How Torque Wrenches Actually WORK! 

Man! You are a genius. 45 seconds from your 90 seconds video and I completely understood how a torque wrench works. The graphics is spot on and so is your explanation. There are so many poorly prepared or unfocused explanations on RU-vid. You are a great exception from that. Thank you very much.

Thanks for the chalk talk and disassembly. Now I know why the instructions for my budget torque wrench tell me to dial it back to the lowest N-m setting when not in use. And I now know why I should hold it at the middle of the handle. Keep ‘em coming.

Thanks for making this video I was trying to imagine how the internal mechanism of a torque wrench worked but it is surprisingly so much simpler than I thought.

Thx for the dissection Dr! 👨‍⚕️ 👍🏻

Finally I can explain and impress my buddies on how a torque wrench works!! Thanks!!!

Well done! Love these types of videos.

Great video! I have always wanted to understand the mechanics of a torque wrench :)

The first two minutes are very concisely and well -explained, thanks so much! I wish every mechanical video on RU-vid was this straightforward. The design of this type of torque wrench is startlingly elegant and simple.

OMG, you made it easy to understand, well done, Bro. 👏👏👏

Good explanation, thank you for this video.

Thanks for making this clip. I've used a torque wrench for years. But I never understood how it worked. Until now!

Excellent job!!

Very useful information, thank you very much!

Excellent explanation, thank you.

Thank you. Exactly the video I was looking for

Fantastic video.

perfect drawing and animation, thank you

Nice video! Love to learn how things work

Great vid, learned a lot from this. Any tips on how to maintain a torque wrench? Thanks

Very good video

I bought a cheap torque wrench and it only worked once. After that it doesn’t click anymore. I almost damaged my bike thinking that it should click eventually. I tried fixing it but what is happening now it actually clicks so easily even after compressing the spring further? The clutch it has is similar to yours, a metal cube. I tried adding grease and also removing but with no success. What do you think could be the problem?

Sir I just want to thank you for having such a curious mind that asks “how does clicky clicky torque-y torque-y work?” You’d be surprised how many times I’ve been told I’m wasting my time and ruining tools because they’re dissembled at the time.

Excellent 👌👍

Thanks man, now I can sleep well.

Holding the wrench further to the handle end should apply more torque to the turn axis but it should not affect the measurement of the torque. I saw the impressive, previous video, but remain incredulous on that issue. Also, and perhaps you mentioned this, the accuracy of wrenches decreases over time. I was just praising your videos last night to a well-known bike blogger, so please know generally I'm a huge fan. All the best.

I trust the beam style torque wrenches to be more consistent for many years. The click types just have too many moving parts!

Thnks

You do a pretty good job with reviews, and camera work is not too bad at all. You an engineer by study/trade?

Hello Sir, I just received my new torque wrench, but apon testing it doesn't really making a clicking "noise", I can feel the handle break away in my hand but that's it, can't really say that's a distinct click

yeah! pretty good🙂

as a programmer, as i get more into mechanics its kinda crazy how simple it seems to me. I watched a video on differentials and i totally got it within a few minutes. After i saw the parts of this tool it made intuitive sense. Man its great seeing that my struggles with complex theory and unintuitive problems actually has a carry over to real life.

That's all that's inside there?? Whoever thought of this idea is a freakin genius.

I thought with a clicking torque wrench it slips after the torque wrench click if you continue to torque it.

Never knew how torque wrenches did their thing; thanks!

That was gut-wrenching 🤪🤪 Excellent video, Sir!

i need to torque stuff on my old broken bike ???

6:31 Thats what she said

Warranty...... Voided on that Wrench hahaha

NGL you got me on the "Not a huge dildo" 😂 @6:31

Why does it only work one way?

Low cost shouldn't be that big of a deal if you are only using it on rare occasions. I imagine a lower cost one may simply have parts that will wear out quicker. I would hope they calibrated it properly and just used softer parts that are not going to last as long. This would make it OK for changing a transmission pan gasket after having the pan off to clean it and install a clean filter. For my Nissan they spec 7 to 9 foot pounds of torque . My problem is I don't have anything that goes that low. I would love to clean that pan. My theory on why it does not immediately go after an emergency stop is that the sediment in the pan is disturbed and momentarily clogs the filter. If you didn't know you would think that you broke the transmission because of that @-hole who didn't look when pulling out. I try my best to avoid that situation but I absolutely refuse an accident I can avoid if there is even the slightest chance I can avoid it. I know that hard stops and acceleration are bad for transmissions in general and so I prefer to come to a more graceful stop. I am not one of those jerks who rides the brakes a half a mile from where I am stopping but I also prefer to be gentle with the brakes. I don't care for having warped rotors. If anything I anticipate it feeling more like it did with fewer miles since there would be less debris in the pan to obstruct the filter. The CVT has a small second cartridge filter and changing it helped. Some people might not believe in those little things making a difference but they do make a difference. Of course they are probably the same people who have the original oil, air filter and brake fluid their vehicle left the factory with 10 years ago.

I always wondered what is inside them. I do realize it is more complex than just changing the length of the handle in very small increments. That may be a part of how they work but a very poor and uneducated explanation IMO.

holy crap dude, your camera is making me sick. Fix your focus issues.

What a waste of time watching this doesn't explain how digital torque wrenches work.
