I bought a cheap torque wrench four or five years ago when changing a head but since then I've been fairly lucky and haven't needed it. Rather shamefully i have been using it on and off (and more on as time passes) as a breakers bar. Since these seem to cost more than torque wrenches I shouldn't really feel guilty I suppose.
Anyway I now need it again to change a couple of oil seals but it seems to have stopped clicking. No doubt I will end up buying a new one in the end, but the bodger in me would like to take a chance at fixing it or at least having a look at the complicated innards. Rather than just opening it up and have bits flying out, I have been trying to find a website which could give me a clue on what to expect inside but these days Google just returns lots of sleaze bags trying to sell me one and nothing useful.
Can anyone suggest any useful websites to look at or give hints from having done this before.
Many thanks in advance.
