see i took the manifold off with the turbo, put the new turbo on, attached everything else, did a 4 time look over with my dad, started it, idled for about 5 minutes, took off down the road and next thing i know i was pooring white smoke out my exhaust. got back took it off the next day and realized i seperated my exhaust wheel from the shaft, dont know if I did something wrong or what.

Yeah im curious how you got the turbo off the mani without taking the whole thing off.
a couple weeks ago enrout to the fire dept i came up to an intersection, let off to clear it got back on it and realized i was rollin white smoke. then a few days ago blew it up. replaced it with a 62/71 and blew it up. im cursed i SWEAR.

used a half inch long handle rachet adapted down to 3/8 and a real long extension from underneath to get the down faceing nuts off. remaved the oil lines and the down pipe took off the upward facing nuts with a long handled wrench. from there i dropped the turbo downand let it rest on the frame. then i came up from the bottom and removed the metal oil drain tube. then i fished the turbo out from the top. then reverse the order to get is back in. i put the drain pipe in then pulled it up to the manifold and hand tightened the upward facing nuts to let it hang thenput everything except the exhaust and intake back on. tightedn every thin up reattached the down pipe and reinstalled the intake. removing the intake battery and battery tray helps make room to get in there better to get it out. it would have been easier going back together to have a second set of hands to help hold the turbo in place to get the nuts started. hope this helps:thumbsup:

Mike, I don't think you did anything wrong on the install. I think the friction weld on the turbine let go... crappy aftermarket shaft

Might have to get creative removing the turbo. The stock ones sometimes don't have a lot of clearance when dropped down on the frame. Either remove the center cartridge and compressor housing from the exhaust housing or try and remove the manifold studs and see if that give enough space to work it out. Otherwise waterloo has pretty much covered it all.
Also, put some anti-sieze on the turbo bolts and pour some fresh oil into the turbo while slowly spinning the comp wheel before start up.
Post any questions as I'm sure many can chime in with answers

he's fully capable of swapping a turbo... he's already done it once... I sold him a rebuilt turbo that let go almost instantly, and I think he's affraid that he may have done something wrong, and I know that he didn't

I'm swapping the manifold and turbo all together. So is it easier to have the turbo bolted to the manifold and then set it in the truck or put the manifold on first and then bolt the turbo up. BTW what tq should the manifold bolts be torqued too?

Wo I don't think anyone said or implied he wasnt capable. He came on wanting other peoples thoughts so why not give him as much help as possible? I doubt he's the only one on here with the same question. There's no such thing as too much information right?

Sorry to high Jack "again" but since we are on the subject of turbo/manifold swaps what torque are y'all torquing these bolts that hold the manifold on the block. Im capable but just need that little bit of info....somebody...anybody...Bueller...Bueller...Bueller...

I'll have to check and see if my wrench has that spec. :hehe: now when I fill the center of the turbo with oil do I need to fill the tube as well or will the oil pressure flow oil to the line? Sorry for being a high jacker but you've asked the questions I was gonna ask...

really, any good turbo shop will leave assembly lube oil on the shaft/bearings... it's always a good idea to pre-lube the turbo, but if you've ever watched a mechanical oil pressure gauge connected to one of these turbos, there's really no need to pre-lube a turbo if your engine is in good shape
