GVR-4 Rebuild TD05 16G problem

[galant_martin]

Hello

i just bought an turbo and had to replace the compressor wheel, turbine wheel &shaft and the bearings. Bought all parts balanced and used the old locknut, I used lube to assembly it but now if i press on the any of both wheels i can feel it moves in/out. Very minimal but i can feel it. i have no feeler gauges, i would say its not even an half millimeter or 0,02". It has minimal lateral shaft play but i read its normal without oil pressure.

I never rebuild a turbo befor so i dont know, is that normal or did i anything wrong?

Thank's

Did you replace the thrust collar/plate and bearing or just the shaft bearings?

Everything is new.

Then it sounds like an incorrectly machined turbine shaft or thrust part. Take it apart and assemble the thrust parts to the wheels/shaft and see how much play there is.

I noticed a thing while I assembled it. If I put the turbine shaft in, the thick part of the shaft comes out a little bit of the bearing under the thrust spacer. So the thrust spacer doesn’t lay flat on the brass bearing. If I insert the thrust plate and press it flat in the Char the shaft goes out a little bit.

I forgot to make pictures but I try to make them today. It was late yesterday..

Can you actually put pics and maybe a video link?? like record it and upload it to youtube and after we see and possibly get a solution you can delete it. Just a thought, i rebuilt my turbo and literally had no play other than turning. i would take it apart and look up a youtube video called how to rebuild a turbo and type td05 and dude does a pretty good job doing the job and explaining. here is the link:
