Firstly sorry I have asked this question a while back and forgot the answer.

I need to adjust the kickdown band on my torqueflight auto box.
The manual says torque it to 72 inch pounds and then slacken off 2 turns.
My problem is I can't find any local hire firms that have a inch pound wrench.
I have a foot pound wrench. I think that 72 inch pounds equates to 6 foot pounds but most ft pound wrenches don't go as low as 6 ft pound and even if they did they are very big and clumsy to set such a delicate setting.
If I put a foot long bar on the adjuster and pull a set of fishing scales to 6 pound would this work and would it be accurate?

any help appreciated

Why? surely if your having trouble with a wrench that don't go that low you convert to match a wrench that does,

if you use a bar 1 ft long and apply a 6lb pull on the end wont that multiply it by 12, 12 x 6 = 72lbft ??
surely a 6in bar given a pull of 1 lb on the end will give 6lbft ??????? :beuj:

Paul, thanks for the offer.
Morecubes, thanks for your kind offer, subject to the planes flying again I am away for two weeks on thursday but will probably take you up on your offer when I come back.

Chris32, for curosity I would still be interested to know the definative calculation for using the spring and bar method. Any engineers out there to solve this for us?

Nope cos you are measuring in lbs per foot, to get it to multiply by 12 you'd have to be measuring in lbs per inch ( or something like that ).
The poundage applied can be meaured anywhere and is calculated into the figure ie tightening torque is 72 lbs per foot or 142 lbs per 6 inches etc etc It's the poundage applied at the set length rather than the actual turning torque .
