Is there a course I can do on rebuilding turbos?
Rite lads, I want to know if there is anywhere I could do a course on rebuilding turbos? I now this sounds like one of them wank questions from a twat but I am genuinley intrested in this. I am a fully qualified mechanic and am looking to further myself. So can anyone help me out? Also does anyone know where I would go about getting spare parts for turbos?
Cheers Lads!

you need a balancing machine that will spin in excess of 10,000 rpm, unless you have one or even access to one there aint much point

Too many posts.. I need a life!!
Noone has answered the guys question though, I'm afraid I can't help either, but does anyone know where he can learn to do it? even if he cant due to lack of equipment. Lots of people do welding courses but have no welder at home....
Yes more like 100k RPM, although today I'd say even this can be too low.
JAmes.

Cheers for the input lads. I must admit I had no idea of the cost of it but I would still like to do it. So so far it sounds like turbo technics are the fellas to talk to!

wrong, we run 13 caterpillars d8s and d6s all turboed diesels 8 to 14 litre engines and the guy who rebuilds them for us doesnt have balancing equipment and if they dont need a new shaft or comp wheel he rebuilds them in house. and we get 5 to 6 thousands hours from them. the d8s have a garret t66 i think.

so what you are saying is you don't need to balance a turbo that has been stripped based on your experiences of a turbo builder who doesn't have a balancer,on a huge turbo that rotates once a week lol
that is like saying you don't need to balance your wheels if you put the same tyre back on and only do 20 mph
Please don't give uniformed advice,it annoys me
the turbo's used on cars are substantially smaller and rotate at speeds from 80k rpm up to 250k rpm on the smaller ones such as a gt15
Like i said they must be balanced

How do you know you have it all back in EXACTLY lined up, inc the nut etc, not disturbed the balance by taking small metal shavings off the nut as you use a socket on it etc.... at 100,000 rpm a gramme can make a fucking big difference...

im not gonna argue but ur wrong they dont need balacing if only new bearings and seals. ive had a r5 gtt one done new bearings and seals and not balanced and worked fine at 12 psi so its not uninformed advice.

I think telling one of the most respected and knowledgable tuners on here (not to mention one of the ugliest), that he's wrong with regards to turbo's is not the smartest move...it makes you look....
well.....

FUCKING RETARD!

i have seen the turbos done big and small so i know it can be done. none of them have had to run 2 bar plus boost but theyve still work fine as standard. if it wasnt right then the turbo i took of last week that needs new seals wouldnt have lasted 6000 hrs.

BIY rocks
a question you should ask yourself is are you trying to encourage people to diy and should you be encouraging them.
turbo building is a specialist job
lets hope you don't get a brain tumour you will probably want to fix that yourself too roflol

It is an interesting topic turbo building. I have in the past upgraded a garret turbo with a bigger compressor wheel and housings without getting it balanced.
It was on a mates car and he was prepared to take the risk. It worked fine and was used hard for many miles with no problems.
All the components were genuine garret from the states.
I have heard in the past that all garret components come individually balanced to a tolerance garret find acceptable from the factory.
if this is true, with the accuracy of modern machining you may find you can rebuild a garrett with out balancing?
I suppose if all the components are balanced to a tolerance and you are unlucky enough in how you clock you parts you could end up with the cumalative of those tolerances.
As for the speed of the balancing machine, surely that is dictated by the sensativity of your measuring equipment.
I know the forces involved will be greater at higher rotational speed eg 120k but surely if your machine is accurate enough you can detect those forces at 10k?
I guess the forces developed by an out of balance shaft rise expodentaily with rpm so i guess life of a DIY tubo could be hugely rated to application and use?

Scabbyslayer: Likewise. But you really are making an arse out of yourself.
I once saw a man hit a window with a hammer and it didn't break.
Therefor glass doesn't break when you hit it with a hammer.
Seen it with my own eyes!

i rebuilt my turbo, with new bearings and seals, wasnt balanced. i took every precaution possibe to get it built perfectly.
lasted 1 week, thats 1 week before the vibration caused bearing failure at coombe and compressor wheel touched the housing.
its a mugs game risking not balancing them, and something i will never do again, the actual turbo strip and build is piss easy

PassionFord Post Whore!!
i've rebuilt about five turbos, took every precaution etc etc and only one fucked up, maybe now i know why and the other times i was just lucky!
again using garrat turbos.
