Re: Torque Wrench Extension
Ok, here goes.....I called my former crew chief, a mere genius when it
comes to math computations.......
We had several occasions where the bolt on an engine crank or wheel hub
needed to be torqued well beyond the capabilities of our torque wrench.
I remember he had a method.....so here goes.....
Two ways........
1. He simply marked out a food on a long breaker bar and had someone of
the correct weight stand at the mark with the wrench horizontal.
Remember 1 ft. = x ft. lbs. So, if you had a nut that needed torque of
230, you would have a 115 lb. person stand at the two foot mark. or a
230 lb. person stand at the 1 ft. mark.
(Down and dirty and about 80-90% accurate.)
2. The other, more accurate way is to make (yes, I said make....we made
many tools....) or buy a multiplier. It's just an extension from the
prive some multiple of the torque arm length. It's easiest to make for
a "bending beam" type wrench, because you can measure the distance from
the center of the drive to the handle. For instance, if the beam length
is 18" then an extension 8-1/2" long would multiply the reading by 150%.
