BNR Evo 16G -- too much shaft play?
Click to play the video. I think I know the answer already, but I just want to check.

Borked, son.

Would love to hear if anyone thinks differently, but I'll be contacting BNR... :spin:

your finger would have been enough to check for shaft play

Try holding the turbo still. It seems like too much movement to tell.

thefultonhow 04-16-2012 08:05 AM

I don't have three hands, man! :lol:

If other people think I need to keep the turbo more stationary in order to tell whether it's too much shaft play, I can get another video when my fiancee comes home, but for now this is all I have.

Why are you pulling on it with pliers? Seems like that's more force than necessary to check for shaft play...not sure though...?

It'd be nice if the turbo was still, but it still looks like the gap is changing between the fins and the wall.

So that my big fat hand wasn't blocking the light. :lol: I wasn't pulling super hard, but yes, I probably got a little more of a lever arm than if I were pulling with my fingers. Suffice it to say that there was a slightly, but only slightly, smaller amount of movement with my fingers.

I could be wrong but no movement is ideal. If you have more than a little...Like you said, contact BNR...

Good Luck.

Oh BAC5.2 is pretty good twith this type of thing too...

Sleeve bearings will have some play without oil pressure supporting them. That turbo looks like its got too much play.

Any thrust play?

You mean in/out? No, not that I could see.

Seems to have a bit more radial slop than is healthy but you look to be using a lot of force and the turbo is moving around a lot too. Can you get the blades to touch the housing or even within 0.5mm of touching?

thefultonhow 04-16-2012 10:15 AM

They're definitely getting within 0.5mm. Not sure if they're touching or not.

Get in touch with Bryan.
