Craftsman Torque Wrench rebuild/recalibration

Here goes...
Look up TeamTorque, only one I've come across lately.
about $50 just to clean, lube and calibrate. Any actual repairs extra...
So what Is your wrench worth!
Is it a Micro-Tork? I'd dis-assemble the head myself, clean and re-assemble.
Digi-Tork? I'd still do that before sending out for calibration.
Here's what I've seen on these.
Back the setting down below the scale.
You have a pin just below the head of the wrench, held with a tiny circlip.
Remove it and the head will come off.
Below that is a tiny piece of bar stock...A chip if you will...
It is probably dislodged, rendering you "clickless".
It will be somewhat self explanatory here, as there is a slight depression or groove it needs to sit in.
(Just for reference, IIRC, there ar only two more pieces that can fall out.
the little disc or plate with said depression and the spring).
Relocate the chip and re-assemble and see if you haven't cured it.
You've done nothing to change the calibration (that's done at the other end).
What happens is somebody backs the setting well below scale and that piece get dislodged.
Reason I say have at it is those wrenches aren't much more new than possible repair costs, and you can check calibration against known "good" wrenches afterward...
