Off topic about a Semi tractor turbo and blown motor

[sandman2234]

You have valid points. Your record you mentioned puts you in that 1% of 1%. I have an interview at Maine Motor Transport, you're one of the guys I mention in the first paragraph.



"Glory"? Yeah, maybe a smidgen, but they also put me on the right course for a profitable career and have given me a good resume if the need for it arises. Being chosen for this interview will come in handy for that fact alone.

Congradulations on the win, and on being chosen for the interview. Both make a impressive mark on a resume, no doubt. I think it would be interesting to go watch one of the competitions, but taking that much time out of my busy schedule would be hard to do. Guess I need to slow down and smell the roses, lol.

Three wins, podium every year since 2002 or so.

They are the most boring thing know to man to watch. Just contact your state MTA a couple months before you state TDC date and sign up. It's only one day.

Took a different truck this afternoon, with an empty trailer, headed towards the tire shop about 3 miles away. Running down a 4 line, 45mph speed limit, slowed for a set of R/R tracks, and after crossing them, proceeded to speed back up to 45. Heard a pop, then a whirling noise, like a squirel cage blower dragging on its housing. Immediately turned the key off, clutch in, and coasted to a parking place. Checked everything under the hood, but had a sinking feeling that I had just lost another turbo. Called the boss, and they called a Tech, who listened to it, then pulled the intake side of the turbo. Then we called a tow truck. I called the wife, who was on her way home, and she took me to get another truck. Boss said he had already heard about my second turbo from his boss and his boss's boss.
I don't know what I "might" be doing wrong, other than spending way too much time in those trucks, but two turbos in a month, after never having had one go before is a little scary. I have my ideas about what is going on, but really would like to know if anyone has any idea as to what could be happening. To the best of my knowledge, there really isn't much a driver can do to make a turbo go out on a truck, but if there is, I would like to know what it is, so I don't do it.

don't know what you could be doing to cuase this unless you were pulling a hill with a heavy load in the old days you had to watch the Pyrometer but if these are newer trucks you shouldn't have much of a problem...

I think its just bad luck. As you know I am a pilot and have been with my current company for 12 years as of November. I will go 5 years and no issues then in one month have 2-3 items break on the Jet that cost 1/4 of a million to fix. Its just the way it goes.

I once had 3 windows break in a month time period. 3 days down time each and about $25,000 each plus labor gets pricey real quick.

Its just the way these things work.

What is "going on" is statistics - sometimes known as coincidence, happenstance, luck, distributions, etc.
That someone can live to 80+ years and never find a 4 leaf clover, THEN find seven of them in a single day may seem astounding, amazing, in some way meaningful - a "sign", whatever...
It just means that randomness (and entropy) is "like that".

OTOH, it COULD be an indicator that the maintenance at your place of work has some "opportunities for improvement" (-:

Many things put put stress on a turbo, that could be driver related, revving the motor then shutting it down.
Staring it with the throttle pushed.
Unless you are pulling hard to the top of a hill then shut it off, Coking is not a problem.
Other than that it is usually something mechanical that causes the problem something coming apart, going threw the turbo and jamming the turbine, and breaking the shaft.
There is also the problem with the compressor wheel nut on some will break off, or even back off.
When a turbo fails you have to be sure the drain is free flowing, no scrap jammed, and the oil feed is not restricted. The air filters have to be changed and every piece cleaned and wiped to be sure there is no particles left in the air intake or stuck into the piping and that is aluminum to. Pieces will weld them selves into the piping, get into connections and destroy the new turbo,
I have found turbo compressor pieces in the left hand air cleaner in a Peterbilt conventional. Plastic intakes when pieces are found under warranty, we replaced the piping. We also removed the CAC we use to replace them now you wash it out, always flow the opposite direction to the air then tap it on the floor to dislodge any pieces in them.

or it could have a Honeywell tag on it... thats the most direct way to a turbo failure!!!..

Have to add that turbo tag to my pretrip inspections...
