Hey Stone,

The swap looks great. Who would have thought by looking at it that the old 60 had such a gem under the bonent. Just 2 questions... 1) Have you found a suitable vessel and chain for the 3F-E boat anchor to be fitted to? 2) Has Sheldon found a buyer for the aftermarket air-conditioning from the 60?




It's getting pretty cold down here now, but I made the trip to sydney this weekend gone to pick up another BJ42.

cheers,

Mark.

Not holding my breath on a tach conversion for my 1HZ. Found this little guy that looks promising for the time being. Need to go measure my injection lines-

Tiny-Tach: Diesel Tachometers
 
Ducks: ...

And yes, I'm looking for a 12V stator coil...I know the one of my FJ80 compressor is the wrong size...perhaps the one from an FJ62 will be the right one.

According to the parts catalogue it does look like the stator for the fj62 is the same as the one for the HJ61.

Hi Mark:

It was great to meet you and your GF when you were over visiting Sheldon. I'm sure you didn't think you were going to be wrenching on Cruisers while you were on vacation, did you? :) I heard that you guys got that nasty cold that I was dealing with...sorry about that.

The boat anchor is still sitting in Sheldon's garage...we'd love to get rid of it to clear his floor space. I don't know about any aftermarket AC on that 60...I'm going to try and find a 12V stator coil from an FJ62, and if I can't find one locally, I guess I'll contact Dave in Japan.

Hope all's well with you guys...I'm still drooling remembering that awesome ute that you have. :beer:

I used the Tiny Tach in my 6.2 conversion. I bought it originally to use to calibrate the tach signal converter (which I never bought) then ended up just using the Tiny Tach. I attached it on the bottom left side of the factory tach (just stuck it on the plastic), it worked so well I never worried again about getting the factory tach working. It was a breeze to install, took all of about 15 minutes! Great tach for the price!

Thanks, Rusty...I'll keep the Tiny Tach in mind. My boost gauge and pyrometer are both Isspro, and I'm considering the Isspro diesel tach just to keep everything matching. If it doesn't work out, then I'll get the Tiny Tach.

I have a Land Cruiser single A pillar pod made by Autometer on order. I think I might mount my tach there.
 
The Dakota Digital converter was the route I was planning on going. After speaking to them they said I needed a tach to calibrate it. I did not have a tach that would work on a diesel so for the same price I ordered the Tiny Tach with the intention of using it to calibrate the Dakota Digital. I ended up selling the Cruiser before I got around to it.

So my saga continues with my turbo woes. Just to recap, I wanted to ceramic coat my turbo and exhaust manifold before I dropped the diesel into the FJ80, but I was afraid of damaging it so I took it in to ADP Distributors in Port Kells to have them takeit apart so I could take the parts to Kool Coat. The turbo was rebuilt by ADP approximately two years ago.

Sheldon had warned me about going to ADP because he had previously taken his 1HD-T turbo to them for a rebuild, and 2500 miles later the turbo spun a bearing and the vanes got all chewed up inside. To top it off, ADP tried to blame him for the issue by accusing him of "overboosting" even though Sheldon just ran his setup stock. ADP eventually warrantied and fixed his turbo, but not without some hassle. Apparently Ciaran has also had problems with them in the past.

I considered this, but because I see that many of the commercial truck guys take their turbos to be serviced at ADP, I thought that they can't be that bad. Also, Port Kells is much closer to me than B-D in Abbotsford.

After my turbo got put back together I noticed there was a bit of play on the shaft, so I took it back to them. The tech agreed that it could use a rebuild, and wanting my rig to be done right from the beginning, I thought I'd go ahead and get it done. When I asked why the original bearings lasted well over 15 years and the one they replaced them with lasted only two, and whether or not they were using good bearings...the answer I got was "bearings are bearings". Yeah right! As if metalurgy has nothing to do with it. :rolleyes: They blamed it on possible poor maintenance.

So paid my big bucks for the rebuild, and to be fair these guys treated me nicely throughout my other fiasco with Kool Coat, I was excited to install my turbo. As you guys have read, we did everything right and on the very first short run, oil was puking out of the boost side of the turbo. So...took it apart...AGAIN...and sent it in to see what happened.

Tech calls me back and blames me for the issue. He said that something went through and hit my turbine, knocked it out of balance, and that why oil was leaking out. I don't know much about turbos, so I took his word that that was the case. We really couldn't think of anything we had done that would have caused that damage...except for the welding and machining that ADP had just done to repair the flapper of my wastegate...but ADP maintains that their welding looked fine and that was not the issue (of course). When I told them I will take it to B-D if I have problems with warranty, they said this kind of damage is "cut and dry" and no turbo shop would warranty it. So...considering that this was the second time I've had my turbo in there, and I've already spent the money there, I thought I couldn't go elsewhere without spending big bucks again. Besides, since this is my second time, what are the chances that they would screw it up again...right? :rolleyes:

They replaced my turbine and didn't charge me anything for it...and this made me happy. They cleaned up the turbo and made it look nice, and spinning the shaft by hand it seemed nice and smooth. So, spent all afternoon installing it and sorting out the electrical issues I had after installing my stereo system. Fired it up using the proper procedures once again, and it fired up nicely. Idled it with no load for quite a while, topping up my coolant in the process. Finally thought I was ready to go, and excited to finally take the truck home...and would you believe it...I didn't get much further than just ouside of Sheldon's driveway! The turbo made the most hideous noise...a whine and a vibration above idle. And it was freaking loud! So rather than risk more damage to the turbo, I just parked the truck back at Sheldon's.

When my turbo had the supposed turbine damage that threw it out of balance, it DID NOT make this hideous sound. So I'm left wondering why all of a sudden they supposedly fixed my turbine and now it seems even more out of balance than before? I am frustrated beyond belief, and I've finally conceded that I've possibly lost all the money I've spent at ADP because there's no way in hell I'm taking it back there, even if they warranty it because I have absolutely no conifdence that they have the capability of doing it right. Besides, I'm tired of re-and-re'ing this turbo and I haven't been able to spend much time with my family because of this. I'm taking it next week to B-D to hopefully finally get it done right. THis is the only thing holding me up now.

Moral of the long story (sorry) is it's hard to find good help these days, even if I'm supposedly paying good money for professionals to do it.

I'll see if this video upload works...video of the turbo whine soon after install...

All I can is :censor:. This really, really sucks, hopefully B-D gains better results. I'd be interested in hearing their prognoses, if there is any. And as usual, you want something done right (like a 12H-T into an 80) you do it yourself, maybe with a bit of help from Sheldon :lol:. Anything outsourced you are at the mercy of the tech/shop.

This sounds very familiar, when I got my 6.2 conversion finished I needed to have the 700R4 set up and an exhaust system run. I found a shop that did both transmissions and exhaust so that seemed perfect. They had my Land Cruiser several weeks the first time just for a simple exhaust system and transmission set-up. I finally got it back and the transmission went out about 100 miles later! I took it back to them for the same reason you did (I had already paid them for it) Turns out it was my fault it went out, I didn't get the output shaft pushed all the way in to the pump so it didn't have enough fluid pumping. it took them about a month to rebuild the transmission but I finally got it back, after this it still wasn't right and finally it quit again after about 200 miles! Again I took it to them! This time it was their fault so about another month down the road I got it back again. It still wasn't right so I finally took it to another shop, paid them and got it back the next day and it was perfect!
Wish I had done that in the first place, in the long run you won't regret it!

Stone ... I'm really sorry about your story .. that sound too familiar to me if you ask to me .. but I live in a 3rd world country and It can be more posible ..

One of the reasons to try make all my jobs by myself ...

I hope you can get a nice turbo job now or why not a good used CT26
 
Rusty...what you're saying is exactly what I'm thinking now. I'm sick of ripping out and installing the turbo, and if I keep taking it back to these guys, who knows how many more times I'll have to repeat the process and in the meanwhile, how many weeks until I finally get this truck on the road? I guess to these guys my time is not worth anything.

Tapage...my CT26 is fine, and in fact it has a brand new cartridge. Really all I need is someone with some skills and the integrity to set it up correctly. Besides, not very easy to find a good used CT26 for a 12H-T around here. Just seems like the more times ADP handle my turbo the worse it's getting, so I'll cut my losses and have some real techs look at it at B-D.

Phil...Sheldon can't seem to get rid of my junk from his shop...LOL. Poor guy...:beer:
 
Hi Stone,

If you can find a low km jap import Turbo from a Toyota 7MGTE, buy that, change over the exhaust housing and you actually have a better flowing turbo than before (slightly bigger trim compressor). I have at leats 4 CT26's in my shed. very basic turbo to rebuild and should last 300,000 miles. If you dissassemble, buy a rebuild kit of eBay for $80 and get a shop to balance the shaft and compressor wheel, you should be good to go - wouldnt be hard for you considering all the other tech you have done!

I bought two Supra CT26 (off the 7MGTE) of eBay a while back for only USD 220/ea. When I disassembled them I found them to be like new.


In case it helps....

Thanks...I'll keep that in mind in case it comes to that.

I bit the bullet, considered all the money I spent at ADP to be lost and a lesson learned, and dropped off my turbo at B-D in Abbotsford. They immediately found a large crack and hole in the exhaust side of my hot housing. The crack is directly behind the repair of my wastegate flapper that ADP had done. Looks like the sleeve they inerted may have cause enough pressure to extend the crack and cause a sizable hole to appear.

Don't know what else is wrong with it...the ceramic coating somehow was removed when the housing was washed in Varsol. ADP did offer to pay for ceramic coating of that part...but for the sake of time, I think I'll just pay to have B-D send it out for coating. I may need a replacement housing anyway. Also, oil no longer leaks from the boost side...but it now leaks out the end at the exhaust side! Unbelievable!

Anyway, hope B-D can have it fixed for me fairly quickly.
 
What an incredible build. Sorry to hear about the turbo issues though. Hopefully that won't sour what sounds to be a great experiance.
 
Gbentink: I picked up my 7MG-TE turbo from B-D today! :bounce2: Fully refurbished...just need to clock it properly so that the oil and water ports line up with where the 12H-T needs it to be. I can't wait to see what the bigger trim will do. Thanks for the tip...:beer:

So here's what's wrong with my old turbo...or what messed it up according to B-D:
Vibrations were a direct result of a stock compressor wheel being installed on a machined turbine wheel stem. Appears shaft was machined for a performance wheel and not measured prior to being used.

When the nut is loosened at the compressor end of the shaft, the compressor wheel wobbles like crazy on the shaft. Obviously the final machined tolerances were waaaaaaaay off.

There were lots and lots of grinding/machining marks on the back of both my compressor wheel and turbine...I was told this was evidence of them trying to balance something that will never balance.

The brand new bearings were already scored...before starting up my engine it was filled with brand new 15W40 diesel oil and a new Napa/WIX filter. Because everything else in the engine was clean, I'm going to lean towards crap being left behind from the machining process in the turbo itself.

Anyway...that's it so far...

Trust me, once he starts driving it everything will quickly fade into a distant memory. Whatever you have to go through it is worth it once you are behind the wheel of your own creation!

Ducks: Thanks for reminding me to ask Dave S. regarding my stator coil...I've ordered it from him today. :beer:

Newly remanufactured 7MGT-E turbo is going into the engine tomorrow...wish me luck. I'm kind of jaded by the whole thing, so hopefully this is the last time I crawl under my truck and get doused in Toyota red while installing a turbo. Thanks to Gbentink for the tip. :beer:
