Wheelnut torques
Having just purchased a 1/2inch torque wrench thought I'd try it out on what I bought it for... checking the wheel nuts.
Backing one off then torquing to 140NM (is this correct?... from memory from earlier posts) seems really NOT tight. Doesn't take as much turning force to undo as I would have thought.
The nuts are obviously well over the 140NM, done by the tyre fitter when all four were replaced last year, but appreciate that they might overtighten them.
So is 140NM correct? Doesn't seem very tight IMO.

140Nm is def correct. Is your wrench calibrated (the Halfords Pro Advance ones are)
You need to undo them all, re-torque them, then drive a few miles, then check again. Bodsys Brake Bible

Well, it's probably not the best in the world, it's a Draper. Got good reviews on Amazon, someone checked theirs against a calibrated one and it was only a shade out. I'd assume it would have been calibrated of sorts when it left the factory.

Your not alone,ive recently bought a "calibrated" torque wrench,so tightened my wheel nuts to 140 n/m when I swapped my rims over & also thought that it doesn't feel very tight Www.devonchilliman.co.uk

Perhaps just worrying about nothing.
When doing wheel nuts in the past I usually tighten them up as much as I can (got one - actually three - of those extendable handle thingies), so may be they were overtight.
Just nowhere near as tight as the professional tyre fitters. And they must be correctly done. Surely?

In the scheme of things 140 Nm is a pretty high torque setting. Don't try such a high figure on an ordinary car!

Yeah I know, it took ages to wind the handle around to 140! but it doesn't take that much force to undo the nut though. That's what got me wonering if everything was okay.

all torque
If I remember correctly my old 101 was only 70Nm.. I can almost get that with a gerber It is better to have and not need it then need and not have it.

Nick,
It sounds like you are still a bit concerned with the calibration of your torque wrench compared to what feels right. Presuming you don't have access to a calibration tool (few of us do) have you tried borrowing another torque wrench and doing a comparison?
I have 4 torque wrenches and one of them is a Draper (albeit a small one not suitable for a D3), but it still came with a cal certificate hidden in the paperwork.Land Rover - Turning Drivers into Mechanics Since 1948

Robbie,
Nice avatar
I have a 3/8" torque wrench, which was 'free' with a socket set years ago. I checket the two against each other this morning. They both seemed about the same. Will try the experiment again though later on.

Thank-you, it was your post that prompted its return - it's from my Pillow Torque collection. Land Rover - Turning Drivers into Mechanics Since 1948
