i'd like to welcome everyone from around the world to steve rob reviews and today i'm going
to review the procedure that i go through when i'm actually considering using my torque wrench
so for a lot of people you know you've got like a torque wrench oh i've got lots of torque wrenches
and i don't rely on the torque wrench i prove that the torque wrench is capable of obtaining the
torque that i want so how do you possibly do that well you can go buy yourself a uh a real expensive
torque checker where you actually apply the torque it'll give you a reading and you'll verify that
you got the right torque but that could be like a thousand bucks maybe two thousand bucks or you can
go get your uh torque wrenches recertified how much is that going to cost you well it's going
to be more than your torque wrench is probably worth if you're using like inexpensive torque
wrenches like i have so how do you possibly do this well i've been using a particular jig for
years and years and years i just made a new one and i gave my old one to a buddy of mine
and i'm going to show you what it's all about and i'm going to explain to you the reason why i
use this particular jig it's like a bit of a hack everybody can do this it's just using a little bit
of logic and let's get to it right now but what i want to show you first is the torque wrenches
and the reasoning behind using a particular jig like i use to verify it because you know what
all this does is go click and whether you have a digital torque wrench a click style torque wrench
uh you have one that's got a digital gauge on the front or you got one that's just a beam style
or if you got like a uh there's very different versions of torque wrenches you can get a split
beam all the different calibrations are different the torque ranges are different but overall
when you're looking at a torque wrench the bottom 20 of the maximum amount of torque that can be
used for your torque wrench is suspect it's not that it can't be you know a good torque but it's
suspect so generally if you've got like a maximum of 100 foot pounds for your torque
wrench well 20 percent is 20 pounds so anything from 20 pounds under well they're saying you're
not gonna get a verified torque now digital torque wrenches i've seen them as good as uh one percent
some two three and four i've tested so many torque wrenches over the years some torque wrenches man
they are so far out and the owner has no idea that they're applying the torque and it's completely
bogus so let's take a look at some torque wrenches and then we'll get down to the testing
okay so let's just take a look at my torque wrenches this one's not a torque wrench we're
going to be using that one that's just a regular wrench but we've got a quarter inch torque wrench
and that is from 20 to 200 inch pounds the next one up is from 5 to 80 foot pounds the next one up
is 10 to 150 foot pounds and the last one that one right there is the half inch
and that is from 20 to 250 foot pounds so let's just take a look at the jig that i've made here
and uh explain how this all works so this is the jig here and all i really have is just two washers
and i've got a fastener now i picked all stainless steel but the threads go all the way you know like
all the way to the top so i got two washers and i've got three holes and i just topped them this
is a 3 8 piece of steel nothing fancy and i'm going to show you how this works because the
whole idea of verifying your torque wrench i've seen some people you know making videos where
they're hanging weights off it and scales and you know using all kinds of fancy methods the majority
of people who own a torque wrench own more than one because you can't actually do repairs or
anything like that without having a variance of torque wrenches you know quarter 3 8 and then
two half inch so i mean yeah you actually need all these torque wrenches you know for different
torques because not one torque wrench is good for everything i'll tell you that right now so
let's start right here and i'm going to use a perfect example of a video i just did a little
while ago where i was installing some spark plugs in a chevy cruze and i had mentioned
that i was using the torque wrench to install the spark plugs while i always use a torque
wrench to install spark plugs especially in aluminum heads and the torque rating was 18
foot pounds so how do you know your torque wrench can do 18 foot pounds so this one here well this
only goes up to uh 200 inch pounds which is 16.6 foot pounds can't use this this is no good these
two are the only two that qualify one starts at five foot pounds the other one starts at ten
now this one here will this actually work well it starts at 20. so you're really not going to
get 18 on that one are you so if you have two torque wrenches that can supply the torque needed
that's how this jig will verify whether your torque wrench is correct or not
so let's get to it okay so here's this fastener is not tightened this one's not tightened now
there is this one all we're going to do is the center one we're going to tighten down
to the target torque so we just put it on here and this one here is the 3 8
there it is clicking right there and that is at 18 foot pounds now we're gonna go three pounds
less for this one and three pounds more for that one so i'll bring it back when they're done
so we're back and the first torque wrench was a 3 8 torque wrench and that had the capability
of 5 to 80 foot pounds the next one is going to be the half inch torque wrench
and it's got a capability of 10 to 150 foot pounds so what we're going to do
is we're going to put it on the center one which is 18 foot pounds and see what happens
okay so you hear that click you know what that actually proves absolutely nothing
you don't know that could be a 200 pound click on there it could be an 80 pound torque it could be
anything right so that proves absolutely nothing and that's why the other two are so important
so this one here is 18 foot pounds and it clicked out this one here is three pounds higher at 21. so
this one started to move i would then go to this one but it didn't it clicked out so now we're
going to go to this one which is three pounds less at 15. this torque wrench it better move
so let's see if it moves you can see that moving now and then it clicked
out so you know that that torque wrench is in between 15 and 18.
so what's the odds of having two torque wrenches that are completely bogus the first one yes
it was 18. the second one it clicked out on the 18 and moved on the 15 foot pounds
so you know that it's in range now could you just imagine yourself you can actually verify
this even better by tightening up your tolerances and once you know you have a good solid torque
if you've got a torque wrench that's out of range well you can just recalibrate it yourself
can you see how easy this little hack is i mean all you need is just some fasteners now
i use stainless steel hardware only because i had it but this is uh just a 9 16 you know hex
head on the front it's a 3 8 diameter bolt you know coarse thread just a hunk of steel plate
through some paint on the front and that's it and you can see how easy it is that you
can verify whether the torque wrench you have is actually well it's accurate enough because the
tolerance is on torque wrenches yeah they're all over the map on you know generally i'm saying the
more money you spend on a torque wrench the better odds are that you're going to get a better torque
wrench how many times have you spent more money on something and uh realized that it was garbage
more times than often is when you spent less on something that you find out it's garbage well you
know none of these torque wrenches are expensive and they're all over 20 years old and yeah i've
had to recalibrate them i mean you know this is so easy it's a no-brainer anybody can do this
the only thing is you have to have another torque wrench in your series to actually
verify back and forth it's not perfect i'm not replacing you know all these fancy gears
that people have you know with uh you know two thousand dollar uh you know torque verifiers
i mean this is for your do-it-yourselfer quick and easy and that's what i like quick and easy thanks
