Are chunks like this taken out of the compressor wheels of turbos to help with balancing?



This 14b was unusable so I went out on a limb and got another. The new one is in damn good condition (one teeny tiny crack in the wastegate. no light can get through it), but it too has chunks like that taken out of the wheel. If it's perfectly normal, please tell me, so I avoid bitching out DA-MAX.

 

:edit:

o those chunks... thats probably not supposed to be like that

 

Between the compressor blade and the center section.

 

yeah thats normal. every company does it differently

 

yup, most Garrett t3s have those too.

 

wow...i didnt know that they did that. I just thought they were damaged.

 

Wow thanks guys. I'm feeling a little better about this now. There's also a little piece missing around the center section above the seal but below the snapring. I'm not too worried about it since it wasn't visible before disassembly (it was under the snapring) and the seal itself doesn't appear burned or compromised in any way.
