Quick, Are standard T3s carbon or dynamic seals?
 

Quick question, Are standard T3 turbos (garretts) like ford thunderbird turbos dynamic or carbon seals?

Re: Quick, Are standard T3s carbon or dynamic seals?
 

Bump this ---- up 7 months later for an answer!

I need to know if my turbo (60 trim T3 .48/.60) has a dynamic or carbon compressor seal. I need to know which it has so I can order the correct rebuild kit.

Anyone know which it has?

Or, does anyone know how I can find out?

Re: Quick, Are standard T3s carbon or dynamic seals?
 

my ford 60 trim had a dynamic but not sure if it was original or not

Re: Quick, Are standard T3s carbon or dynamic seals?
 

So, do I have to take it apart to find out?

Once I get it apart, what are the visual differences between a dynamic seal and a carbon seal?

I just want to make sure that I order the correct rebuild kit.

you have to take it apart to find out.
1. Dynamic Seal
2. Encapsulated Carbon Seal
3. Four-piece Carbon Seal

ahh pictures are worth a thousand words O0

Just what I was looking for!

I'm going to try to take that bitch apart tonight and see what I can find. We'll see what happens... :-\

Re: Quick, Are standard T3s carbon or dynamic seals?
 

Looks like I have a 4-piece carbon seal...

I started taking the turbo apart tonight, here's what my seal looks like:

I only found three pieces though, the thick black piece, the spring, and the flat washer type thing... It looks like there should also be another seal of some sort, it could have gone flying accross the garage when the seal released, I didn't know there was a spring behind it and it cought me by surprise!

Anyways, I know which kit to order now! Thanks!

Re: Quick, Are standard T3s carbon or dynamic seals?
 

Okay, I ordered the correct rebuild kit from turbocity.com and cleaned all the parts up really nice...

There really wasn't that much build up on the turbine or CHRA at all, everything looked pretty good and there were zero signs of coking.

I just have one question about the carbon seal that I am not sure about...

I am not sure about the order of the 4 pieces of the compressor seal and how they all fit together. Here's what the seal looked like when it was still in the back plate:

When I was taking it apart I took the first part of the seal off and here you can see what it looked like with the first part off:

Attachment 37882

Now, there is another flat washer type part and a spring under it. When I originally took the seal apart I didn't know the spring was there so it surprised me when it jumped out and I think one of the o-rings went flying.

So, when all was said and done these were the parts of the seal that I found:

But, you can see in this picture of the seal that there is an additional part to the seal that I must have lost when the spring jumped on me, it's labeled "E" in this picture:

Attachment 37884

So, here's my question!

**What order do the seal pieces go in?**

Starting from the backplate out here's the order I think they go in: E,B,C,A, and then D...

I know the order of A, B, and C, but I'm not sure where E fits into them.

I assume E was under C because I didn't see it when I orignally took A off.

So, does anyone know where E goes?

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?

Re: Quick, Are standard T3s carbon or dynamic seals?
 

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.

;D

Re: Quick, Are standard T3s carbon or dynamic seals?
 

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

Re: Quick, Are standard T3s carbon or dynamic seals?
 

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! O0
