Cleaning turbo

What exactly needs to come apart (what are you guys cleaning) for keeping the vanes moving freely. The intake side or exhaust side?

The exhaust side of the turbocharger




I cleaned the unison ring with 400 grit sanding cloth and cleaned the housing and vanes with a brass brush. in this shot the vanes are closed. Make sure to put at least two refrence marks on the case and
be careful when you open the case that you don't end up with a pile of vanes and a unison ring in your lap. I was lucky enough to find good enough pic's on here to show me what direction to point the vanes.
I tried and I'm pretty sure you can't install the unison ring upside down. The result was a turbo that is much more responsive than before. There was very little rust on the unison ring, but the case under the vanes had quite a bit of rust and pitting.





Vanes in the open position.

What you use to clean the turbo is up to you. You can scrub it by hand , use a Dremel tool or die grinder with rol-loc disks or wire wheels.

you cannot flip it over (the vanes guides will be at the wrong angle), but you can put it in the wrong location relative to the VGT solenoid. That is why you need to match mark the housings including where the solenoid is.

Study the photos above and that should show you how it goes together. Note the blue dot I put next to the notch,and the location of the VGT solenoid as the vanes open and close that's why I posted both photos.
If you try to put it together one vane off The cam on the VGT solenoid will not line up. I am not sure it will go together. Once you get it apart you will see what I mean.


Cheers
