Nice diagrams.. Where did you find those? I have been searching around for them all day.

In the first diagram, the one of the carbon seal, is #12 the spring?

So, if I'm reading this correctly, the correct order is B,C,E,A?

I found a diagram that shows how the parts of the seal are supposed to go together...



My kit should be here tomorrow which means I will have the turbo back together by this weekend.

Well, I guess I'll keep updating this thread eventhough I'm the only one posting in it. LoL..

Maybe someone will benefit from this info in the future.

So, I went ahead and put my turbo back together on Saturday afternoon. I cleaned everything up really well and put it back together with all of the new parts that came in the rebuild kit.

When I first put it back together the shaft seemed to be a little loose in the new bearings. It had a TON of shaft play...

So, I just took it back apart, and took the new bearings out and replaced them with the old bearings. My turbo had been rebuilt before I bought it so I think the shaft had been machined down a bit. It's fine though, the turbo had no shaft play before I took it apart and the bearings were in perfect shape anyways.

I put the new compressor seal and compressor wheel back on the turbo and gave it a spin. The wheels don't spin really freely but there is no shaft play in-and-out or up-and-down at all. The wheels do turn smoothly and there is no wheel to housing contact at all. I'm thinking the seals just need to be broken in, I remember it didn't spin freely when I bought it.

I should be putting it back on my car this next weekend! I'll keep you updated and we will see if it works or starts spewing oil, it should be interesting. I'm confident that it will work perfectly, I read countless turbo rebuilding tutorials and I'm sure I did it correctly.

Thanks for the help!

is it really hard to turn? you should be able to turn the wheels with your pinky finger... they just dont spin, but they should turn easy. If you have the nut on the compressor wheel too tight or if you installed the collar around the thrust washer upside down then itll be very hard to turn. The chamfered edge on the collar (looks like D in the above pict) should face the bearings in the centersection, the flat side should face the compressor housing

It's not that the wheel is hard to turn. But it doesn't keep spinning after you let go. I can totally turn the wheels with my pinky, it's not that they are bound up or anything. The do turn easily, but they just don't spin freely... kinda hard to explain, but I'm pretty sure it's normal for a freshly rebuilt turbo.

The nut on the compressor wheel is exactly where it was (in relation to the shaft) from before I took the turbo apart. And I made sure to install the thrust collar correctly with the chamfered edge towards the bearings.

I'm sure it's fine, I'm glad there is no shaft play and such... I just can't wait to put it back on my car and see if it works!

P.S. Sorry for totally hijacking your thread! I just didn't want to make a new one when our topics were so related.

**Update**

I put everything back on my car on Saturday morning.

After working out a few leaks it seems to be working fine. The shaft spins freely, and it builds boost fine. I only drove it for a mile or so on Saturday afternoon and then I drove it to work this morning (about 15 miles).

Everything seems great! No noticable smoke, noise, or leaks. The turbo even seems quiter than it was before I rebuilt it. It used to have more of a whining noise as it spooled up, now it's quiet but spools great.

Anyways, I am going to check it again for leaks today and make sure I have them all taken care of and then plug in the wideband to make sure I'm still tuned up.

Thanks to all those who helped me rebuild my turbo! Saved me a boat load of money!
