ct26 turbo seal help

[styx1787]

i recently took my ct26 apart. after taking the aluminum compression housing off and the compressor wheel. underneath that was a snap ring and an aluminum spacer (i guess its called the top bearing) and pressed inside the spacer is some sort of seal. the rubber part of the seal was hard, brittle, and broken. inside, and behind the rubber seal was a spring.

anyway, ive looked in alot of places for the name/numbers for the seal and havnt found anything. any help on where i could buy one would be great.

That is what we call a carbon seal, and carbon seal style seal plate.

Do you have a way to re balance the assembly?

(Note, this is an IHI carbon seal pressed into a front seal plate)

how far off balance can it be? if it was balanced when new.? I rebuilt mine and now im doing the GF's

^Huge. Ive seen turbos run for less than 5 minutes be so far off balance the turbo would destroy itself.

how do you rebalance the turbo?

 

[HommerSimpson]

well i got 2000 miles on mine ... and no problems.. but i still dont see how a turbo can be that far out of balance if its the same stuff going back in sept seals and bearings.. You will have to clue me in on how they can become unbalanced

thanks greg

It won't take much for something that can turn 100,000 RPMS.

MDC knows what he's talking about.

The difference between being in balance and out of balance is as much as...

THE CRAP THATS ON YOUR COMPRESSOR WHEEL FROM THE PCV SYSTEM AFTER 100,000 MILES.

Thats how little we're talking about here....

Yep. 100k rpm you will find out QUICK if your shop balances worth a damn
