Torque Wrench Repair???

Well, crap. Just got off the phone with a couple different Sears stores close to me. Not only did they say they don't warranty them (which I wasn't looking for), but they also don't carry repair kits. I think I need to do a little more online research and see what I find. By looking online, it looks like they use the same mechanisms in the 1/2" ratchets.

I do have another one I can use. I just really like this one because I inherited it from an uncle who passed away.
