Exhaust is going on Friday!

Updated to do list:
  • Finish split bench install
  • Intall locker cables
  • replace front driveshaft
  • replace/balance rear driveshaft
  • install Nation Luna dual battery kit (on the way)
  • wire in aux power outlets
  • install ARB (on the way)
  • install a winch
  • mount the RTT
  • repack rear hubs
  • change gear oils
  • find a spare tire
  • Hookup/Charge the A/C
  • build a cargo system
  • Clutch?

holy crap....

I hear you! My list is pretty long too. Good luck!

I feel your pain...... just finished up my list :cool: See you in New Mexico :cheers:
 
Awesome build and good luck.

I've got a 2H in my HJ that will soon receive a Safari turbo (without boost compensator though). Time is just not on my side.

That plan you made with the hand throttle is absolutely fabulous...mind if I copy it ;)
 
It's been a crazy couple weeks. I preparation for a continental divide trip I got the locker cables in, installed dual batteries with a National Luna isolator, mounted the RTT, borrowed back my old cargo drawers and was going to pick up a ARB and 8274 on the way out west. The truck was looking pretty good.

I was all packed up yesterday and on my way when I had a very unfortunate turn of events. I got about 30 miles from home and blew an oil line, the turbo feed line to be specific. The turbo is toast (lots of shaft play and ugly noises), hopefully rebuildable but I wont know until I pull it off. On the bright side, the 1HZ seams okay despite the brief loss of oil pressure. We'll see...

Needless to say, the continental divide trip has been postponed indefinitely and I am going to have to cancel the ARB and winch purchases and sell the RTT to raise some cash just to get the cruiser back on the road. Oh, and to add insult to injury the complete underside of the 60 is now black with oil. Awesome.

and if just one more person says I'm "lucky" because it happened so close to home.........:flipoff2:
 
What make is the turbo? A bearing kit usually isn't all that much $$$, just depends on if you hurt the turbine or impeller wheels or not. For all of their tight tolerances, turbo's themselves are not very complicated.

Doby at TurboPower was a real help in getting my 1600cc Ribbit's turbo set-up & then later rebuilt (I missed something important - no fault of his).

It's a Toyota CT26. I won't know until I get it off, but judging by the amount of shaft play and sounds it makes, I'm worried about the impellers...
 
ooh, isn't that really a Hitachi?

What I was told, and it was a long time ago, was that the cash for a bearing kit for an Hitachi would buy a whole Garret/AiResearch and be a better turbo to boot.
 
The "housing sub-assembly" (17021-58010) which appears to the entire impeller/bearing assembly is $1000 via toyota with member discount. Yikes.

I don't know who actually makes it, but it ain't cheap. I'm going to see what it'll cost through AAI. I'd consider a Garrett, but then I'd probably have to re-plumb everything if I do which would defeat the purchase of the kit in the first place...

*sigh*
 
Have you opened it up yet? Can usually pop off the compressor & turbine housings very simply. Check the vanes for damage & go from there.

FWIW: my work. No, they are not yet available to the public.

Nope, haven't had a chance yet. Hopefully this week...

VERY cool work BTW. Your company or are you an employee?
 
FWIW the bearing in the turbos that we base off of are held in place with small snap rings. A couple sockets, a torque wrench, and some snap ring pliers are all that it takes to replace the bearings on those. Ours is a bit more complex.....

Just a lowly employee.

Thanks, let me know if you need a test guinea pig...:cool:
 
horrible to hear about this gehn. when you called and told me this morning that just killed me.

sorry my cell dropped the call, i was 3 floors underground and surprised i got the call in the first place.


later buddy,

thanks rutbeer, but I've bought used and "rebuilt" turbos before and from my experience it's not worth the hassle!

I pulled the turbo yesterday. The good news is the hosing appears to be in good shape, though the compressor wheel does have some damage. A new balanced bearing assembly from AAI is a little under $700US and should make for an easy rebuild.

Hopefully the new rod bearing didn't run too dry. I guess I wont know until the cruiser is running again and can get it up to operating temp and can verify the oil pressure and listen for knock. We'll see. i may replace the bearings again anyway for piece of mind. For under $100 and a days work it might be worthwhile....

A note in the rebuild link says to "mark the compressor wheel and the nut before removal and to put them back exactly the same way." Implying that the comp wheel, nut, and turbine wheel & shaft are balanced as an assembled unit. I've not ever seen that done. While probably possible to do, it would be extremely ungainly and very much not something done in production.

The comp wheel is balanced by itself (to perfect or very nearly so), as is the turbine wheel & shaft (again to nearly perfect). Then they are assembled. Even at 120,000 rpm the amount that the nut can be off without being visibly off is so tiny that it is insignificant.

thanks for the tips. From the way it was described the bearing assembly I can order is the "CHRA" in that procedure which is the entire rotating assembly and comes assembled and balanced. Therefore, I assumed this means I can install it as such essentially just transferring the housings? I am going to wait to do the disassembly until the new parts arrive...
 
Since you're getting the whole center section, yeah, should be just plug it into your existing turbine and compressor scrolls and off you go. The only hiccup in the plan would be if your scrolls are different trims than the wheels on the new center section. If they spin freely inside the scrolls you're good to go!
