How to Rebuild a Turbo - Part 2 of 2

Rebuilding a td05h 16g turbo. This process can be applied to many journal bearing turbochargers. :) It definitely comes in handy to know how to do this when you are in this type of hobby.

4/25/12: Small explanation on the balancing of the rotating assembly since I get so many comments regarding it. This particular turbocharger, td05h, has it's rotating assembly components balanced separately. This means each individual part (compressor wheel, turbine wheel/shaft) gets balanced separately. This allows for easy interchangeability of parts in case they need replacing. This is why I am able to install a td05 20g wheel on this turbo without having to balance the entire rotating assembly. THIS IS NOT THE CASE FOR ALL TURBOS OUT THERE. You need to research whether your specific turbo (if it's not td05h) was balanced as an assembly or "component balanced" like I explained above. I hope this information helps. Good luck in your projects. Stay boostin'

All you hypocrites need to step back and think. Mechanics are the crooks (believe me. I was one) or wait a minute maybe you all are the crooks???.  This guy is trying to help with a decent video. You all were interested enough to watch the whole thing. Now kill the help. Most of us gearheads won't wait long enough to let a turbo go bad and if it did we would change it for a bigger one or feel a satisfaction of rebuilding things ourselves. Get off this guy's ass!! He is just trying to help.

TurboTechnics who supply Garrett, IHI, KKK and other manufacturers of small high speed turbos, with the world's most advanced balancing machines quote - " for small hi speed turbos it is not possible to achieve an adequate level of balance to the components pre -assembly so it is necessary to balance the complete assembly (hi speed balancing 200k rpm)"  So

If kids this inexperienced are doing videos on subjects they have just started to "Get into".... I should REALLY start making "How-To" Videos... I think I'm missing the boat. I've been doing this as well as full engine rebuilds and repairs on Cycles, Cars, Trucks and everything in between for over 27yrs now... Maybe people would be interested in seeing how a Pro does things? Hmmm

ротор турбины проходит три степени балансировки!!!! 
1 - балансировка вала турбины и колеса компрессора отдельно друг от друга.
2 - балансировка ротора в сборе с пистоном и гайкой
3 - ДОбалансировка после сборки картриджа.
Можно проигнорировать добалансировку (3) на рабочих оборотах, но при  замене компрессорного колеса - балансировка при низких оборотах

YOU COULD HAVE DONE A BETTER JOB CLEANING YOU TURBO PARTS FIRST BRO--- DONT HALF ASS IIT!!

[dkillahster]

Thank you so much for these Videos. Not many people actually "TALK" during a rebuild. You went with EVERY detail possible. Thank you!

[estewar]

Great job man and in HD even. Very comprehensive and easy to understand. A++

[uThandaBantu]

Thanks for the great video. Can you tell me what torque wrench you used? I'm having a tough time finding one that does in-lb on left hand threads. Thanks!

[ovalwingnut]

Good Job! You R the "Turbo Whisperer".. BTW: It's 2023 now and we use copper wire, magnets and computers to accomplish the same thing. Just saying.

@AdiGeorgescu22 The brass thrust plate and small thrust collar can wear (I have a pic but it won't let me post it grr), this will present as in/out play of the rotating assembly. Compressor surge and/or too much boost can cause this sort of wear over time. The journal bearings also wear over time, especially if the car isn't serviced well and the oil is crap, this'll show as excessive side to side play. <1mm side to side is normal.

re petroleum jelly on o rings, would only use on the right o ring but always use Vaseline because it prevents o rings cripping and kingking up , also put it on radiatort pipes so you dont have issues in removing em

@RichRusso4218 in the part 1 of this Vid he mentions the 20G compressor came with a TD05 cover machined to suit. It's possible to machine a stock 16G cover out to suit a 20G too.

Fantastic!  Clear, easily stated, and I didn't have to watch a 2 hour clip or someone talking to their dog in the process.  Nicely done.  Thanks!  

[gabbermaikel]

but that is the same everywhere. There are people that think meat comes from a factory, they don't know that it used to be an animal first.

i wrecked an evo 16G after a failed reassembly. If you hear the whine of death you know its already too late. do not force the shaft in, it should slide in smoothly.. giggety . after have it rebalanced, if you can get it done. local turbo shops in my town do not offer this service, rather they will do the complete rebuild for 80% the cost of a new 16G. Now im running a small 16G no complaints

[pishta]

have you ever come across a cartridge that had the ID around the bearings worn out? I would assume brass on Iron would wear brass first. My Holset HX30 bearings were toast and there was 3mm of play on the compressor shaft on both sides. Have not taken bearings out yet as I dont have a circlip plier that is that small yet. Just dont want to buy a rebuild kit if the cartridge is wasted. Thanks.

[mustangjunkie]

truly depends on what the buyer wants to do. if it will never see extreme boost levels the RPM of the turbo will never be so high that if you mark the assembly prior to disassembly it will be ok. I just built a 20G like this one and did have it balanced as it is going to see 25 psi daily. I also built myself a 25G turbo and had that balanced as well as it will be seeing 25-30 psi as well.

Good videos my friend! I have a turbo that Im currently looking into checking out the internals, and I have the v-clamp off and I have tryed banging the exhaust side with a towel over it with a hammer and the thing wont budge. Plus the compressor side just has 5 bolts, and no retainer clip like yours, so Im not sure how that side comes off neither. I can see what looks like a red or orange seal in there. Got any ideas how to seperate the 2 sides? Thanks

[PYcHoMN]

Yes it does. The whole assembly is balanced after it is built in the factory. You want to get it balanced after you built one because the slightest vibration can shorten the life of your turbo. You get people who say you can mark the shaft, but they are so sensitive to vibration even the nut being out by a few mills can throw off the balance.

That said, I imagine most people who rebuild their own turbo won't keep it on for longer than a year without tinkering anyway so becomes less of an issue.

god bless you sir...i have learned something new on how to rebuild a turbo thanks to your video....i have always wondering on how to renew and reintall the oil seals of the turbo...i have always thought that i would need a special tool to put back the ol eals on the turbo and yo just showed me that all we need is just to push them back in with no need for a special tool ...once again thank you sir for the free knowledge yo are posting on youtube..you are the best!!
