ALL advertised numbers are BS. Put a torque wrench to a bolt or nut and watch the lies show up.

The ATT is on! And I blew an injector on the way home? OR, My weekend with Leroy :)

Does the air impact depends on the capacity of the compressor?

I was told the ATT's are made in China. Is this correct?

The psi determines the torque, impacts have a max. psi rating
IIRC they are, to Slim's specs.

Psi does determine the torque but you need a big enough compressor to keep up with the volume.

Sentinelist, IMO the hardest part of the whole thing is changing that darn seal in the front cover. 
I bought the proper install tool off ebay, so hopefully it will go much easier next time.
Leroy sold me a Fluidampr install kit. comes in a nice blow molded case, and has all needed adapters. with this kit (or one like it) installing the HB is a piece of cake.
As far as holding the crank, we take a pair of damper pulley bolts off a parts engine to use as a sacraficial part (keeping the 4 good ones for re-install.) and using some small pieces of pipe and some flatwashers, makes a nice setup to hook a prybar into. one guy running the big torque wrench from above, second guy holding the prybar underneath.
Call me old fashioned, but I dont care to use an impact on an engine. dis-assembly, maybe, but install, preferably not.
We have a 1/2 inch drive Harbor freight earthquake wrench. it will easily handle 200 lb/ft, havent figured out how much more. for the big stuff, we have an Ingersoll Rand 3/4 drive good for 1200? lb/ft maybe 1000, but it is pretty gutsy.

Well I figured out how to resolve this. In the interest of experience, fear, progress, and time once again, I'm going to just pay a man to help do it for me... Guess who? On the weekend after next? I'll get the replacement crank pulley put on beforehand, and have a brief respite on the home project front for the next couple weeks.
I'll also be getting the exhaust put on at the same time (clearing out the massive box that's been in my camper for a year now), and the trip will give me another test run opportunity with the rig that I still need to build further travel confidence. As the HB job isn't something I intend to regularly do for my future reference, it's worth what time I have to see that it's done right once. And that's thousands cheaper than a new engine anytime too soon.
Also, good impact wrench info!

Hmmm . . . Hear that this mechanic happens to have a shiny new motor in the shed. See if you can swap yours out while he is taking a break

That balancer sure would look good on a P400! Haha
Thanks for the warnings I'll be sure to chain down the P400 while he is here .
We have the 17th scheduled in. It should be fun!

Actually it would technically be: "Assembled in the USA with foreign and domestic components."
Made in China, further machine work done in USA, and some parts added to the kit in the USA. The turbo is biased *Cough Chinese copy of Cough * off a Japanese design. The turbo, unmodified, is used on heavy equipment and the ATT kit turbos are part of the bigger production runs for the other application.
The quality is the main variable that is under control with the ATT vs. the unknown ebay HX40II's that don't even have consistent blade counts.

Aren't most vehicles today 40% made out of USA. Parts shipped in then assembled in USA?
Some made in China parts are good, others bad. ATT has a good track record

Hey, what are the torque specs on the crank pulley bolts again? It's below freezing this weekend, not sure I'm going to get this on until perhaps Friday morning when it's back in the 50s (and I'm taking the day off).
Also, if anyone has a new or highly dependable and serviceable I'd-drive-this-cross-country crank pulley, I'd like another as a spare.
Only below freezing? That would be nice. It's been below ZERO all week here and we're looking forward to the 20s and maybe even 30 in a week.

Lol during the day here we are only in the 20s. Teens and single digits at night.
To the op, find yourself a new pulley for a spare. They are cheap enough rather then carrying a used one.

These are 35# of metal to haul around and don't leave you stranded when they do fail. The HB you don't want to fail, but, the belt drive is just noisy. They live for 30-100K. In fact most of mine reached 170K+ as I only recall replacing one on the 3 6.5's, but, replaced the HB several times. I recommend other spare parts you will need and use more like a lift pump, starter, alternator, and fuel filter.
If you haven't upgraded the POS firecracker alternator to a CS 144 - a good spare with the correct larger diesel pulley is good to have on hand - yes a tested spare as new ones can be dead out of the box. I have been places where they don't have them in stock and, sadly, I was the parts delivery for the area...
Hi all, I'm new on here. Just got on tonight to try and find some info on my TCC Locking and Unlocking going down grades. Very interesting thread on it. Then I saw this one and have to say that you All seem very knowledgeable in your own ways. Glad to see people still care about helping others. I happen to be a Field Service Mechanic and need help myself from time to time. As for the air impact, I use a snap on Pro. and only to tear down. Always hand tools when going back together. I got tired of drilling and tapping broken bolts out. I hope in the future I may be of some help here. Thanks to all of you.

Yeah yeah on you eskimos... I love being out in the cold weather, but not when I'm lying fairly still on the frozen concrete in it! Forget that. It's gotta be at least in the 40s. If I'm working and moving about, reasonable subzero temps are fine.
Good point- I wasn't stranded when my pulley went. It was just loud as hell near idle. I do carry a spare lift pump and fuel filter, but good call on the starter and alternator. The latter is on my list to get next, and I'll carry the current one as the spare.

Quick update- I phoned Leroy today and told him I needed to reschedule the visit. I just got under contract on a property this week and am finally getting some acreage. We close late February, and I now have a home to sell beforehand! Shouldn't be a problem in the market we have here currently, but there is a helluva lot of boxes and packing and storage unit schlepping and rushing projects to completion going on here. Before the baby arrives in May.
I'll check back in once my house is listed and I can breathe, briefly, for a bit again!
