I have need to replace the tube that connects the turbine outlet to the exhaust elbow on an HD16M. Its NLA from the dealers. I've tried local truck shops and parts houses with no luck. Anyone ever come across a source for a replacement? The part I need is #7 in the diagram.  |

| Eliminated both diffuser and cast elbow on one of my 11`s. Used standard truck turbo flange with lightweight exhaust elbow, so didnt need extra support pedestal. Turbo provided all the support |

You might want to try Arnold's Allis Chalmers in Colusa, CA- they've been able to help me out with all my HD11 manifold problems. www.arnoldsallischalmers.com |

| My 7G had the educator for the air filter already gone when I got it(similar to the illustration on the right), the original attached to the hood stack was gone and a hole enlarged for commercial exhaust piping. I have often considered reattaching a home made educator for the air filter to pull pre-cleaner dirt but never got to it. My exhaust elbow does not fit tight to the turbo due to erosion so it seeps some, have also never tried to locate any pieces to correct that issue. |
