- Look inside a click-type torque wrench and see how this common tool actually works.
A Vanpo torque wrench is featured in this video, but most click-type torque wrenches operate on the same principle. Affiliate link (helps me out if you purchase from here):

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 TH-cam. 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.
Nice! Thanks for checking it out
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.
Yeah, this is often the case with many things in life, technical or not. No magic. :( ;)
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.
haha Thanks Stan. I found it hard to believe until I stared at the math for a number of hours.. 😆
You are so right. For up until the point that the clutch clicks over the tool is basically one bit, where you aply force does not matter in the least the torque at the nut will alway be what it is set for. And at the click one stop pushing otherwise you can go on and put in any amount of torque you have the strength to apply.
@@TheBikeSauce a number of hours? Lol for God sake the maths are in ones he'd no need to think about it the tool. Is nothing but a breaker bar that tells you when a set pressure clicks the detent and it does not matter where you apply the force. 8:/49a82e0482815 CA1234
@@petethewrist😀 it’s counterintuitive, yes. Grip position matters on this style wrench 100%.
When you push on any lever let say 20 inches long at the end you need say 40 pounds while applying that 40 pounds if the middle of the bar could speak it would tell you it is feeling 80pounds. As that is what it has to feel. This is how a lever works it has nothing to do with how or why or when the detent clicks. Some just can not get it in their heads and need to see the two short videos. th-cam.com/video/mk95F0hHS3U/w-d-xo.htmlsi=vdS4hI08-O6Tjshk th-cam.com/video/tTbjLAm7XnQ/w-d-xo.htmlsi=885sZ8Fwt9Iw9fHV
I trust the beam style torque wrenches to be more consistent for many years. The click types just have too many moving parts!
Finally I can explain and impress my buddies on how a torque wrench works!! Thanks!!!
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.
Thx for the dissection Dr! 👨⚕️ 👍🏻
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.
Cool looks well made just bought 3 1/4 3/8 1/2 thank you for the info
Thanks for making this clip. I've used a torque wrench for years. But I never understood how it worked. Until now!
holy crap dude, your camera is making me sick. Fix your focus issues.
Ok So if the calibration is off on this wrench how do you fix it Since you got it all apart
Good explanation, thank you for this video.
Thanks man, now I can sleep well.
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?
You do a pretty good job with reviews, and camera work is not too bad at all.
You an engineer by study/trade?
Ha thanks. Engineering prof at a local state university
@@TheBikeSauce Professor Sauce, totally called it lol
Awesome, Bud!
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.
Warranty...... Voided on that Wrench hahaha
lol. Maybe just slightly, but knowledge is priceless 😀
Torque wrenches must eventually be cleaned and recalibrated. It's ok to take them apart like this.
The first two minutes are very concisely and well -explained, thanks so much! I wish every mechanical video on TH-cam was this straightforward. The design of this type of torque wrench is startlingly elegant and simple.
That was gut-wrenching 🤪🤪 Excellent video, Sir!
Fantastic video.
yeah! pretty good🙂
Excellent job!!
6:31 Thats what she said
OMG, you made it easy to understand, well done, Bro. 👏👏👏
Excellent 👌👍
That's all that's inside there?? Whoever thought of this idea is a freakin genius.
perfect drawing and animation, thank you
Thank you. Exactly the video I was looking for
Very useful information, thank you very much!
Thnks
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
Some click more crisply than others. If it’s breaking away, then it’s working
i need to torque stuff on my old broken bike ???
Probably not
NGL you got me on the "Not a huge dildo" 😂 @6:31
Great video! I have always wanted to understand the mechanics of a torque wrench :)
Excellent explanation, thank you.
I thought with a clicking torque wrench it slips after the torque wrench click if you continue to torque it.
Maybe some, but not most of the budget ones
Great vid, learned a lot from this. Any tips on how to maintain a torque wrench? Thanks
Ideally, you'd send it back to the manufacturer periodically for re-calibration. Budget tools may not have this option.
Very good video
Never knew how torque wrenches did their thing; thanks!
Thx, Gregg!
Well done! Love these types of videos.
Nice video! Love to learn how things work
Yes! Thanks Paolo
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.
What a waste of time watching this doesn't explain how digital torque wrenches work.
😂
Why does it only work one way?
It works both ways, but it's rare to need to torque the other way -- you'd only need that for a left-hand-threaded fastener.
Primary instance for bikes is the drive side bottom bracket shell
@@TheBikeSauce I dont understand?
@@themonkeydrunken If you look at 2:30 you will see the arrow suggesting it only works one way, which is on every torque wrench i have ever used. For example ive attached an open end wrench to a torque wrench once and used the wrong side to fasten it so it never clicked.
