forms large crystals as a result of the very high operating temperature. What you need to do is get the manifold annealed. With cast iron this is not easy as it involves very precise temperature control. The manifold needs to be heated up to over its plastic state but not it's liquid state. In other words over 1250 C but less than 1400 C where it becomes a molten mess. It needs to be held there for about half an hour and then cooled very slowly. If possible pack it in hot casting sand and just turn the oven off. Once this is done it will weld just like a new casting. As for who might be able to do the job is anyones guess, but I would start at any large place that does cylinder head crack repairs to look for someone with the right oven. Good luck, Frank.
