7.3 turbo exploded view
Does anybody have a exploded view of a turbo on a 7.3 ? It would make me feel a little better if I had something to look at. My compressor wheel, ex. turbine and shaft should be back today from getting balanced. I'd like to get it back together tonight. If its warm enough, 4-5 inches of snow last night.

Brandon did a good writup with pics. Check out the thread.
That exploded view, while similar, does not appear to be the same turbo as our stock trucks have.

Good write up. I read the whole thread and wondered why a screw driver was used to hold exaust wheel. I was wondering if thats were his whistle came from. In the picture below it looks like several fins are bent. Is that something to be concerned about ? I liked the warning about the thrust bearing, I could see it possible going on wrong, and burning up the turbo. I don't mean to bash about exaust fins, just wondering about it.

I think that is an optical illusion because of the angle. Look at all the blades from 6-11 o'clock. They seem to have the same bend that changes slightly with the angle. The ones from 12-5 do not appear to have it and I believe it is due to the angle.

That turbo is for a different frame. Have a look at the shape of the up pipe flange. Ours is the reverse rotation one IIANM. Those locking clips are not a part of the stock turbo either, though my BB unit has some similar clips.

It is an optical illusion. Chris rode around with me yesterday and he confirmed that the dentist drill has to go. I will tackle that this week.
The thing is, if you have pulled the drive wheel and shaft(1 piece) out of the housing you will realize that it weighs a lot and is a serious chunk of metal. To bend the blades on the exhaust side of the turbo would take alot of force, way more than a screwdriver wrapped in a towel could exert. remember your compressor wheel is only about 1 turn past finger tight (if that much).
Also if you'll notice that large gouge below the shaft in that pic of my drive wheel. well, that is how a wheel is balanced, material is removed until it spins true. if you look at the pics of my compressor wheel you'll notice a couple of chunks out of the backside of that wheel too.
