T3 rebuild guide?

[ejenner]

Anyone got a -good- guide to rebuild a T3 turbo?

[brownie]

apparently swedish dynamics gives you one when you buy their rebuild kit.

They are pretty simple to rebuild. Check for cracks in the core/water/oil bearing housing. Then get a stepped gapped/360° oil seal. This can be tricky to get set into the turbine side of the shaft and also set into the bearing housing/core. If you have all the parts, it should only take about 1-2 hours to rebuild a T3. I found the hardest part was clocking turbo and getting the oil return pipe to fit from turbo to block.

If you are going to rebuild may I suggest porting the compressor outlet. You can hog out a whole bunch of aluminum from that conduit.

Emmett, I'll see if i can find the guide i used, was for T25, but is similar enough.


First off you need to remove the turbine housing, then somehow lock it in place, i think i used a bearing pusher, with it locked you can then undo the nut on the compressor side (first get a blade and cut a grove into the end of the shaft and then onto the compressor wheel so when you put it back on you can realign it to the same place to keep the balance) then you need to use the pusher again to push the comp wheel off the shaft, that's about it then, just need to remove the roller bearings which are held in by circlips.

If you find 2 split washers, a large one and a small one could you let me know where you find the small one as i had one in both kits i got but did'nt find one when i dismantled the turbo .

It managed to come out of the hole in the block when I did my HG the other month - I got it manually as far in as possible, the tapped it in with a screwdriver - no sign of a leak since.

That was without the manifold in place, however, so the turbo was free to move. I left it in the car whilst doing the HG, attached (and supported) only by oil & water pipes.

Here's a guide with some pictures.
