    There are a lot of threads about these at Garage Journal site:garagejournal.com torque multiplier - Bing

    In the attached article, I suspect that the poster could have used a better quality (ie more expensive) 3/4" breaker bar and gotten similar results. Tekton is not top of the line ... It would be interesting to see if a SnapOn 1/2" breaker bar broke in the same place as HF and Craftsman.

    I'm a mechanic by trade and purchased one 20+ years ago when working on big trucks. Maybe used it twice. As Tim said, a quality 3/4 breaker bar would have done the job. I wouldn't buy one if it was only for home use.

    We use torque multipliers all the time at work, I torque really really big bolts to levels nearing ridiculous.. They work great, but for average daily use, if a big ol breaker bar don't get it, it's time for the fire ax..

    He should have hit with an impact gun. I've used my 1/2 HF earthquake to break those loose. If not that, then my buddies 3/4 IR gun.

    The multiple shocks work better.

    I carry a Two and four foot piece of pipe in my service van for stubborn oil pan drain bolts on semis and class 8 type trucks. One time I had my 3/4 breaker with a 36mm on a drain bolt with the four foot cheater for a large caterpillar motor and I didn't think it was going to come but it did.

    I have also used an 7 foot piece of pipe as a cheater bar for my subaru motor crank bolt.

    In the above case I wonder if quality 3/4 drive and pipe would have done it? That one might have needed the torque multiplier.

    Archimedes said it best, "give me a lever long enough and a fulcrum on which to place it, and I shall move the world"

    One of my most favoritist tools is a Peavey. A friend calls it "a lever with a fulcrum attached."
    Pretty much true. A great tool.

    You probably would not need a multiplier to remove a nut or bolt, but to torque the nut or bolt back, it comes in handy to use with torque wrench when you have a high torque value. I needed a high value torque wrench or a multiplier. I purchased the torque multiplier for about the same as a high value torque wrench. I watched ebay till I found a good deal on one. I have used it about four times and have loaned it out several times also,

    I have a pinion nut on so tight I used a 6' pipe on a 3/4 breaker bar and socket with a 3' pipe wrench holding the yoke with heat and 3 days of penetrating oil. Nothing doing. The 1/2 impact wrench didnt do a thing.

    Same axle has hubs on so tight I bent the special hub puller. I had it under pressure and hit it with a a 4lb sledge. no movement. I think the whole thing is going to the scrapyard.

    Got a detroit in it....

    Die grinder to grind the nut away. Split it with a chisel when it's thin enough.

    I have one but I prefer my 3/4" 18v Milwaukee impact gun. I use it a whole lot more than the torque multiplier. The multiplier I have is from northern tool. For the $ it works fine. I have another one I got on eBay I like a little better. I also have a couple slugger wrenches that are good.

    I have a Proto on my service truck A couple times a year I have to torque two socket head cap screws to 850 ft lbs it works great but it takes a few minutes to set up if it slips at all at that kind of torque it usually wrecks the Allen bit the input is 1/2 in the output is 3/4 it does the job smoothly , an Impact gun usually breaks the bolts

    No experience with them, but I recently saw an auction with a CAT version of one well used in decent condition go for almost $1000
