Thread: Torque Wrenches

you could use a spanner and a spring balance or similar scale, just need to multiply the Force (F) by distance (d in metres), you can get F from the F=ma where m = mass as per the scales reading in kg, a=9.8 our answer will be in N.m

make sure that the scales are pulling on the spanner at a right angle.

Then again you could use armstrong method. Take normal torque wrench swing on it at a distance on the handle the same as the spanner you will use on the fan nut. Then try and apply the same force required to get the desired torque on the spanner a bit less repeatable but you should be somewhere near it.

yes you can get torque wrenches that fit over normal spanners.

I have seen an open end spanner attachment for a torque wrench, i think they are similar to a Crows Foot attachment but with a longer arm on them. probably be hard to find one though. I think the calibrated armstrong method would be your best option

As they are a Left Hand thread if you tighten it as best you can (without the Torque wrench and Crows foot type spanner), it should not come undone, I have never seen one come loose, Regards Frank.

Tank is right,the motor would have to run in reverse for it to come off.Just do it tight. Pat

It's good to know tho




My method is a bit cruder ...

Because the nut runs in reverse of the motor

.. and you can't get it off by trying to just undo it .. as the pulleys all turn ... and you get clamps and all sorts to stop them pulleys from moving





I always grease that fan nut

Method for off
So I get it undo via .. Put spanner on it .. grab my "nylon hammer" and give it 2 hits and its off

Method for tight
If it took 2 hits to get it off ... Then I give it THE SAME 2 hits to tighten it



Disclaimer

This is my method .... not recommended for anyone ... as I have to "judge if I have done it right"

It works, that's all you need, Regards Frank.
