What torque wrench is needed for rebuild?
 

I bought a 3/8 drive torque wrench that does 10lbs-75lbs/ft.

I realize this is the wrong one to have.

What wrench can do it all?

Or what 2 should i have.

that ought to do it....

NO IT WILL NOT.
You forgot the many small fasteners that torque to about 90inch pounds.
They hold the oil pan, TB elbow, ISC and AWS soleniod, crank pulley, oil pump, and others on.

Then also get a 1/2" one that goes to about 150ftlbs for suspension, drive train, and wheels.

What about the 300ft lb flywheel nut?

The only fasteners that are critical on a rebuild are the tension bolts...
So the torque wrench you have is fine.
In fact, since 30 lb.-ft is right in the middle of the adjustment, it's perfect.

Almost everything else use common sense, or I like to use the German standards "fukintite" or "titenuf". :)

bingo

Ted, I'm more a fan of the "old school" teutonic torque standard: guttentite!

As for the flywheel Q, you'd have to spend some serious money for the right torque wrench. Before I bought my "Jesus Nut" Snap-on torque wrench, I just use to do the simple math of putting my full weight (210) 18" out on my 1/2" breaker bar... bingo, 315 ft-lbs of torque (as long as the breaker bar was parallel to the deck at Q peak).

The flywheel nut uses sealant on it's mating surface with the flywheel / counterweight AND thread sealant (I use red Loctite) on the threads with the e-shaft.
Done properly, you don't need to hit the exact torque spec.

I've used everything from an electric impact 1/2"-drive wrench rated at only 260 lb.-ft to a 1"-drive pneumatic impact wrench rated at 500 lb-ft.
None of them had the flywheel fall off.

I don't know all the sizes, but I can tell you beyond a shadow of a doubt that you WILL need a 1/2" drive torque wrench.

Harbor Freight Tools sells a 300 ft-lb torque wrench (clicker style) for $70.

Be careful of the cheaper torque wrenches. The knob on the bottom (as pictured on the Harbor Freight site) will loosen as you torque bolts. So you need to make sure its tight so you don't over torque a bolt. I have one of the those (not from Harbor Freight, but its basically the same one) and it cost me a shock because of that.

If there is any tool to really spend your money on, its a good torque wrench. Most of the other stuff won't really matter going a little cheap on. Lastly, if you are breaking tools, you are using the wrong tool for the job.

To the original poster, I have;

* 3/8 torque wrench up to about 80 ft/lbs
* 1/2 torque wrench up to about 200 ft/lbs

Anything over that, I just smack it with an impact gun. The smaller bolts (less than 20 ft/lbs) I use the "guttentite" method. ;) Just don't go He-Man on the little bolts and you'll be fine.

Good point. Yeah.....I caught that too as I was using it.

Skeery...

I had a Craftsman torque wrench fall apart on me.
Now I own all Snap-On torque wrenches.
This is one tool I don't fuck around with.

Bingo!! I only have four Snap-on tools, and two of them are torque wrenches (a 3/8" and a 1/2").

Additionally, I've bought minor HB tools before, but found they have an uncanny ability to fail on weekend nights when replacements are not readily available... so what's you productivity worth?!

Sheeeettt...if I had bank like some of you guys I'd be buying Snap-On everything just as well. No offense by unfortunately not all of us are bajillionaires and can afford to spend big money on tools....especially ones we will probably only use once every 3-5 years (300 ft-lb torque wrench). :)

To tell you the truth, Craftsman Professional is about as extravagant as I get, and I don't even buy those from Sears...
eBay!
I bought all my Snap-On torque wrenches from eBay.
For a 1/2"-drive one, I can get it right around $100 - $120; that's like half price from new.
3/8"-drive ones are usually under $100.
I do send them to the local Snap-On dealer / truck to get them calibrated - real important!

I honestly only use my 1/2" torque wrench for wheels.
Then a Snap on 3/8" that goes to 100Nm for important shit, like engine bolts etc..
