Is it possible to disassemble the stock turbo while its still in the truck? I am wondering if its possible to remove just the compressor housing.
Thanks.
Thanks.

Sorry...should have included this....
If it is possible, how does a person go about it? Is it simply disconnecting the I/C hose and intake, then unbolting the housing from the center section?

There is, but Im not sure if I'd then have to disconnect the oil feed and return lines, not to mention the coolant lines. Dont need to pull the entire cartridge out, just the housing.

Tom you still want that extra turbo i have? There are bolts all around, that hold the comp cover on- it will be a real bitch to try to get just the cover off. Would be easier to just take the whole turbo out than risking dinging up the compressor wheel
There are 3 major components:
Compressor cover
Centersection (aka CHRA)
Turbine housing
Any of them can be removed independently. It's actually common to pull the compressor and CHRA as a unit leaving just turbine housing in place. Since when a turbo blows up, the turbine housing is often still OK, you can save time by not removing it.

I thought I had one for $150, but looks like that fell thru. The guy hasnt answered in a few days. I've asked one other member at the Place about his today, so Im waiting on his answer. Im going to Holland tomorrow and am going to see if there's anything on the shelf. If not, it looks like you and I will be doing business.
My dilemma is this, read me the riot act if you think I am wrong, or nuts, or just plain stupid.....
I am planning on doing that port-n-polish and coating of the stock turbo. Trouble is, I also cant have my truck down for two weeks (plus shipping time) while its being done. I was going to find a second turbo and swap compressors, as I know what condition mine is in, and I figure using the 2nd one is a crap shoot unless its a low-mileage unit only run stock.
I figure as Pat just stated, the turbines dont get hurt as easily as the compressors, so I can use the second turbine. I'll get the parts back, and do the entire swap over a weekend.
Yeah, its complicated. Yeah, I know I do things the hard way. But its the only way I can keep the truck on the road while getting the work done, and also keeping "my" charger for any later tests.

Tom,
If you need a comp cover to send out I can send you my stocker cover if you will just send me yours back when you get done. My turbo has zero shaft play.
PM me if interested

Just a couple pics for people who have not seen a turbo taken apart
So this is the turbo. Off of a C-13 CAT Industrial Engine
This is the cartride when it is removed from the turbo Notice the clamps to remove the compressor housing and exhaust housings.
The compressor wheel removed. Note:This was LEFT HAND THREAD on the compressor end.
The cartridge with the exhaust removed.
The cartridges are rebuildable but it is much easier to just replace the whole cartridge if available. As you can see everything comes apart quite easily.

I ended up putting a new cartridge in it and putting it back on the unit. There was some wear on the compressor side of the housing but not bad enough to require replacing the entire turbo.
It has a T6 flange on it-not the most ideal set-up for our trucks
But yeah-4" inlet and a 5" outlet would make for a one nice big turbo!

That would be a perfect turbo to twin with your stocker
Was able to take a very close look at an LB7 turbo yesterday. Vaz is right. It would not be easy to remove the compressor cover. 6 bolts on the backside of it, with the bottom bolt located behind the oil drain tube. What is it with Isuzu and locating bolts behind other items? It woudl be easier to undo the Vband at the exhaust housing, but then you'd still have to undo the oil and coolant lines....not a fun task.
As for finding a turbo.......I now have that covered. Eric lent me a low mileage unit that looks almost brand new. Thanks for the offers, guys.
