KO3 Turbo Rebuild - In Depth Instruction
HTML-код
- Опубликовано: 25 авг 2024
- This is an in-depth teardown and rebuild of the KO3 turbocharger for folks of all skill levels.
This guide would work for KO3s of all kinds.
This particular KO3 is from an Volkswagen AHU TDI, and is suffering from an oil leak. However, the KO3 turbo can be found in many VW and Audi cars

Update: This turbo has been installed and run for about 1000 miles with no issue.
Amazing video. I rebuilt mine without any issues. Thanks again for putting in all the hard work to make our job easier.
No worries, I’m glad you found it helpful.
Love almost everything about this video. I do want to say that it is important that you position the open part of the turbine retaining ring, the snap ring that the journal bearing sits on and the compressor backing plate snap ring upwards or against gravity if your center cartridge won't be perfectly upright.
If you don't you'll have oil leaks through the small crevice into your housings
Good to know. I’ll keep it in mind for next time
Great video, my ko3 on my mk5 gti is leaking bad but this video explains everything I needed to know to rebuild mine, thank you man👍👍
Appreciate it, glad it was helpful.
What rebuild kit did you purchase?
You don't have to match or align turbine to impeller. They can be purchased separately for that reason. The balancing of each component is done in the manufacturing. To make it clear, it's like a tire: it gets balanced to itself, not to the other wheel on the other side.
Makes sense to me. I suspected when I rebuilt the Garett and had to replace the turbine.
Thanks for your input. Must have just been some old piece of info I heard a long time ago. No harm in being careful though.
@@haoleboyshow-tos2279True...never hurts to be careful. Thanks for your video, I needed to see the torque of that nut and it helped.
thanks for sharing this!! i decided to rebuild mine k04 0028/0029 and your video showed me the way. one question, my kit has 2 journal bearing, like yours. one with a big oil hole and the other with a small one. but on my turbo, it came with the small one. can i just replace it with the one with the big hole, checking orientation of course. thanks in advance
Thanks, I appreciate it. I would use the smaller hole bearing if that’s what matches the old hardware. Best of luck!
I forgot to mark the compressor turbine wheel. It has marks that show it's been previously balanced. Is there anything I can do without taking for a rebalance?
Someone mentioned in the comments that they are individually balanced. I haven’t been able to verify, but you won’t need to worry about alignment if true.
So, no gasket, no o-ring, or anaerobic sealant on the compressor housing flange??? My 2014 Audi Q5 had a gray sealant. Super thin layer. I was hoping you would use it and tell what to use.
Use RTV copper, that seals well and isn’t temperature sensitive.
Really useful video! Question, where did you get the parts diagram and torque specs? I'm looking to rebuild a K04. Also, what parts would have needed assembly lube during reassembly?
Just google image search “K03 turbo and exploded view”. Torque specs are mostly standard given thread and material. I would lube the points where the turbine shaft touches the bearings
thanks for the explanation, i have a question , i wanna know if the ko3 rebuild kit is the same for the ko3S ?
@@sadness3out961 I am not familiar with the K03s it appears to be the same, but I can’t say for sure.
@@haoleboyshow-tos2279 thank you for the answer is the ko3s that you rebuilt still working well after all that time ?
@@sadness3out961 Yes, it is still working from what I know, but I don’t own the car anymore. I put about 3000 miles on it before selling
Is it possible to replace the waste gate? Mine is loose and rattling.
Sure, I actually did replace mine in this build. The original was full of oil. The difficulty will be in finding one. You’ll probably need to find it on a used turbo.
@@haoleboyshow-tos2279 thank you. I will probably need to replace the actual flap and the mechanism that connects to the actuator rod.
I can't get my chra back into the exhaust housing. It's like it's an extremely tight fit and I don't want to force it too much and bend the blades
It is a pretty tight fit. You may have to put the compressor back on, cover the inlet with something and tap it on with a rubber mallet. I did something like that in my video on the Garrett T3.
@haoleboyshow-tos2279 I ended up heating the turbine housing with a propane torch and it slipped in almost perfectly!
Question is it the same turbo on the vw jetta 2013 1.4L tsi single charge ?
Not sure what that uses, but it won’t be a KO3.
Where did u get the fit from?
I used this kit.

@@haoleboyshow-tos2279 I have a k03-006 turbo for my ahu tdi I think I'm gonna rebuild it or get a cartridge.
@@infernoking7504 Good luck. The rebuild is easy and cheap enough. I’d recommend that route.
Any chance you have tried a water pump?
I have done a water pump for the AHU engine before I was filming things. Try looking up how to do a timing belt. That will get you most of the way.
do you have a link to the rebuild kit?

Dang thats a little mini turbo..So my 2001 beetle glx 1.8t has a K03S turbo.. probably the same size
It’s pretty tiny, but it fits. Going larger than a KO4 on these and they get laggy quick
@@haoleboyshow-tos2279 I will say this..for this turbo to be so little it does pack a punch..spools up quick..KO3 S turbo is just a little different..
14:09 i laughed. thank you
Any chance you know where I can find the ko3 bearings and gaskets rebuild kit

@@haoleboyshow-tos2279 and I’m assuming it hasn’t stopped working or anything yet, you wouldn’t have chose a different kit if you could go back? Just trying to be certain tired of waiting for parts and having shit torn to pieces
@@eliwalker8410 Everything worked just fine, I have no complaints with the kit.
I since sold the car, but I put about 3000 miles on the turbo with no issue.
@@haoleboyshow-tos2279 alrighty thank you I appreciate you greatly man
