Me thinks some turbos get up as high as 300,000 RPMs. At that speed ANY inbalance will result in catostrophic failure.

Me thinks it will be a bit more involved than just trying to reposition it correctly.

Dam I should have marked it hope there is a ridge on the shaft or something.

Anyone got any idea of how fast a turbo actually spins in relation to engine revs?

If you look at the compressor nut you took off, and look at the compressor wheel and turbine wheel, you will notice they have little bits of material grinded ( removed) from them.
What are the chances you can get the nut back in the same position?
At the speed it all spins, balancing is a big thing

Do you mean balancing it when its all put back togeather?
If so I didnt know you had to!
The compressor wheel is a press fit there couldnt be too much adjustment i dont think and the shaft sits in the two bearings in the main body so its pretty streight.
Anyone else know anything about this.

Now that you have taken the compressor wheel off the shaft, how do you plan on balancing the rotating mass once reassembled?

And not all turbos have circlips.

Yeah soaked it in wd before i posted.

Just needed a hit with the hammer.
You need to take the nut off the compressor side fan thing cause the whole shaft comes out with the housing.
No circlip just this other bolt on brace thing which the bolts were a pain to undo but good old wd40 came to the rescue there too.

Im maybe going to fix the oil seal in the exhaust side but now I dont know how to seperate the exhaust fan thing off the main shaft Any advice would be cool.

Thanks heaps so far.

2 people and 3 screwdrivers get the circlip off easy. one bloke uses his 2 screw drivers at the end of the clip flexing it and as soon as you see the clip coming up and theres a gap between the clip and it's hole that it sits in, the second person sticks his screwdriver in the hole therefore stopping it from falling back in, then you just manipulate the screwdrivers to get the clip off.

I hope I made sense


cheers
Damo

if there is a circlip, ud wanna hope u have access to some f u k i n big circlip pliers coz the circlip is huge !!! the guy that built my turbo manifold snapped his trying to take mine off. the pliers i used were about a foot and a half long !!!

if u want to remove the turbo u can remove it from the join at the exhaust manifold .....but if u want to remove the actual exhaust housing from ur turbo....there will deffinately be a circlip...a very large one then after that it will require a lrage tap....this thing heats up to 1 million degrees then cools to nothin like everyday the bastard will be on there very well believe me particularly if it is an old turbo.....as for the exhaust wheel it should be sweet where it is
