Re: Uhhhhh.....This CAN'T Be Right...
If it were a junkyard turbo for $100 I'd giggle and rip it. However, it's a BRAND NEW turbo that I spent more than $100 for and don't want something that's already broke.
From specs they say radial play has to be < .03 and I have <.003 and that's at the most because you have to divide that (because when it's centered it's that much play on each side so that's only <.0015. Well, compare that to spec annnnnnnnd that's miniscule.
Most of you have calmed me down and I think I'm going to run it and it is indeed fine. I read on the little Garrett installation card about if the turbo is a T04/T04B (what I mentioned about being tight from a rebuild) the wheel may feel tight or not spin at all.
They say that is normal so I assume all diesel T04B's (even like what I had and saw was very tight) are tight. So does that mean all T04E's are generally a little looser?
Like David and TurboZexCRXMan said, it should tighten itself up with the presence of oil.
After I put the feeler gauges and saw that <.03 is spec for shaft play and I have <.0015 from center to max play I'm more at ease.
Thanks a ton guys, I guess I'll rock it, but I'm sure you can all imagine my anxiety of opening up a box with a nice new turbo and the shaft shakes its tail feather.
Last thing.....the oil feed is like 1/4" not standard 1/8". What's up with that? I plan on getting a bushing that fits in it then fit my 1/16" restricted 1/8" fitting into it and run it that way. Sound savvy?
Thanks again fellas. I needed the reassurance, big time.

You rocked (cuz I know you love that word) a brand new 48/60 and it came with shaft play? Whatever happened to NO shaft play?
EDIT: From installation instructions: "T04 and T04B turbochargers may have a slight drag before running-in, which is a normal condition." I guess T04E is in that category, even though I have no drag I have play which could cause it I suppose...

Re: Uhhhhh.....This CAN'T Be Right...
Well, I got it all on and running, but I have to have a 4-Bolt DP flange made at the shop for me tomorrow because I had a 5-Bolt, drilled it out to a 4-Bolt and apparently the existing 3 holes weren't in the right place to make it happen. So flange then marking DP and having the shop weld that up as well.
After all the concern of the shaft I even forgot to check it after I ran the car to see the condition. Duhhh....but I'm sure as you all say it's fine.
One more question fellas:
My oil return is 3/4" clear braided tubing and I drilled the PCV out because it seems I have crankcase pressure that on the deceleration of the car it starts to flow back towards the turbo a little. Never to the point of coming even near going back into the center section, but it gurgles back an inch or so and it's strange. Lots of crankcase pressure? This one has me a little stumped. I'm expecting a puff of blue smoke in between WOT gear shifts due to it "gurgling" back up further, but I could be speculating too much.
Any thoughts on that matter?
