| I have a bus in the shop with a bad ICP . When I went to work on it I checked the VGT . It is stuck .It's pushed in and won't return Turbo is giving a full boost of pressure . What would happen or could happen if I leave it alone ?Since I have been here I have replaced 4 turbos in a 13 bus fleet . Would it be wise to just leave it alone since it is giving boost ? Thanks |

| If the vgt is stuck it will work like a really crappy waste gate turbo. You will have excessive egts. Depending on the turbo you can remove most of them and clean the carbon and crap off the unison ring. I would not recommend just leaving it |

Vally, if you wouldn't mind, I'm doing an unscientific poll. Could you give me a year range, approximate mileage and approximate average cost of the turbo jobs you've done? I'm trying to get a sense of the repairs that are happening on newer (10 years old or less) buses. I'll likely post a new topic too.
Thanks |

| I can give you a tally of our VGT replacement if it helps I took over here a year ago and we have had 5 total out of our 40 unit fleet go bad we don't have the time to take them apart so we just swap them out they cost us around 1700.00 each and about 2 1/2 hours to swap |
How did you get the gosinta in the whatchamacallit |

| That's what I was after. Thanks for the information. So, you're saying you have 40 that have that turbo? If so, a little over 10% failure rate doesn't sound too awful to me. |

Non warranty, we have replaced 11 out of roughly 100 buses.
We have also had several replaced under warranty. I cannot tell how many. We have roughly 300 buses currently under warranty with this turbo. |

Wow! I'll bet it gets hectic around there if you have a recurring issue due to a poor design. |

Yep. We were looking at getting 650 buses in here at one time over two days to do a 15 minute mod on our GPS units and there was talk about getting the highway patrol to shut down an exit on our downtown loop for the bus backup. They were talking about ten 2-man crews pulling two 10-hour days, having to pay 650 drivers for their time, plus what we'd have to pay to the HP and DOT for the interstate closure. We ended up waiting and doing it during summer maintenance. |

OH MY GOODNESS!! I love hearing these stories! lol Because of the awesome country we live in. But mostly, it reminds me how much I like living where I do with only 17 units to take care of. I have a pretty big job with all the hats I wear but I don't have a headache like that under those hats. At least any headaches I can't take care of. lol Thanks for sharing! |
