Technical JH williams torque wrench

I just bought A JH williams S-57 torque wrench and was wondering if anyone could tell me how it works. I need to torque A balancer bolt on A buick 430 to 200ft pounds. The wrench goes from 20 to 200.

 

Interesting wrench. I've never seen one.

but a little googling, gives us, from garagejournal:

Do you want to use it as a sight reading or a sound reading torque wrench?

Using it visually, you just read the torque off the scale and the edge below it. I use mine in this mode most of the time.

To use the sound reading, the bottom screw has a riser under it that is moved up to raise the torque arm. Then button on the end of the long wire rides up next to the scale. The upper set screw is used to adjust to th torque reading along the scale. In use the button will make a sound when the torque reading set is reached.

 

Hey thanks for the information, I would like to use it on the sound reading. It would probably be hard to look at the gauge trying to go for 200ft pounds,that is the torque specs on the bolt that needs torqued.
I bought this wrench off of Ebay, its hard to find one that goes to 200.I have A craftsmen beam and clicker type but they only go to 150ft pounds.

 

I got one of these.

They need to be calibrated every so often. Your's looks older and shows signs of use plus it came from e-bay. It will probably cost $60. for shipping and calibration.
Squirrel's looks good at that price. Just sayin'

 

I would probably torque to 150 lbs. with your current wrench and check your newly acquired wrench
against that.
Then you should know how to set your new one to 200 lbs.
Just my thoughts.

 

I'm not sure you can calibrate a beam type torque wrench, which is what the Williams is.

Clicker types do need to be checked regularly.

 

Saw this the other day. Its high on my priority list of "must have" tools!

 

Much as I hate to say it, the HF Icon torque wrenches outperformed Snapon in a test I saw recently.

I hate buying Chinese these days, but I hate paying rip off prices even more..... (PS I have a Snap On torque wrench, but I got it for free)

 

What’s the accuracy range of a beam wrench? Clickers are best used between 20-80% of the range for accuracy. Same for beams?

 

Torque wrenches are only as good as the operator.

 

I've found the better brands a beam type wrenches to be highly accurate, provided they haven't been abused.
I have several different types and sizes of torque wrenches, beam, click and dial. For higher accuracy, it's best not to use any type torque wrench at it's higher settings to achieve the desired torque. Best to use a bigger wrench on it's lower range of settings than a small wrench on it's higher settings. When I have to torque something at say 200#'s, I use a torque multiplier. This one is 4 to 1, so setting the torque wrench at 50# will yield 200# with the multiplier. It's a more accurate(and safer) method of achieving high torque settings than using the higher torque wrench settings to get there. My 2 cents....

 

I was told by the guy that calibrated my torque wrenches that you don't want to use the top or bottom 10% of their scale as accuracy will suffer, particularly at the top of the scale. You'll also risk damaging the wrench.
