I really did not want to get involved in this thread and I seriously think
it needs to end. SJ, I don't think you understood Fred's point. You should
have not added the length of the 2079 tool. That is what makes the math
wrong. Fred was talking about the wrench clicking, which it does when it
reaches a torque (or bending moment) at its socket, where it is connected to
the 2079 not around the crank pulley. If you lose the 1ft from your
equations the match checks out.
Just my 2 cents.
