Anyone remember the discussion about threading the exhaust manifold for installing a threaded pipe to aid in keeping rain out from running down the muffler? I think it was just a few weeks ago but I can't seem to find it. Thanks, Mike. ------------- 39B 42B 48C SFW 52Cub Cub Cadet 70 S14 Speedex M14 Speedex S18 Speedex |

1 1/4 taper pipe tap for a 1 1/4 nipple.

I remember something about rain caps not keeping water out of manifold. And suggestions on tapping and a brazing, and a modification with exhaust piping. ------------- 1938 B, 79 Dynamark 11/36 6spd, 95 Weed-Eater 16hp, 2010 Bolens 14hp |

The threads help for a while, but eventually let water in! --- easiest way is to braze an upside down funnel above the manifold on the muffler pipe. --- did this on a 806 and a couple other tractors, does work. ------------- http://machinebuildersnetwork.com/ |

That is why water pipes always leak right! |

if you thread the pipe into the manifold, and still get some water........... It is coming down the exhaust pipe thru the muffle......... the pipe thread don't leak. ------------- Like them all, but love the "B"s. |

I agree with ac fleet. Not the easiest thing to do though. I wonder, has anyone ever tried Gorilla glue to do this? Can it withstand the high temp? ------------- "Allis-Express" 19?? WC / 1941 C / 1952 CA / 1956 WD45 / 1957 WD45 / 1958 D-17 |

| My preference is to buy the OEM style of muffler which shields that area, then cover the exhaust pipe with a rain cap or can when left outside. |

I did the shied over the manifold opening around the internal muffler pipe thing until I picked up my 1 1/4" taper pipe to see what size drill it would take to ream it out for the tap. I found it is cast to the correct diameter. All the Oliver's I grew up using came from the factory with a threaded pipe nipple that the muffler pipe slid over. The pipe nipple is a one time deal for the life time of the tractor with a (proper) rain cap. All my tractors set out year around and some only get started every couple years or longer. It is my insurance policy. |

Any idea what muffler number you use Dick? ------------- "Allis-Express" 19?? WC / 1941 C / 1952 CA / 1956 WD45 / 1957 WD45 / 1958 D-17 |

The one I use is a Ford inline under the red belly. I took a 1 1/4" nipple from their stock with me to the mufflers at Rural King and found one that fit and then put the nipple back. I cut and thread my own nipples at the factory. |

Farmall Cubs use a threaded pipe into exhaust manifold. ------------- 39B 42B 48C SFW 52Cub Cub Cadet 70 S14 Speedex M14 Speedex S18 Speedex |
