The resting length of the spring is critical. Since it has weakened, the amount of travel of the adjusting thimble is no longer consistent with the spring travel required. It now takes less travel of the thimble to attain a desired torque setting.

@F16_viper_pilot 6 месяцев назад

Yeah, the compressed spring across the same torque range is a problem. He can calibrate somewhat for a sub range of the total range (like maybe the top 3rd or 4th), but the other ranges will always be off, thus significantly reducing the useful range of the device. Better to just buy a new wrench for $50, as it seems likely this wrench didn’t even cost that.

@theodavies8754 10 месяцев назад

Nicely done video. It's still useable as a long ½" ratchet wrench. Calibration is off. Will measure under from the end. Will measure over at 12" point. Measure from the point you hold. The force at the vice jaws from a ½" square being turned is awesome.

@gamerin 2 года назад

I know this is 2 years old but something to think about for others: the measure of 16" is not consistent as the higher lb the shorter the length of the wrench becomes. I am confident that's why you are seeing variations in your numbers. None the less great video and explanation. Most conscience video on RU-vid.

Thx. I just did it for fun to see if I wanted to do RU-vid vids hehe glad it was helpful

@johnny0454 6 месяцев назад

That's why there is the channel in the knurling of the handle. That is the exact calibration point as it relates to length. It should match the calibration at any of its torque settings at that channel. Ideally, for the most accurate results, when using a clicker type torque wrench, that little channel would be the only place you would apply force. It does matter where you apply the force on the handle; because, like you implied, it's relative to the exact length from the center of the pivot point (center of rotation of the fastener) at which you apply pressure. Some people are much more accurate with a click style simply because they are more consistent with how and where they hold the handle so as to get more consistently repeatable results.

Springs don't weaken due to being compressed for periods of time. They weaken only by cycling. I have a craftsman microtork that I'd left set on 150 lb-ft (it had a 250 lb-ft max) for probably 10 years. I bought an electronic gauge to check it, it was still just fine.

@soilmanted 4 года назад

My goodness you are doing this the hard way!!!! Yes there is a piston-locating pin that keeps the piston from sliding out the handle end and sliding too far toward the nut-turning end, but you do NOT have to compress the main spring, at all, to get the pin in. You can simply remove the the big pin, at the nut-turning end of the wrench, which is roughly 5 mm in diameter and 2 cm long, that holds the nut-turning head, with its attached tool-steel bar, inside the tubular main body of the torque wrench device. To remove the pin remove the E-clip that is at one end of the pin. Some wrenches may have another type of fastener to hold the pin in place, other than an E-clip. Then simply pull out the big pin. Once you remove the big pin you can pull on the nut-turning head and slide its attached tool-steel bar out of the tubular main body of the device. Once you do that, once you pull the head out just a little bit from the tube, you will have removed the pressure on the spring. Now - there are one or more parts inside the tube, between the tool-steel bar and the spring. Either completely remove the bar and take a look at what you have, and when re-assembling be sure to return all the parts to the same place they came from or, after you remove the head-end pin, pull out on the bar just barely enough to relieve pressure on the spring, relieve it just enough so that you can get the piston-locating pin into the piston. That way, everything between the spring and the head will stay in place.

@@PhoRunnerI took apart and put back together my Harbor Freight Pittsburgh 1/2 inch drive springy-clicky wrench model # 62431 a couple of days ago and it seemed to be working afterwards. However just before sending my message here, during the process of doing a little housecleaning, I found a little pin on the floor. A pin about the size of the torque-wrench piston locating pin. Now, it's not the locating pin; that is in its proper place. I don't know what the hell kind of pin it is that I found, or where it came from. It has a little rubber "cap" on one end and a circumferential groove in it. Maybe I tracked it in on my shoes from outdoors, I don't know. Or maybe I took something apart and forgot to put a part back in. I hate when that happens. This is driving me crazy. I know I won't stop searching all over the internet until I find an answer to my question: where the fugu-fish did this pin and its little rubber hat come from? All kinds of very important things will have to be placed on the back burner until I figure out where the pin came from. Because KNOWLEDGE is power and I like power.

@bobgreene2892 3 года назад

Thanks for a good, practical method for checking calibration with a known load. However, what I had expected you to do was to use/"try out" a Harbor Freight digital torque wrench adapter. These devices are usually much more accurate than a mechanical/spring-driven indicator. As a test with the digital torque adapter, you could apply the wrench to any nut and bolt, and tighten to the desired value for your wrench, based on the digital torque adapter display. Whatever the adapter reads, add washers until you closely match the adapter reading. As you point out, it is important to check accuracy at various increments down the scale, since value accuracy at the heaviest torque may not match the value accuracy at other settings. Of course, the idea was to do the accuracy check for $2.00, but you could not have performed the adjustment without your digital postal scale-- at some additional cost. Just out of curiosity, how many cars do you have in your garage?

@fitch8363 Год назад

Interesting video. But you should have been pulling at the center of the grip not the far end of the wrench. Where you pull will effect the result on a wrench like that. There are videos which illustrate why that is true.

@Crystalheard Год назад

Great vid! I am very surprised that the spring keeps its linearity pretty well even though it is (mechanically) damaged/compressed.

@PhoRunner Год назад

Springs are constant in nature if the coils are all the same. At least that’s what my physics teacher said

@F16_viper_pilot 6 месяцев назад

I disagree. It actually did not keep its linearity that well when you consider that it has effectively become more rigid than designed, and thus you’re going to see significant deviation across the torque range, which is exactly what he’s seeing, and would be much more noticeable if he actually took a reading at the top end of the wrench. The goal is to have roughly 2 to 4 percent precision across the entire range of 20% to 100% of the wrench max range. If he tries to calibrate the wrench to meet spec at the top end of the range then the mid and lower ends are going to be hugely off. The only viable solution in this particular instance is to replace the spring, buy a new wrench, or only use the wrench for some limited sub range of the full range.

Wish Sam's Club used a manual torque wrench on 4 of my new purchased tires. Something didn't feel right on my front tires pulsing while braking, an indication of warped rotors. Lug nuts way too tight and when Costco did that 20 years ago it cost me $400 then for a new set of front rotors on the Volvo. The lug nuts installed from Sam's Club couldn't be removed with my 450 ft-lb Milwaukee torque wrench. What were they using? I retorqued it to 78 ft-lb on all 4 of the tires, hopefully no damage.

@jchrist1986 4 года назад

So, my question seems dumb, but idk whay sort of pressure you were faced with when installing the “piston locating pin” but I can’t understand ,(without that clearly defined information....maybe later in vid? At 15 minutes right now), why it wouldn’t be simply to drill a proper sized hole in a block of wood for the torque wrench to slide into, for control purposes, resting it’s head on something semi forging(more wood?), and placing the wood between your legs to some other reasonably rigid stand-type device/setup. And forcing the spring to compress with your hands as you aligned and installed the aforementioned pin? Seems that when relying on a jerry rigged floor jack hack, you leave far too much to chance. But, still early in the vid.....

@jamesweber4938 3 года назад

Inside the torque wrench there is a piece that does the clicking. Take that piece apart and remove all the original grease and replace it with fresh wheel bearing type grease and it might work again. Mine did. There should be two small ball bearings in the clicking device. Make sure when you put the clicking device into the handle that the two small ball bearings line up with the adjustment Allen key screw that is half way between the handle and the square drive.

@Muddy283 Год назад

There is one critical factor you have got wrong in this otherwise excellent video. See this video by *Park Tool,* the Rolls Royce of manufacturers of quality bicycle tools: _"Tech Tuesday #13: Torque Wrench Accuracy"._ It shows how you will only reach the correct torque on the bolt you are tightening if you apply the weight to the correct point on your torque wrench tool (for Park Tool torque wrenches for example, the correct point is exactly in the middle of the handle). The above factor seems crazy and counter-intuitive, but it is true! The following video: _"Why GRIP Position on Torque Wrenches MATTERS!"_ - although it is beyond the intellectual pay grade of my poor and inferior brain to understand - apparently explains the physics and the mathematics behind this weird and somewhat complex physics phenomenon. So you are wrong to apply the weight at the end of the torque wrench tool, and your results will unfortunately be incorrect even though you have quite correctly applied the equation to adjust the ft/lb from 16½" to 12".

@@PhoRunner We're all interested in checking the calibration of our torque wrenches (very important to do!) and if necessary recalibrate, but without having to pay the same (or even more) as it cost to purchase the tool in the first place. That's very probably why your video has attracted so much interest.

@leebrand2172 7 месяцев назад

Categorically it is incorrect to say that the torque indicated is affected by where you hold it. Anywhere after the pin will be 100% consistent because the shaft is a solid structure. You can move yourself hand around. The perceived force you feel will change because you are changing your mechanical advantage. Where it does make a big difference is when you attempt to apply a known exact quantum of force to the machine. Generally for calibration. Now the lever length is critical and the distance from the pivot centre to force point must be measured exactly. This allows you to calculate the torque that you are applying to the machine. In general use the machine doesn't care how much force you apply where. The load is directed to the cam/spring interface and that's where the deflection is in fact measured.

@F16_viper_pilot 6 месяцев назад

Interesting video, but is it that useful? For $50, just replace the torque wrench. The one you bought was cheep and you got your money out of it. However, if this was a $300 torque wrench then, sure, fix it, but do it the right way by replacing the spring. You ruined the wrench and are trying to compensate for what should be a section of flexible spring with inflexible metal washers, and the spring is now also more rigid from compression, meaning that the shorter more rigid spring has to still cover the same torque range and thus has lost significant resolution across that range. The values you’re getting after all the work you did are not acceptable for the purpose of this device. Just my 2 cents.
