5 Ton Lug Nut Torque

[ke5eua]

If you can check the fit on the rear of the M923A2 that would be great.... I'm looking at a unit with a 1:58 gear ratio with 4800 N-m (3540 Ft-lb) max output - I'm guessing that should do it. The main body looks like it is 3.0" - 3.5" in diameter which should fit OK.

That's the one I have, I have no issues with it.

Well I think that's a problem you need to talk to your wife about.

You're married... what do you expect?

Back to the topic at hand and not wanting to talk about ya'lls personal problems...

I have seen the Swench manual impact wrench in operation and I swear by it. They are currently marketed under the Power Hawk name, I believe they were originally a Curtiss-Wright Tools product. They come in several models, 625-50 (500 ft-lbs), 750 (800 ft-lbs), and higher than that too. I was told there is nothing on the deuce and 5-ton series of trucks that would require more than a 800 ft-lb unit, even if the lug nuts were heavily torqued on and rusted there for years. Just a thumbs-up for that product....

Thanks for your input everyone... I've been checking out all my options... I was even at my local Rural King over the weekend and they had a nice 1" air impact wrench for $160 that I almost bought...

I'll probably just order one of those Chinese torque multiplier wrenches for $55 shipped. For what I will use it for, the price is hard to beat. Maybe I'll even paint it green to match the hoist and bottle jack.

I finally broke down and ordered one of those torque multipliers. I got a slightly bigger set so it will have the sizes for my 1 ton pickups as well.

So I received my torque multiplier wrench this week and tried it out yesterday. I didn't have time to change the tire but I did want to see if I could break the lug nut loose with this new toy.

Here is a quick review... I may submit a more detailed review once I change the tire with it...

1) I ordered the unit on a Sunday, it shipped on Monday, and I received it on Wednesday.

2) Before I bought the tool, I was concerned about the interference between the tool body and the rear hub pushing the tool sideways during use. The tool body does indeed touch the hub but not enough to cause major problems. The tool looks mostly perpendicular to the lug nuts when viewed straight on. The tool body is 2.820" in diameter where it touches the hub. I did some math using a worst case diameter of the hub, 8.75" a bolt pattern diameter, 11.25", and came up with .16" interference, or a little over 1/8". A person using an impact wrench probably doesn't hold it that straight anyway.

3) It takes a little work to get the tool positioned over each lug nut and into the correct position. At first, I could only get it in position to react against the hub but I soon figured out how to get it to fit against an adjacent lug nut.

4) I had to lean on the the crank a little to get the nuts to move but they come loose with much less effort than using a breaker bar.

5) Overall, this is a great tool and I can't believe that I've never heard of them before now.

Make sure to remember about which nuts are left hand thread and which are right hand thread. With this tool you'll get no warning about the correct rotation. It'll just snap the studs.

Just received this .....Mountain 16600 Torque Wrench - 3/4" Dr., 100-600 Ft/lbs.
Tried on 1 nut worked nice.

I have half of my lug nuts torqued exactly to specs. The other half are my best guess, based on the feel of the correctly torqued ones. I have yet to see a left handed torque wrench that registers 450 ft/lbs. I have a right handed one that's on loan from a very good friend.

Here is mine that just came in the mail. 46 inch one inch drive beam type and reversible directions. 200 to 600 lb.ft.

I have the same break down wrench - been using it on ship engines for 2 years now, Precision makes nice stuff - I also got the extendable breaker bar and a 1" drive head to go along with the 3/4" head...

They also set me up with a spare spud that goes between the head and the first extension or breaker so it can live in the 1" head and everything can be swapped around as needed...

Being able to torque in both directions is a requirement in the heavy marine diesel world too

I got one of the 1:78 torque multipliers off of Amazon, not a bad tool for $85, but kind of cheap. Mine had a few tight spots so I worked the tool quite a bit and put some wear into it until it smoothed out (for proper torque readings). I just did mine by hand while watching a few movies, but a drill would work nicely with the right adapters. Then I pulled out the plug on the input shaft on mine (came loose on it's own), drilled and tapped ot, then put a grease fitting on it, welded it back on and filled it up. Read a review of people taking them apart for the same purpose but the snap ring is pretty stout so I'm glad I got it modified for future maintenance.

Has anyone tried one of these style torque multipliers on their MV? I was about to order one soon and was wondering if it works in both directions so a lower poundage torque wrench could be used since I dont have a large impact or air yet.

I just bought one I'll let you know

I use a Snap On 36” 1/2” drive breaker bar. Keep it on truck with the 1 1/2” 1/2” drive impact socket. When I’m leaning on that thing they are goodentight. At least I know I can get them off on a dark highway.

Torque multipliers are sent form heaven.

I’ll bet after 7 years he already figured it out
