Need help with turbo repair.

[EZFEED]

Hey guys I need a little help with my turbo. I'm planning on rebuilding it in the near future and would like to know if anyone sels a rebuild/repair kit/individual parts for these with all necessary gakets and bearings. Are there any special tools that I'll need?
I'm not one of those guys who brings stuff to the shop to have a "professional" do it, I prefer to do it on my own so this is a shoutout to all of my fellow do it yourselfers/home mechanics.

Memphis has kits for about $280 if I remember correctly. If the case has been rubbed by the vanes, throw the turbo away, it will be out of balance. I took apart a C turbo to rebuild, found nothing salvageable. Shaft was scored, one end of the ceter section was spun out, and the compressor had been nibbling on the housing. Gave the remains to Freight Train to mock up on a Ford truck.

Yea,and that turbo is still rolling around in my trucks bed.....One day I will get it out and see if it will even bolt up to the Turbo system I have in the shed....

Is there a TM or other reference out there with instructions for disassembly, inspection, replacement of damaged/worn parts and reassembly of a "C" or "D" turbo?

I'd like to know the same as Lee too.
Surley the turbo isn't a "disposable" part that cannot be serviced.

I have the turbo manual at the house, but I don't have it scanned yet. Turbo's are rebuildable, but from what I understand, the military just swaps center sections.

RDM is correct. Only Depot rebuilt turbos. At the unit level, it's a "repair by replacement" type of part.

to build a turbo correctly is must be balanced and I dont think anybody here other than maybe ken has that equipment. have a turbo shop do it unless you want more problems down the road.

The manual you are looking for is TM 9-2990-201-40&P. It dosn't cover all the turbos but enough to get you going. Portrayal Press sells them.
I've rebuilt a couple myself. No problems so far. Parts may be hard to find and expensive. Schwitzer (Borg-Warner) had kits for the "D" (3LM) turbo a year ago when I got mine. I think it was $125.00 from a local dealer. Good Luck!

I have that TM. I need to scan it and get it uploaded into the tech section.

Make sure when you take it apart that you mark the shaft and compressor wheel. To make sure you put them back in the same exact location as you took it apart. If not it will be out of balence. Turbos this small have to be in balence with in just a few milligrams. IF not they destroy the shaft and bearings from vibration. This takes only a couple of seconds. The worst case is a pretty good compressor wheel explosion! Witch i'll get some pics of.
