Worlds best lug wrench

It's very heavy duty and comes in a nice little case. I noticed that there were no instructions so I contacted the seller. They responded quickly and said that there are no instructions.

I'm sure I can figure it out, but was wondering if anyone had any tips on using it. Reading all of the replies to this thread it looks like it can be used to torque the lugs back on, can anyone confirm this? I have a torque wrench that goes up to 160 lbs, and I'm thinking that I could use it along with a little math to get the right torque output. My wheels require 450 -500 lbs (manual says 475).

Thanks!

Which one did you get? If it is like mine (see post #4) then yes, it installs and removes the lugs nuts. I can give more details if yours is like mine.

Thanks, here's the one I picked up:


I think this one is different than the one you have.

If you can find the name on it maybe you can look up a owners manual online.

I was in your neck of the woods about two weeks ago. My brother lives in Rancho Cucamonga and his son was getting married at an old winery near Pala, California. I'll tell you what, Driving in California traffic is a tad different than driving in rural Kentucky traffic!!! I don't think my heart rate has dropped yet!

One of the many ZILLION reasons we moved OUT of CAL just over two years ago.

Be very, very careful in using that tool to re-torque those lug nuts. Based on the mechanical advantage of it, at least ours, with the 75:1 ratio, I can EASILY put close to 5,000 lbs of torque on those lugs. Needless to say, they'd break off way before that happens. To actually calculate what's needed for proper torque, using that torque multiplier would be to me, almost impossible due to not only the gear ratio but, there's also a "spring effect" too. That is, as you're applying torque to either loosen them or tighten them, there is a certain amount of spring loaded effect on the crank handle. In that range of spring effect, how in the world would torque be calculated?


This is why I simply cruised around on ebay 'till I found a great deal on my KD 150-600 lb, click type torque wrench for $75.00. Works great.

My version of the tool is 59:1. Maybe I'm simplifying it too much, but I divided 475 by 59 and came up with 8 and change. If I keep my current torque wrench at 8 (no change) that will get me to 472, well below the max torque of 500 listed on the lug nuts.

The reason I'm going through this exercise is to be as self sufficient as possible. Yes, I do have a roadside service and will be moving it over to Coach-Net shortly. But, in preparation for a future Alaska trip I want to have my bases covered. If I had no choice but to change a tire myself, I want to be able to do it. If I get the torque close, and that will get me to a tire shop then that will do just fine. They can take it from there.

I've been searching for a torque wrench like yours, and so far no luck. But I'll keep looking in case one pops up.
