| I am new to the forum. I recently purchased an allis chalmers b tractor that needs work. The water pump was leaking so i ordered a new one. I have also purchased manuals on this tractor for servicing an maintenance. I have been through books i got all all over the internet and for the life of me can't find torque spec for reinstalling water pump. Does anyone know what it is. |

Welcome to a great forum. I just put one on a B and just tightened it up. I'm sure someone will know if there is a torque spec. Post some pics of your tractor. Where in WI are you? ------------- Everything is impossible until someone does it! WD45-trip loader 1947 c w/woods belly mower, 1939 B, #3 sickle mower 1944 B, 2 1948 G's. Misc other equipment that my wife calls JUNK! |

You can look up the torque spec for your bolt size on the internet, you also need to know the SAE grade also. Probably grade 5. ------------- 1938 B, 79 Dynamark 11/36 6spd, 95 Weed-Eater 16hp, 2010 Bolens 14hp |

| I put one on my B. I didn't realize there was a torque spec. I did just did as mdm1 did, just tighten it. It works and don't leak, I figure it's good to go. |

| I used no sealant at all. Just the gasket that came with the pump. I thought about using something, but I haven't had a problem yet. |

nobody had a torque wrench in 1940 ... Most mechanics are just familiar with "tight" for a given size bolt.. If your not as experienced, then I would use a grade 5 torque for that size bolt and call it good. ------------- Like them all, but love the "B"s. |

Page B-C-15 in the shop manual I have says "tighten securely" for the water pump mounting bolts. http://geraldj.networkiowa.com/Trees/Allis-Chalmers-G-B-C-CA-Service.pdf" rel="nofollow - http://geraldj.networkiowa.com/Trees/Allis-Chalmers-G-B-C-CA-Service.pdf Gerald J. |

Use anti-seize on the bolt threads just in case you or somebody else ever needs to work on it again.
