If you were starting from scratch with stock turbo under the hood, and had in your hand a new compressor assembly and new turbo housing where would you start first?


Should I dismantle the old turbo compressor side down beyond the backing plate while it’s still bolted to the manifold? I would assume that once that’s taken apart it will be easier to get at the exhaust housing? Fewer things in the way while trying to tap/pound/bang the housing off? Also since its bolted to the Cummins there is leverage to some degree when trying to loosen tough bolts.


I know there is some hammering involved and care taken not to damage any of the internal parts of the old housing, which will be replaced with the 16cm. It is only right that before pounding on this part to have the whole turbo off the manifold first. Seems only natural if one wants an even removal w/out binding.

So far I know that I need (for the compressor side)
12-point 3/4 socket
Breaker Bar or Ratchet
13 mm socket
7/16th wrench
8mm wrench
torque wrench (both way style)

This will be a first so I'm a bit nervous and want things to go as smooth as possible with out breaking good stuff in the process. Most of you have already gone through this and know the in's and out's. My truck is my only means of transportation.


Thanks very much for any help.

btw, the parts for this project should be coming in tomorrow (wednesday)

 

It doesn't matter too much when you do the compressor. Either way (on or off the truck) will be pretty easy.

For the exhaust housing, just be careful when pounding on the old housing not to hit anything you don't mean to hit . I would recommend having a torch, just in case you need to heat it to get it off. Make sure it comes off evenly and spin the shaft to make sure nothing binds up.

It's pretty simple once you get out there and start doing it.

 

I would take the whole turbo off the truck to work on it. Break the turbine housing bolts loose while the turbo is still bolted to the manifold. Do the compressor after you swap turbine housings. That way if you get too enthusiastic with the hammer you will only mess up your old compressor housing.

Don't try to knock the housing OFF. Just beat on the housing with a big hammer until you see that it has moved. Keep flipping the turbo and banging on the housing, checking for movement every couple of whacks. Once it moves, switch to a smaller hammer and gently tap the housing off while turning the shaft to make sure you are going straight.

 

Oh Yes, the Torch! Thanks for reminding me!

Will need a need can of fuel for that.

Auto parts store is 12 miles away. Adding heat has helped me in past projects.

Thanks wannadiesel for your help as well.

 

Torch and penetrating oil are your friend when taking off baked on exh housings. Mine was on so good I was tempted to get the oxy/acetylene torch out!

 

I stumbled onto a trick with PB Blaster that might help on exhaust housings. Had to fight a bleeder out of a wheel cylinder and it was frozen solid. Soaked it with PB Blaster for 2 days and still nothing doing. I was going to use the candle wax trick so I proceeded to gently heat the wheel cylinder before putting candle wax to it [just warm enough ro melt candle wax down into threades, not hot enough to burn up wax]. While heating I saw the PB Blaster start boiling and bubbling and then disappear down into the threads!! Quickly put the Vice Grips to the bleeder and it spun right out

It wasn't very hot when PB boiled so go easy.

 

Wow, haven't heard the parrifin/wax trick in a while, but it does work, but not fast. Penetrates well.

 

That's what worked on my housing - PB Blaster and a torch, after soaking overnight.
