Beam style Torque Wrench ?
« on: April 25, 2019, 12:27:00 PM »
Recently changing sprockets on an R6 Yamaha. ...and we found the beam style torque wrench to be easier to use than 2 different clicking wrenches.
Those two (mid priced, clean, rarely used, stored properly) disagreed too much on their readings.
So out came the beam style, a piece of tape edge for our aiming point - and Bob's your uncle! Big nuts tightened.
I also never use any torque wrench on anything but the 2 CVT nuts, and at the axles of a scooter.
Use new washers, finger tighten , then a snug -- and STOP! Has served me well on alloy engines since the 60's.
I also never do serious engine rebuilds where proper torqueing is probably necessary.

Pretty hard to get it wrong with the simple beam type!

Love my beam wrenches...Old Craftsman ones..actually made in the U.S. 
Simple tech, not much to go wrong with 'em.  They've taken years of use & abuse.
I still use those by preference.
I did break down and buy a HF click wrench a while back  though & haven't had any issues with it, it does fit places where I can't get a beam in and actually read it.
I do check it against the matching beam now and again, so far no issues, but click wrenches can go off & it's recommended you do verify & adjust 'em now and again. (no idea how to adjust it, I'd have to google that).

I only use a click type torque wrench, and have no experience with the beam style type.

The click type wrenches do have limits - the most common problem is that it actually needs to be unwinded after it has been used. The reason being - the tension on the spring needs to be released, otherwise the lifespan of the spring will be shortened.

Another possible problem - the market gets flooded with cheaper versions these days, and I am not sure about quality on the cheaper models.
Also - these things have a limited lifespan - and is actually suppose to be "calibrated" after it's been used for a number of times.  In our country the better type wrenches usually come with instructions in this regard - but I'm not sure whether the dealers who sell the wrenches have technicians who can do calibrations.
The cheaper ones in our country come without any instructions.

Fortunately I don't use my torque wrench that much - it should last until I finally bite the dust.
