I can pick myself up off the ground leaning on the wrench, so I figure 160 lbs 6" out- about 80 ft-lbs. Should that be enough to get it off? Or do I need a bigger wrench or a vise? And I'm turning opposite the driving direction (w/ the wheel infront of me, wrench between me and the freewheel, and freewheel on the right, I am pushing down, if that makes any sense), turning in the direction that it free-wheels, so I'm doing it right, right? Thanks.
