So, I buy my first torque wrench today. The directions seem simple enough, figure the setting, set them, and torque away until, well, until what? I hear a click but is that THE click? I'd expect so as I'm moving in the non-rachet direction.
Problem is, this is a Tiawanese translation into French that I'm translating into English and it doesn't seem to make any sense. There we have the case for cheap tools in a foriegn country, no?
Anyone know of a FAQ or some place with some good info on how to use these suckers? It is the micrometer type clé dynamométrique.
Merci,

TORQUE WRENCHES
At times, you will need to apply a specific force to a nut or bolt head. At these times, you will use a torque wrench. For example, equal force must be applied to all the head bolts of an engine. Otherwise, only one bolt may bear the brunt of the force of internal combustion, ullimately causing engine failure. A torque wrench will allow you to apply the specifically required force. The three most commonly used torque wrenches are the deflecting beam, the dial-indicating, and the micrometer-setting types (fig. 11-26). When using a deflecting-beam or dial-indicating torque wrench, you visually read the torque on a dial or scale mounted on the handle of the wrench.
The micrometer-setting torque wrench, however, indicates the torque value by sound. To use the micrometer-setting torque wrench, you unlock the grip and adjust the handle to the desired setting on the scale; then, relock the grip. Next, install the required socket or adapter to the square drive of the handle. Place the wrench assembly on the nut or bolt and pull in a clockwise direction, using a steady, smooth motion. (A fast or jerky motion results in an improperly torqued unit.) When the torque applied reaches the required torque value, a signal mechanism automatically issues an audible click; and the handle will release or break, moving freely for a short distance. The release and free travel are easily felt.
This feature indicates that the torquing process is complete. You should use a torque wrench that reads about mid-range for the amount of torque to be applied. Manufacturers’ and technical manuals generally specify the amount of torque to be applied. To make sure the correct amount of torque is applied to the fasteners, you must use the torque wrench according to the specific manufacturer’s instructions.

CAUTION Be sure the torque wrench has been calibrated before you use it. Remember, the accuracy of torque measuring depends on how the threads are cut and the cleanliness of the threads. Make sure you inspect and clean the threads.

Usally it works like a normal wrench, turning the opposite way from what you are going and the pawls will click. If you are tightening the botl/nut then you turn until you hear a loud click and that is the setting you need.

K&N Induction Kit On A Panda?? Never!!!

Pete - possibly my problem is that I was "rachetting", moving in 1/4 or 1/3 arcs, then reversing, to continue, as I would a normal socket wrench. Should one keep the motion going in the same direction?

Use it as a normal wrench. There's usually a very obvious click when it gets to the right torque.

So, this turns out to be pretty easy and I think the advice I got from a pal at work could be good advice for anyone.

You get a new wrench, not sure how it works - get the torque data for your wheels (my book said 88 newton meters) and use the wheel lugs as a test. This let me hear the "click" and get a feel for the wrench and how it responds.

Worked like a champ!

You probably notice that as well as hearing an obvious click you should be able to feel it too.

I don't know if yours is the same as mine, but if I continue turning beyond the click then it will still tighten further, so be careful.

To heavy-handed people like me, torque wrenches are a godsend. Ask any member of my family who's tried to turn on a bathroom tap after I've turned it off!

Regarding head re-fitting:did you use again the old valves' shims or you bought new ones to obtain the correct gaps[?]And then, does the manual advice to check bolts' torque after covering a low mileage (maybe 1000km or more)??

Passion has neither brands nor models!

La passione non ha nè marche nè modelli!

Old shims and no advice on checking the torque. I'm not sure you can check it again as the Porter book calls for 30 nm then +90 and +90 degree turns, which is, I think, beyond what the wrench can read, or at least, it sure feels that way!

Anyone know the torque for the flywheel on T-Jets?
