[robertglines1]

My experience is that the hammer action of an impact wrench is needed to remove over-torqued nuts.  The smooth application of torque from a multiplier won't break them loose.  It is far more applicable to installing the nuts than breaking them loose.  I recommend a bigger impact gun and more air pressure.  When I first took my left hand thread nuts off, it took 140 psi on a Blue Point (Snap-On side brand) 1" drive gun.

I sheared the 3/4" drive on my torque multiplier clean off, that did for that idea, and that tool hit the float test.  Based on what I was doing, I expect that the thing failed at around 2000 lbs of torque.  Hammer torque works way better for taking nuts off...

Dallas. both right and left threads frozen(over torqued) have half of nuts off on both sides.guess I'll get one of the guys to run service truck by and loosen them..my gun hits 850 lbs and won't shake them....no big hurry..don't sound like torque ampflier will hold up..did you put them on???bus from Tods

the passanger side tag and drive came off OK...was looking for a long range solution to take overtorqued lug nuts off and loosen bolts..have no other reason to own a 1 inch impact..

I guess it depends on your torque multiplier.

There were some posts recently about nuts coming off with one that had a 1:58 multiplication.

That is a pretty hefty boost in torque, it has something like 7000 lb-ft limit as I remember.

My 12:1 says it is good for up to 3000lbs. It was spendy but i feel it was worth it. Takes them off and when you put them back on you know exactly what they are torqued to.  I had to buy all new wheels this winter, at least 2 were cracked. Tire shops are never going to touch my wheels again.

Robert, While you are hitting them with the impact take a 4 lb hammer and hit the side of the impact socket. It's not the easiest thing to do considering the weight of the impact and such but it works like a charm. You don't have to be bashful if it's a good socket. Put some impact tool oil or atf in the air inlet of the impact also.

Put some impact tool oil or atf in the air inlet of the impact also.

They call for a drop or two.  I gave mine a "squirt" before I used it once and it softened the blow so much I might as well have been using a drill.  Sparingly wins the race.  But I agree with you Chopper...some oil is needed or the tool chews itself up.  Don't ask!

My impact gun blows out the excess oil in short order. Makes a bit of a mess & the tool slippery.

My torque multiplier has a 1" output & is rated for 2200 ft lbs. I feel that rating is very conservative given the weight of the unit & it was military surplus bought off eBay.
I've not had a nut yet that it wouldn't remove - although, a couple had me thinking I was going to lift the bus.

If you get one, be sure it is rated to do what you need it to do.

I know I have a 1" air impact wrench and wouldn't take off lugs that the tire shop put on. I bought an electric 1" job made by makita and it would take the lugs loose so I carry the electric with me. Jerry

Ed,

I agree, no tire shop is going to tighten my lug nuts again.

Changing them all in a rear hub taught me a good lesson.

There is a great tool called a Swench. Its a manual impact ratchet. The 1" model that I have is heavy - 40 lbs. but it works good, I've used it to remove payloader lug nuts in the field that I could not move with a 5' pipe on a breaker bar. Google Swench -check it out. They cost way too much new, but used ones are not too bad.

I had one of my guys run a service truck by the bus garage and loosen them..will torque my own wheels from now on...we have the 1550's on service trucks and he said he had to hammer on one;was cross threaded...so wheels off and not as much damage as I suspected from fire..still some airlines (plastic) in tact and air valves for the most part look good .will have to replace some and will evaluate all...thanks for the come back on torque multiplier..Bob.
