I'm about to replace my OEM exhaust with a 4' and I am going to clean my turbo at the same time....I bought the billet unison ring and a turbo install kit and have it in hand, is there anything else I'll need to do this? barring any unforeseen problems when I open the turbo up that is.
That should be plenty. Soak the y-pipe to exhaust manifold bolts with a good penetrating fluid prior so that they're easy to remove, although you MIGHT want to have a spare set on hand if they're too rusty in case you break one.

Ahhhh, I hadn't thought of that, so you say the Y pipe has to be removed from the exhaust to R&R the turbo also? If so this could be a bigger PITA than I want to tackle, I don't have any exhaust leaks at the moment and am not looking to add any if you know what I mean.

Not removed, but loosened at the EGR cooler and y-pipe to manifolds sure makes it easier to get the y-pipe lined back up, at least for me. There are folks that don't. I believe they leave the turbo mount bolts loose while attaching the y-pipe at the back of the turbo.

OK, understand now Thanks, I'll soak them in the event that I do need to loosen them.....I've never done anything to this engine really except change the oil and fuel/air filters and clean the boost tube so this is all greek to me. But I have spent plenty of time here and you guys have covered about everything at some point so I feel like I can do a lot of my own wrenching when the time comes. Thanks again for the help.
Here's a couple of tips. You can remove the turbo without removing the alternator but if it's your first time I would remove it. It's only four bolts and it gives you more room to work with. Spray your three turbo mount bolts down a day or two before. I had one strip off on me and I had to cut the bolt head off. Not fun. And watch the oil pressure sender and wiring pigtail when you are pulling the turbo out. I damaged mine the last time I had my turbo out. It's one of those jobs if it was just sitting in front of you with no cab on I think a guy could R-R the turbo in about 15mins. Just take your time and be patient it will come out. Good luck.

Thanks, I'm ready to make a weekend of cleaning the turbo and installing the new 4" exhaust so I have time to do it right. I all so will have my son helping me (he's a heavy equipment mechanic) so I have an extra set of hands and someone that's used to dealing with the frustration that comes along with repair work.
On late models with the rear bolt turned vertical I use a1/4" drive ratchet that measures just under 5" in total length. Lay across the top of the engine and bear hug the turbo with a hand around each side to pull/push on the bolt. Easier if you've already removed the down pipe, so if you're cutting it out do that first.
Also the marmon clamp on the y-pipe, make sure the nut faces OUT when you reinstall. If the truck has really NEVER been touched it'll be a minor pain to take loose because it'll be facing the firewall. Check out the third .pdf (xNewSuperduty) for an explanation of that on page 5-6. I also bought a half-moon wrench based on the recommendation from that guide and think it's the best way to get the y-pipe/up-pipe bolts loose and tight, pages 7-9.

Thanks, all good useful info, I believe I have a pretty good understanding now of what to expect. My son is really great at wrenching just not familiar with the 6.0.....I'm about to change that
Another thing I like to do is take a couple old heavy coats or even a old couch pillow and lay it across the grill/rad area. Much easier to lay ontop of than trying to crouch down. Also I like to take a tool box or something up with me to set all my tools in while I'm laying there.
I rebuilt my turbo and put 4 in. exhaust in last summer. When your ready to put things back together get the up pipe pushed up in place before you put the turbo back in. Once you get the turbo set in place fasten the y pipe then the exhaust then tighten the turbo bolts. Not that hard of a job if you take your time. I never would have even attempted the turbo work if it weren't for this site. I sure have learned alot from these guys. I can still see the look on my dad's face when I told him I was going to pull it, split it, grind on it, then put it back together and expected it to work better! Which it did, my unison ring was fraze solid. Mines an 03, and it sounds awesome when the vanes cycle while it's idling.
