Turbo removal

I'm having to strip off the aluminium half of my turbo so I can get to the bolt under it holding it onto the exhaust manifold but I'm a little stuck. I've removed the small 8mm nut at this end



I was expecting to be able to pull the wheel out but nothing is moving at all

Just to confirm. The 10mm nut at this end is just to hold the wheel still while I remove the 8mm nut and does not come off?



Any tips on how to proceed?

Stop undoing stuff first of all.(could get very expensive if you don't know what you are doing)
Why are you stripping the turbo down to remove it from the manifold?
Is it broken?
Is it the nut in the second picture? If so spray it with penetrating fluid and use the proper spanner for the job.

If you loosen all the turbo / manifold attachment nuts/bolts as far as you can, can you not then split the joint between the turbo and manifold? If you then keep a gap between both you should be able to keep undoing the bolts as the gap gets bigger until it separates?

You do not need to remove the turbo fan, just the large circlip as that is all that holds to alloy housing on, google clocking a turbo.
Dont #### it up as gen def turbos are **** loads of money!

Ah, I just noticed the circlip which googling, will get that removed next week as stuck at work for the rest of the week.

The reason I'm removing it as I can't get this nut off the manifold that's holding it on.





After a week of trying I've finally founded the nut and need to try and get a smaller socket on it.

Buy or borrow a Dremmel type multi tool and carefully cut into one or two of the flat faces on the nut, don't cut into the stud and it should become easy to remove by hand if not cut into another flat and it should just fall off.

Try not to snap the studs as they are a total cock to drill out, I gave up and bribed bloke at work with 20 fags to do it for me!

Split the nut with a nice sharp cold chisel.

Its so small it will end up damaging the stud.

Not if you use a small chisel.

He will spend all his time chasing it around the workbench, I only did this same job a few days ago, they are an arse and have probably been on there for 20 odd years

I did start looking at Dremel's and they are a nifty bit of kit, I was looking at the Dremel 4000

If you can get a nut splitter tool on it,use one of these instead? Cheap and they work without interfering with the threads.

The trouble with a dremel is the cutting disc is round so cannot cut all the way down the nut without cutting into stud and flange. Using a grinding attachement you still get to the point where you will grind the threads
With a cold chisel the nut will often start turning before split as the force distorts the nut and it can then be removed.

With a cold chisel would I just hit it on the side of the nut or is there a special way to use it.

you can get small nut splitters, work well.. looks like it would fit

You cant get a std ring spanner over the remains of the but, never mind a splitter

Bought myself a set of these, will be arriving tomorrow

Will let you know how it goes, that's if I can get them on without dismantling the turbo.

The nut splitter just ripped that bolt apart

Excellent
