Ingersoll Rand Front tire Changer Hurd Thunder Gun 1/2" Impact Side Exhaust

Jimmy customizes the location, shape and size of the gun's exhaust port as requested by the customer. "Front tire changers want the port on the side because brake dust would blow in their face with a standard front exhaust. The new one has bigger port for more rpm." He says there's always a compromise between rpm and torque, "but in this situation you need both. So with this gun, torque will be the same off and on…it's just a little slower going on so you don't get the nuts too tight. If they're too tight, it can take more than 190 ft-lbs to remove the nuts. That might only take half a second (more), but that could be enough to lose 15 spots on pit road…The better teams hit 5 lug nuts in 8 tenths of a second and put 70-130 ft-lbs on each lug nut."

Jimmy also modifies the reverse switch. Each tire changer wants just the right stiffness on that button, and Jimmy can 'tune' the effort required to push it. "Whatever you want, I can to it. Sometimes the valve will wear down and I have to replace it, and there are different buttons too." But switch stiffness is determined mostly by size and composition of an O-ring, and by ambient temperature. This gun puts out 1000 ft. lbs. of torque and turns at 18,000 rpm
