I have a 6v92 Turbo in a 1979 MCI-9. We were recently out on a trip when the exhaust came loose from the turbo. The exhaust came pipe came loose right where it enters the turbo and also broke where the pipe enters the muffler. The flange that came loose has three compression type rings and fits onto a sleeve that is connected to the turbo. I am wondering if there is a clamp or something that holds it back on. We wired the pipe back on to get us back home, but the pipe feels loose and does not fit tight onto the sleeve. I thought that maybe if I had the muffler welded back on to the pipe, this may give some support to the pipe and hold it onto the sleeve coming out of the turbo. I called MCI and a new sleeve and flange piece is going to be way over 200 bucks. I thought about tacking the flange onto the sleeve, but I would rather try to get it the way it is suppose to be. I need some help figuring out how to put it back on right and am kinda hard pressed for cash, so I wanted to get some experienced opinions. Thanks JR |

I bought a similar piece from Luke @ US Coach and I think it was over $200, also. You might try a welding shop. He could tell you if yours could be repaired which might save you a few dollars. David Anderson |

Sounds as if you have lost part (or all) of the clamp so you'll probably have to buy the proper piece, since it is virtually impossible to succesfully weld to the ultra hard (read- exotic alloy) turbo, and get it to last. There is a tremendous amount of expansion and contraction in that area due to turbo temps, and it's even worse on the downstream side. The clamps is a really hard, springy stainless steel alloy to take the high temps of the turbo. Good Luck. ...JJ |

As what TD & JJ said is NOT to weld at flex-joint or any joint for that matter or you will have bigger crack & leak later. Already report of badly burn an Eagle from disconnect joint at turbo while acceleration. The best welder would not guarantee it. There is reason why factory equip the way it is……Durability & servicing & cost period. I am sure you find used parts at old bus charter garages or bus salvage yard. Ask in WoBN's The Flea Market. http://www.busnut.com/cgi-bin/bbs/discus.cgi FWIW Sojourn for Christ, Jerry |

I have looked at pics of others on the net and there is no clamp that goes on this piece from what I can tell. It appears to just slip over the sleeve and maybe the compression rings hold it on, but when I put it on, it does not seem tight, it will move around a lot and come loose if you pull on it. When the bus is running, it does not leak at all around this fitting. I'm thinking when I weld the pipe back to the muffler, that may help hold it onto the sleeve coming out of the turbo. I may be wrong, but I can't tell that anything is broken on it and everyone that has looked at it really doesn't know much about it. |

M9 Man, It seems you are dealing with a different piece of pipe than what I replaced. Take a digital picture of it and send it to Luke @ US Coach for a diagnosis. He will be totally honest with you about what you need to do. I think just about everyone on the board will agree with that assessment. David Anderson |

M9 Man, Our singing group is running a '84' MC-9 with a 6V-92. The exhaust on ours is a standard 5" system. If I'm not mistaken, the collar that you're talking about is a standard peice. I'd take your old one and start looking around. As far as the clamp, this a a "V type" clamp. I replaced this very clamp that you're talking about last December. I got the clamp from a local truck parts supplier. Seems like it cost around $15.00. While I was at it, I replaced the muffler to. Now the muffler uses a different type of clamp. It's a "band clamp". I hope this will help you. Glenn MC-9 Tallulah Falls, Ga. |

I appreciate your input. These suggestions are helping me, but from what I can figure out, the part on my exhaust system did not have a clamp or anything to start with. The compression rings just seem to hold it in place, but the fit is still a loose fit when I put it back on. Is that how it is suppose to be?? does the attachment to the muffler help hold this in place?? |

Re: "the part on my exhaust system did not have a clamp or anything to start with" My MC9 has clamps. What these guys are trying to tell ya' is, whoever you bought the bus from may have neglected to check to see if the clamps fell off, or weren't installed after a repair. Take a picture and email it to Luke. If you don't have a digital camera, use whatever camera you have and use the facilities at Walmart, Walgreens, CVS or wherever, to digitize the film or print for use in your computer. Luck be with ya'.. |
