I've had a Sears craftsman torque wrench for 50 years and it started to vary in settings so I went on line and found an article on how to disassemble it, clean it, lube it & put it back together. To reset it, the end of the handle had solder in it, melted that out to access the adjustment knob. Then compared it with 5 other torque wrenches had access to and adjusted accordingly, now it works great, in fact the click feature is very quiet & subtle .
