I heard of the term "shaft play" on ebay and on this site. But what is it?

 

when you stick your finger inside the air inlet of the turbo and move the turbine with your finger, the amout of play in the shaft is called shaft play.
so if you can move it up and down or in and out, thats shaft play and too much can be a problem and it can also be used to tell what kind of shape the turbo is in.

 

rofl this topic hit my funny bone. bwhahahhah

i play with my shaft..

 

is it true that turbo that dont uses ball bearings will have some sort of shaft play? This guys tries to sell me a T3 turbo. And he told me all that. Im not too sure about that. So i wanted to confirm with you guys first if what he saying is true?
