In all honesty I've been a tech for 4 years and never new this. Great job on explaining this. We never stop learning. Well if you have stopped learning you have either left the industry or stop giving a crap.
Great presentation! I made my first torque wrench out of a box-crowsfoot wrench, a ruler, and a fishing scale. It worked quite well. Again, thank you!
You just explained the concept of torque to me better than any University professor or soyence youtuber
Awesome! I've been a shade tree mechanic for 40 years & did not know this? TY dude!
Very helpful. I was always doing 90 degree on crowfoot, and from now on I'll be able to do straight angle.
This is the first time I've watched this video and now I'm a subscriber. This is really helpful. Thanks
Wow I really needed this. I have a nice torque wrench and did not want to spend more for the few times I need to tighten some line sets. Saved me big time!!!
Thank you for this video! I learned a lot from your demonstration of how to use a torque wrench, and now I'll be able to torque bolts into the spec in tight places.
Excellent. Answered perfectly the question I was seeking to have answered. Couldn't have asked for more. Thanks for making this!!
Thank you sir, I'm a longtime sub, and enjoy you're teaching, also I used you're videos on testing all my relay's. I'm Diy, 4& 1/2 year's learning, I'm still learning still much to learn.
Great job explaining this for newbies like me. I really appreciate your time and effort in sharing this with us.
This was a truly great video. You showed an old dog a new trick that is very valuable to my retirement income. Thank you for sharing.
Great video. Thanks for posting. Simple and right to the point!
Glad to see you back!!! Love your videos!!
Excellent tutorial, Sir. This is very useful everyday information.
hey thanks for coming back to youtube!
Thanks much!!! I was trying to figure this out on my own but this came in super handy - great job!!!
This is a great idea if someone wants to save money, and doesn't want to buy an endless amount of tools while maximizing the use and dollars worth of their main tools, thank you for the idea!
Your videos are always very informative. Thanks.
Miss your videos, man. Some of the best on TH-cam. Also, I have those same Costco shelves and they're just as messy as yours lol.
Good to see you back
Flawless explanation, including the math is fantastic!
Great topic and great tip. Made it easy to wrap my head around.👍
We were just talking about this at work this week!
Pure AWESOMENESS! Best explanation ever!
Excellent information and explanation! Thank You!
Thanks! I too, need to torque my lineset for my minisplit. This really helps!
Thanks! I've been wondering how to properly do this.
Now I know :-).
Great video. Helped me in installed a new muzzle break on my rifle.
Very simple explanation, great vid
Thanks.
I wasn't aware of the calculations.
Awsome.
Nice job! Old tech once told me to drop 5 to 7% and you’ll be in the ball park. Never had a problem with doing it that way. Seems like math wins again. Thanks
Extremely helpful. Thank you!
Thank you for making this.
Wow man you just blew my mind!
Thank you so much
Thank you sir, clearly answered a question I had.
Nice job, good explanation.
Excellent video, thank you for sharing
great info. keep the vids coming
Very nice information, never knew this
When using self locking fasteners don’t forget to add drag torque to your required torque to ensure the fastener isn’t under torqued. Also most torque specs are designed with the fasteners lightly lubricated unless specifically stated to be dry.
Good info. 👍
The fact is that every fastener is different when torqued. regardless you can't know the exact drag.. You have to torque turn the bolt to get the correct clamping force
Thanks for the valuable tutorial. Does this applies to an socket extension bar also?
I’ve looking for this info. Thx a lot.
Hi thnxs for your videos and they are great but I have a 2003 Peugeot 206 and I wonder it really runs rugh and when it comes to heavy rains it really runs smoothly and i always wondered if it is cylinder head or the clutch or the sensors off but the problem is that the pedals shakes normally under your feet and in heavy rains it really gets really smooth just as good as new could it be of missfire or coilovers? Or injectors? No error codes are seen. Could you plz help me out with that .
I like the harbor Freight torque wrench 👍 I have it too, can't afford the brand name ones, lol. I tried 90 degree best I could when tightening the wonderful control arm bolts when under load for the B5 audi. Try it one day. Very fun, lol. I used tq adapters. So nice. To bad this tool u linked is 200.00. I'll stick to your method 👍 thanks for sharing
This will be very useful for torquing the rear axle nut on my motorcycle
What type of motorcycle is that, that you can't use a regular socket? Also, the rear axle nut torque doesn't need to be that precise.
Great video brother!
Nicely done!
Finally an accurate explanation! Now we just need you to explain the use of “extensions” with a torque wrench;) and how they magically reduce static torque!
I don’t think they do. On a impact they do, due to less impact reaching the socket
Extensions don’t change the torq … ?
Great explanation
First one to like ! I love this guy’s content but never been the first to show it. Well… time zones helped me this time around !
Great info!
Nice information
Good work
To help with the measuring and math read the manual for your torque wrench. A lot of good torque wrench manufacturers will have a page with the measurements provided and a plug and play equation.
I used crows feet to torque my b5 control arms and I knew something felt off. I kept re-doing the torque until it felt "right" which was probably when it was set at 90 degrees. Now I know!
I think that an adjustable digital flare torque wrench would be easier and more precise for ductless flared tubing lines for minis, although I haven't tried the yellow jacket torque wrench and wouldn't know if that mechanical tool would work better (and be more precise) than the adjustable digital wrench
For those saying this is wrong, you are actually wrong because the technician in the video did not extend the length of the torque wrench. Applying the torque at 90 degrees like they did will give an accurate torque to the fastener. This a proper way of tightening a hard to reach fastener
Hi there.If you use a digital torque wrench adaptor its the same calculation?Thanks in advance.Greetings from Greece.
Good video . Hope you are doing well my friend 😁
nice information thx
2:13 - is that even the same distance when the crow foot has moved upwards like 5cm, away from the measurement point ? or this Pythagoras move is not that big anyway, so it doesnt matter that much as the straight forward movement would ?
Great video, but I thought I wasnt supposed to trust you . Its nice to have you back on a regular basis.
I think my head gasket is blown. It just did a big exhale at a light, and spewed coolant every where. I see radiator cracked a bit open at seem, eventually trynna to get home it cracked. So I replaced the radiator.. I did not see oil in the coolant.. before all this happened.. in the radiator itself.. when just inspecting here and there. How will I know. I am going to fill up new radiator today. 2001 GC laredo 4.0 6 cyl 126 k miles. Help a girl Out. Please.
Thank-you , maestro .🙂
Dude good morning!
Hi bro..
Can u tell gud quality cordless polish machine
Simply compensate the approximate difference on the gripper... I learned this 'nifty-trick' from an old friend who no longer works for Concorde 🤠
How much does it tell you when it's tight enough my husband usually breaks it because he puts it on too tights
Great video, you can teach an old dog new tricks thanks
Awesome!
Can you please do a paid video course on auto mechanic and specially the electric side? I really liked your STFT & LTFT video and the way you put it please do a paid series like this with all resources.
I use that formula all the time at work. Works fine. A little over the top to say ‘never do this’. Just like anything you should know what your doing before doing it. That’s all.
i swear i clicked the bell like a year ago but here it is unchecked.....YOUUUUUTUUUUBE!!
thank you
Good one
Thanks bro. Now i know.
What if you use an extension?
Proper job
It does not matter how you use the crow's foot because the torque wrench is measuring torque. That torque transmits directly through the solid crow's foot right over to the bolt without changing. The bolt will apply an exact opposite amount of torque to balance what the torque wrench is applying. Both torque and force will be balanced is such a static system. I learned this in statics engineering class 34 years ago.
What you are saying is that the torque wrench will always measure the same amount of torque at the head of the wrench - this is true, but the amount of torque applied to the nut in the crows foot is effected by the length of lever from the center of the torque wrench to the center of the crowfoot. This is why to calculate the difference. If the total lever gains length, then the measured torque on the wrench is less than the torque on the bolt. If the total lever loses length, the measured torque on the wrench will be more than the torque on the bolt. So the crowfoot orientation does matter if you want to know the torque on the bolt. It doesn't matter if you only care about the amount of torque on the wrench.
I think, most everyone using a torque wrench wants to know the amount of torque on the bolt, don't you?
If you added a cheater bar to the torque wrench, THAT wouldn't make any difference. So, those marks on the handle don't matter really. But since the wrench is calibrated to radius=0, as soon as radius = anything else, the measurement no longer represents the torque on the bolt, because there is the added effect of lever. So it gets multiplied by some factor of sin or cos.
This is some fascinating sh*
I think the marks on the handle are for calibrating the screw dial. Not completely useless.
The key here is that torque IS force, it's just force measured about an axis. A lever is a force multiplier.
Multiple axis in a single system gets super difficult to calculate, I think once there is 4 axis, actually no mathematician has figured how to calculate it.
Yes it really does tie the conceptual circuits into loops don't it?!
Fantastic, thank you! Important to know.
Thanks, *NOW* you tell me. I just got through replacing the injectors on my Detroit Diesel, torqued them all with a torque wrench, all with a crows foot. Think it all worked out okay, it runs, doesn't leak, haven't stripped any threads (that I know of), I'm good, unless it blows up with me in it.
To be honest the variation that little amount of distance from the end of the torque wrench wouldn't make alot of difference anyway.. You'll be fine
@@brettwalkom948, Thanks, appreciate it. I forgot all about me making that comment. Truck still running good, no leaks, and it hasn't blown up, it's been about 15k miles since then
@@vivillager people get anal over this stuff.. In reality most bolts have a plus or minus so many ftlbs anyway
Extension calculations?
Any of you watch watch Wes work? He had a bolt that he couldn’t get to with a toque wrench so I told him to try this cool to know that you can do it accurately
How much torque do you need to slice an avocado in half? 🤔
Grandpa's logic never failed, he would just torque and say, I guess that's tight enough.!
Just found the channel and liking the content. Though I can't get past how this guy looks like the offspring of Andrew Camarata and Joe Mantegna (David Rossi of CM).
I was hoping this will be more practical on how to keep the crowfoot in position and tighten down what you’re trying to tighten down without a locking capability
How did you derive your equation? I thought it was the perpendicular distance? Is your equation based on the perpendicular component force?
That is based from formula T=Fd. Consider constant force (T/d) and use “d+2” for the spec and “d” for setting.
anything off center of the anvil you have to use the torque formula.
ty for the psa
I always look at my wristwatch when torqueing bolts and nuts.
What will REALLY blow people's minds is the realization that torque specs are based on fastener perfection, and has nothing to do with the important physics of securing the fastener correctly. That's why properly torqued fasteners still occasionally fail.
Does the torque change if I use socket extension?
No, the perpendicular distance is the same. Similar to him putting the crows foot at 90 degree angle.
Does this work for digital wrenches as well?
Yes.
I have a set of crows foot “sockets”, but I’ve never had the need to use them for anything. I really don’t see the usefulness of them.
If the crows foot center is 2" farther away from the center of the torque wrench socket plug, why not just place your hand centered over 2" farther up the handle?
Because that doesn't change when the wrench clicks, that just changes how much effort it takes for you to make it click.
@@mt186 Ah, thanks!
That's funny, I've just been using the different buttons on my Milwaukee half inch drive impact to tell me the torque
You are a. LifeSaver
Just to clarify - that formula is correct if you're only holding the torque wrench at the handle and pulling, so that the reaction to your pull is only from the fastener. If you're holding the torque wrench at two places along its length and pulling with one hand while pushing with the other to rotate it (like you might do to stabilise the wrench if you're using an extension or if it's in a tight space at an odd angle), this will not be correct any more and the torque on the fastener will be lower than the formula suggests. The technique with the crow's foot rotated 90 deg is probably more consistent, otherwise be careful only to hold the torque wrench at the location you assumed in the formula, and not anywhere else as well. Great video though! I'm a structural engineer doing some work on my car, and I'd never heard of a crows foot adaptor before but it's just what I need.
That's a good way to explain it. I would like to see the different angles shown on a torque measuring device. My mind is telling me that at a right angle it would actually throw the torque off
