Separating the charger
Remove the 4 bolts
the 2 rings will then come off this is what they look like
Spray a bunch of the best penetrating oil you can find around the connection of the Exhaust Housing and the Compressor Housing and wait for it to penetrate.
You do not want to separate the two parts violently there is a fragile shaft that runs the length of the turbo and connects the compressor wheel and the exhaust turbine
Bend it and you’re done for !
Here it is coming apart
Apart picks below:
Here’s the exhaust turbine
Now that its apart take the 16 Cm housing and slide it on over the exhaust turbine
Set one of the rings in place
You will only use the center hole of the 3 grouped together on the rings
Put each ring on and put the middle bolt in to hold the rings while your putting the other 2 bolts in
The ends of the rings have arcs cut in them and when both rings are on that’s where the bolt goes like so
Reference picture only
Leave the bolts hand tight
