Has anyone here done a write-up on how to change the exhaust housing, with torque specs for everything (if any)? I'll be ordering my 12cm here soon and would like to know if I could do it myself or take it somewhere. Keep in mind I am a mechanic and have access to a fully equipped shop.

 

This is a little more than what you are looking for but give you an idea.

This is something else I got thanks to RSWORDS on how to do a rebuild.

I apologize, that second link was from "muskrat". The first info was from RSWORDS.

And I thank both of them greatly for their great supply of info.

 

Thanks, that help me out a lot!

 

One thing that seemed to work well for me is,(and it might sound gay) sitting on the floor and holding the turbo with your hands and putting your feet on the exhaust housing. Put preasure on it while a helper with a dead blow taps it off. I've done two this winter and both times, that's what I ended up doing and it works quite well.

 

With this guide we have a donor charger so Removal of the charger is not included Refer to the Charger Swap Guide for further information
Completion time: Less than 2 Hours
Here's a 16cm Holset Exhaust Housing


Here's the Exhaust Gasket

Here's the Oil Return Line Gasket

Here's the donor charger
This set up is a Holset HX35W with a Modified 21 Cm Exhaust Housing to fit the newer model Cummins that don't have the clamp style Connection to the down pipe

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

Here's the new set up HX35W With A 16 Cm Exhaust Housing
Put the charger on the truck using the Exhaust Gasket (BUBBLE OUT) and connect the charger to the Exhaust Manifold.
Spin the charger around to where the Intercooler line is perfectly lined up then tighten down all 4 bolts connecting the Exhaust Housing and the Compressor Housing
Finish putting the charger on and you're done
Refer to the Charger Swap Guide for further information

 

Is this in the sticky? It should be!

Great info! Just need torque specs and we're all set.

 

Well I'm now stuck with everything apart and the old housing not wanting to come off the turbo. I've been soaking it with the best oil we have available here at the shop and it hasn't budged.

 

What are you using PB Blaster ? Kano Kroil is the only way to go , You need a good penetrating oil . WD-40 Is not a good Penetrating oil

 

We use GM Rust Penetrant and Inhibitor here at the shop. We heated it (lightly) with the torch and have been trying to tap it lightly with a hammer, but it still hasn't moved. I also have a bad feeling I may need a new turbo

I took off the compressor housing and notice the compressor wheel has 2 large chunks missing...
