my turbo is a bit smokey so was gonna rebuild with new seals from garret with one of these kits that they do but a few people have said you have to get it balanced or it will be shagged in no time, so guys whats the score is it pretty vital?


cheers guys

 

they do about 120,000 rpm...

Do you think it wobbling a bit and then shatting the compressor wheel, which would send metal lumps into your engine is a good idea?

id never want to do a DIY on my turbo! i know it saves money but there are certain things i dont want to skimp on!

 

no need to be sarcastic mate just a simple yes you need to get it balanced would have done

 

But then you must ask yourself:
"If i replaced all parts of the rotating assembly exactly back as it was when i started, will the balance have changed at all anyway?"
Interesting question....

 

 

exactly stu. as i understand it, you just remove the compressor wheel from the shaft to change the seals and then put it back on at the same angle and nothing should go out of balance.

i read an article on the net somewhere that explained how to do all this. do a google search mate.

 

I read some where that most turbos do require a balance after a rebuild however with Garratt turbos you can get away with out balancing as they as Garrett balance each component of the shaft assembly independently so no matter how you put it back together it should still be in balance.

I'm not saying its gospal but worth looking into?

 

alot of conflicting arguements here


stu im gonna ignore your your comment even though its valid as its you im gonna be getting the repair kit off and you know it

 

Listen to stu...

What get balanced is the shaft n wheels, so how in fuck can changing the seals make it need re-balancing?

It neededing to be rebalanced is just more bullshit companys tell you to justify the prices they charge...

 

i rebuild my turbos myself , have done for a while , all the parts that come for my garret turbos are individually balanced anyway , its a bit like , taking a tyre off the rim , as long as it goes back in the same place nothing will change !!

 

out of curioscity, how accurate do you have to be on re-assemble?

if the thing was say 1mm out would it feck stuff? or have you got a bit to play with?

ive never dismantled a turbo or anytihng, just always wondered....

or can they only go back together one way, so you cant get it sightly off?

 

Jim dont try it

 

agreed

 

well i ordered the repair kit earlier from motorsport developments so ill let you know how it goes, if it all goes pop you know it needs to be balanced

 

Let me know how hard it is mate! Any chance of a picture of the kit and what needs changing?!

Cheers matey.

p.

 

there ya go matey thats the kit

 

the hardest bit is actually splitting the housings , after 80,000 miles of the warm up , cool down cycle things tend to become a little tight !!
