- In this video, I disassemble the stock GT3788VA turbo and rebuild it using a Spoologic rebuild kit from ProSource Diesel!

Thanks for actually showing the fails with a broken bolt and non successful welding nut. These are the things people dont see or realize happen. Great video
Thanks Aaron. I agree, real life is a little different than the shows on TV where everything goes perfectly and it only takes 30 minutes! 😂
best video on youtube on how to do these duramax chargers ! youre awesome
Thanks! I don’t know about the best on CZcams but I’ll take it 👊
Great Looking LBZ BUILD BROTHER
Much appreciated Rex, can’t wait to hear it run!
Great video! I’m subscribed
Awesome! Thank you!
Yes, awesome vid on turbo rebuild…might just do mines!!👍🏽…Aloha 🤙🏽
Thanks! Just remember to be careful with the up-pipe to turbo manifold bolts. Definitely don’t want to snap one off like I did!
Commenting for support!
Thanks Jason!
WTH! 😝 Great videos
Thank you for this video. My 2006 is at 165,000 and giving the typical codes. I’m trying to psyche myself up to pull the turbo out and do this. I know it needs it. Mine still has an intact EGR.
You’re welcome! Be careful with those up-pipe to turbo pedestal bolts. They are normally very stuck and will snap if you get too aggressive with them!
Great Video. Is the little arm that moves the unison ring supposed to be hard to move by hand?
Ty
You’re welcome!
I'm interested in seeing your parts cleaning setup. Wow what a good job you did cleaning the turbocharger, something I need to do on my newly purchased LB7 engine...
Thanks! I’m not gonna lie, that took quite a bit of elbow grease to get it cleaned up! I cleaned the big iron parts in my harbor freight 20 gallon parts cleaner with some purple power degreaser and some stuff scrub brushes. For the aluminum parts and the center section, I used orange degreaser in a heated 8gal ultrasonic cleaner.
Great video, lbz owner have cleaned my egr out twice in 135k I know my turbo looks like that one. Thanks
Thanks! Yeah that egr system doesn’t do the turbo any favors for sure. Good on you for keeping it clean!
Does the plunger and gear sit in an oil stream during operation or does it require grease?
Yessir, the plunger and gear will be in the oil flow. It’s actually oil pressure that drives the plunger in and out!
How do you remove pin from plunger. The video didnt really show how you did it before cleaning parts.
Yeah I didn’t do a great job at capturing that part of the disassembly. You have to use a drift punch and hammer to drive out the pin. It is snug but doesn’t take that much force to get it out. Hope that helps!
Did you balance the turbo shaft after adding the new billet compressor wheel?
Nope, the rebuild kit I used came with a pre-balanced compressor wheel.
What size socket did you use on the back wheel to get the wheels apart
Man it’s been a minute since I did that rebuild but I think it was a 7/8 😬
What color VHT paint is that. Great video btw!
I want to say it is the VHT flame proof flat silver color.
I’m in the process of rebuilding my turbo off my lly…not sure how to get that pin out that holds the gear that moves the plunger lookin thing I can get it off the gear and push it out but it won’t go all the way through any tips?
You have to use a roll pin punch (or similar punch) to carefully drive that pin out to separate the gear and shaft that drives the unison ring. Once you get the pin mostly out, you should be able to remove the shaft then carefully drive the pin the rest of the way out of the gear.
@@richphippsgaragethank you i appreciate it there was a tad bit of runt on the end of the cylinder the plunger sits it a light touch with sand paper, slid right out but in the process of putting it together I broke the first tooth on that pinion gear and can’t seem to find a replacement one anymore…but thanks for the help I really appreciate it!
@@kaidentabor7009 ah I see, I didn’t realize you were talking about the plunger! Glad I could help and I’m sorry about the broken gear.. I’m sure you’ll find a replacement!
What was the cleaning solution you used in the ultrasonic cleaner?
I used the Zep orange citrus cleaner since it’s safe on aluminum but still pretty strong!

Ok sweet. I just bought an untrasonic cleaner. A 30 liter. At what ratio did you dilute it? I wanna do all the turbo housing parts. Hot side and cold side. Just wanna make sure i don't go overboard with it and.mayne damage something. Turbo was purchased used and it's in good condition but bought all new components anyway.
I put the whole gallon in there and filled the rest of the way with water so I think that comes out to a 1:7 ratio of cleaner to water
Did you put the whole center section in parts washer?
It was either the parts washer or ultrasonic cleaner, I can’t remember 😬. Either way, I used a mild water based degreaser to clean it up.
I'm doing this process now
Good luck!
Only 79 trips? That’s per hour, right?
yup that sounds about right 😂
