A common problem of this type of torque wrench is that they don't "click" from the factory. This video shows the disassembly and rebuild to fix this problem.
As luck would have it, I had the calibration video up shortly after this TR repair vid. A commenter told me it was not correct so I deleted it. Basically what I did was hung a 20 pound weight off the TR shaft from a point 12" away from the center of the ratchet head. Set the TR setting to "240 inch lbs" and adjust the "click" to that point. While not exact, it's close enough for oil pan bolts and the like needing a torque of around 20 foot-pounds (240 inch-pounds)
@@ccarlley Nothing wrong with that, torque is force times distance. Sir Isaac Newton agrees with you. You could compensate by introducing little fudge factors, good enough for non-discriminating DIYers.
@@kimchee94112Yes, decades ago I torqued cylinder head bolts on an old Land Rover with a measured bar and a spring balance intended for fishing. Someone came by, said "You can't do it like that" and checked with an expensive torque wrench. Every one was correct.
