Actually I know what it is, but I am not sure I am using it correctly.

I replaced a blade on my lawn mower, and I was trying to tighten the bolt to
spec, which is between 400 and 600 ft lbs. Well, I set my torque wrench to
500 ft lbs, and I was hoping to hear the "click" that tells me I got to
destination. But it's been a while since I used a torque wrench, and I am
not sure what I should be hearing anymore. Can you help? When I try to
give it another 1/4 turn I hear something, but it's not a full blown click.
Does this make sense? Yet, I don't want to go any further and overtighten
or even break something

For what it's worth, I was able to unscrew the bolt with the same setting on
the torque wrench. I am thinking that maybe this tells me that if I exerted
more or less the same force to unscrew it as I am in tightening the bolt ...
I should be okay.

Any help is appreciated.

Set the wrench to something real low (100?) and turn the bolt that has
been tightened to 500. The noise you hear should be the noise you expect ...

Check you specs again. 400 to 600 ft-lbs torque will shear off most any
bolt you'll find in a lawn mower. Is it 400 in-lbs?

You are right. The manual calls for "in lbs" not "ft lbs." As I look at

hundreds of foot lbs instead of (what it turns out to be) tens of foot lbs.

I think that 50 ft lbs is equal to 600 in lbs, which is the upper limit

it must be. even the nut on the back axle of a volkswagon is only like 180
foot pounds or something and you need serious power tools or a 10' steel rod
to get that.

Back it the fu*k down!...FULL SPEED REVERSE!
Is any of this sinkin' in yet? ( $1 Foghorn Leghorn )

OK, quick easy math he 480 in lbs = 40 ft lbs
You know..."480" as in "something nice and in the middle
of your suggested range."

Loosen it, re-tighten to 40 ft lbs. You'll hear the click.

I have heard that "click" before. Since I don't quite hear it now, and I am
scared to death that I may damage something, I am thinking of backing it
down to a lower setting first, as suggested by someone else.

Not necessarily true. Some torque wrenches require that you approach the
correct torque for the click to occur. If you have already exceeded it it
will never occur.

the bolt that holds on the blade on a lawnmower is nothing close to
500 lbs... its more like 80-100 ft. lbs... if you hear a noise when
cranking it up to 500 ft. lbs. its probably the bolt breaking........

500 ft-lbs doesn't sound that unbelievable. That's about the same torque as an

80-100 ft-lbs is like the torque on a car's wheel's nut; that's not enough for

No way is the spec anywhere near 400 foot pounds. With a 4 foot
handle, you would still need to exert a 100 pound force. You would
need to be a monster woman to get 400 foot pounds with a regular 1/2"
torque wrench with an 18" handle. The nut on the mower blade should
tightened to something like 40-50 foot-pounds.

To answer your question most just give a little "click" and that tells
you to stop pulling. en you don't pull any harder. You don't need a
torque wrench anyway. Take a 50 pound sack of anything and lift it
with one hand. If you can, use a 12 inch handled 1/2" socket wrench
on that nut and pull it as hard as you can with one hand. If you
can't lift a sack with one hand, then use two on the wrench.

Now that you have the right amount, set the wrench to 10 foot-pounds
and pull, you should hear a click. If it does click, move it up in
steps and keep listening for the click. If you don't hear the click
at 10 pound or 20 pound setings, then the torque wrench is most likely
ruined and not functioning. Just pull hard on it and you will get the
torque close enough.

Sure it is. More than enough. Tom
Someday, it'll all be over....

That's pretty high...
400 ft lbs is a lot.......
It will be a click....back off after you think you hear the click and pull
it up again slowly
to make sure it clicked

well read the original posters added on comments that he/she looked at

well at 500/12 = 41.6 lbs. of torque that is why his wrench clicked as
he easily reached the set torque... and i still stand by the statement
of 500 ft. lbs. of torque on a lawmower is way too much.... the flywheel
bolts on cars is only set at about 150 lbs. of torque... and that's

Yes, it does. 500 in-lbs is believable, but 500 ft-lbs is not.

No, it's about two to three times the torque on *anything* on a car.

80-100 ft-lbs is like the torque on a car's wheel's nut; that's not enough for

Nonsense. That's too much for a lawnmower blade, actually: the bolts are
smaller than wheel lugs on a car, and made of softer steel besides. For
mower blades, 40-60 ft-lbs is more like it; the spec on my John Deere STX-38
is 55, for example.

That may be a bit high for cars with aluminum-alloy wheels, too...

Not only that... the bolts that hold mower blades in place aren't all that
big. It's _physically_impossible_ to tighten one to 500 ft-lbs, because the
bolt would shear _long_ before it reached that torque.

You seem to be saying that if a bolt has already been tightened 50 foot
pounds and I put a torque wrench on it set to click at 30 foot pounds
and then start pulling on the wrench, I *won't* get a click when I reach
30 foot pounds of torque?

That would take a pretty smart wrench, wouldn't it?

Or, did you just miswrite what you meant to say?

On my torque wrench, if you ignore the click and keep pulling, it does not

It cannot detect an already overtorqued nut.

Sorry, I don't buy that. How does the torque wrench know the difference
between these two situations?

a) force applied to the handle is gradually being increased up to the set
point as the nut turns slowly, approaching the correct torque

b) force applied to the handle is gradually being increased up to the set
point as the nut remains stationary, having already been tightened beyond the
correct torque

What model of torque wrench is this, that is smart enough to tell the
difference between the two situations? You say that's how it works "according
to the instructions". Have you actually tested it, to see if that's how it
works _in_practice_? Please post the section of the instructions that
describes this amazing behavior.

I am finding out more about torque wrenches than I had intended. LOL Now
boys, keep the discussion civil, ok?

That could be the understatement of the century gt

Now boys, keep the discussion civil, ok?

Whole bunch of people on Usenet with not a whole lot to do, lots
of time on their hands, if'n you get my drift.

It's best to get in, get your answer, and bail out. Eventually,
this thread will spawn 1 or 2 flame wars and at least one
discussion of the election and the war in the middle east.

Run now while the gettin' is good!

Huh? Sure it will. If the nut doesn't turn (torqued higher than the
wrench is set for), the torque wrench clicks when your pull exceeds
the torque it is set for. Set a wrench for 50 foot pounds and pull on
a nut that is torqued any amount higher than 50 foot pounds and it
will click. The click tells you that the nut is torqued at or more
than 50 foot pounds.

Of course you are right, the click doesn't tell you anything about the
torque of the nut, unless you keep setting the wrench higher and when
it finally moves the nut you know the torque WAS the previous setting.

she's talking about a mower blade, which oughta be pretty
heavy torque.

500 inch pounds -- that would be 500 divided by 12, which is
about 45, or so. Not near a calculator. 45 is believable for
a mower blade bolt.

Briggs tends to be on with a 9/16 bolt head (what's that,
like 3/8-16?) and so that's doable.

Tecumseh tend to be a larger nut (15/16?) and that might go
more like 75 ft pounds, my guess.

If your torque wrench had a 2 foot
handle (which I doubt) it would take 250 lb. of force to get
500 ft.
lb. of torque.

Are you sure it isn't 500 INCH pounds??

It is an inch pound torque wrench and yes, unfortunately it was tested by
overtorquing and ruining a bunch of expensive fasteners that were already
past the measurement point due to an unsupervised inexperienced worker. I
didn't consider it a feature..... I considered it a design flaw..... but I
guess from an engineers point of view it is a feature since the torque
wrench cannot be blamed for the mis-measurement and over torquing. Lack of
proper use caused the problem. It was made by SK Handtool Corporation
http://www.skhandtool.com/ though I don't see the exact model in their
on-line catalog. It is 2 years old. Just dug it out of my garage so I
could answer your post. The instruction explicitly say to never torque a
fastener that is already tightened. Loosen it first. In our experience if
you don't do that with this model wrench it will never click.

Did you ever try that with a new one, that hadn't been abused?

It is working exactly as designed. If you tighten the item with it it
clicks when torqued correctly. If the item is already overtightened it is
useless as it should be. It is designed to get you to the correct torque.
It is not designed to tell you that the fastener is torqued greater than it
was supposed to be.
