I searched and searched, came up with only a few results, lot of people have said that a very small amount of shaft play is normal. what defines a small amount though?

I just picked up a turbonetics/garrett hybrid, from what i am told, its a turbonetics 60-1, with a garrett t04e compressor housing. .63 ar, 57 trim. Zero miles, it was rebuilt by a local shop in NJ (think it was called MJ turbo or something along those lines) anyways, the blades spin freely, they make no noise at all, but there is maybe 1mm or less of shaft play, Is this normal for a freshly rebuilt turbo? I'm just looking for reassurance i guess. It's obvious the turbo has never been ran since the rebuild.

When I first got it, I checked for play, and felt nothing, then I clocked the turbo, and noticed it had a wee bit of play, its minimal, but enough to bother me since I don't have alot of experience with a new/rebuilt turbo, I don't know if this is normal or not.

I read somewhere it was bad to spin a turbo if it is dry and has no oil, but I had already spinned it at this point. I was thinking maybe if I had some oil in the center section, it would feel better? Tighten up the feeling I guess?

Anyways, long story short, Is this normal? Maybe I did something wrong? I'm just looking for opinions from someone who may know, because I don't really know. Thanks.

 

90% of the time it is normal. Remember, the bearing system uses oil as not only a lubricant but it also helps balance the shaft during spinning. Don't forget, these speeds are in excess of 98,000rpms, so the fluid helps "center" the shaft and compressor wheel.

Don't force it so that it Makes shaft play, that is not a good idea. As long as there is no shaft play in & out, there should be no problem.

sounds to me like that's just a normal t3/t4e 57trim .63 a/r. Because a 60-1 is much larger than a .57 trim!

Awesome, this is pretty much exactly what I wanted to hear, I figured with oil it would feel how I was expecting it to.
