Title: torque settings for hub nuts
Post by: a-ton on 24 August 2010, 15:43:11
Does anybody know what the torque settings are for the front hub nuts on 2.6 2001 please?

240nm

Isn't it 320nm?

I'm sure it's 320 Nm

very, very tight !

IIRC its just over my largest torque wrench setting which is 310nm

Yep its 320Nm - scaffold pole tight  :y

Oooops, 320nm. :-[

Just done one of mine not 10 mins ago, and yes 320 nm, but I don't have a torque wrench that big, so how many grunts to 320nm?

I got a feel for the leverage on the old one after backing it off and tightening a fraction at a time with the top half of a 3 ton trolly Jack handle on a large ratchet, best I could do.

Can I expect it to bed in and need a nip, or is it 320 job done? Mark seems to have a method for this if there is play on old ones by nipping the nut up a little, which I did twice on the one I just changed, maybe there is some feel involved.

....and what's Haynes on about with a plastic sleeve in the description?


Feels far better now anyway, knocking gone and smoother. :y

You can imagine the needed torque like this: 320 Nm is approximately 32 kilograms on a one meter lever. So, you'll need 64 kilograms on a 50 cm lever and so on... With a regular T-handle of your socket set (which is around 25 cm or so) you can stand on with one foot.

As result, the nut is as tight as one can get it with handtools

that can't be right :-/. 32 kg can be picked up with one hand, and placed on the end of a meter long lever isn't going to do much tightening. 320 Nm tight is ball breaking tight ..... the proverbial tighten till you fart - then another quater turn. ;)  ;)
320Nm in 'English' is 236lbft which uses the same method as yours ie 236 lbs on the end of a lever one foot long. That's going to equate to much much more than 36kg on a meter long bar.  :-/  :-/

Don't use Jimbob as a torque gauge though, his calibration is out. ;D ;D

One stain or two tight?  ;D

However.. if you do the maths, it really is 36Kg/m ..

236lb/ft would be roughly 78lb/yard, and if we assume a yard is more or less a metre (I know, it isn't quite) then you get 78lb/m.

2.2lb in a Kg, so 78/2.2 = 35.5Kg/m ..

It is very tight i know when Elite Pete did mine i think we went through two sockets snapping, and that was just getting the damn thing off :o

I was wondering the same while writing that but where am I wrong? 320 Nm is approx. 32 kpm, isn't it? I know the hub nuts are tight, my torque wrench is only up to 240Nm and I just tightened the nut as tight as I could get it.

....but how many grunts is that?

320nm = 1 fart. How many grunts to a fart though? needs to be accurate, i dont want to get to a fart suddenly then go to far...?

Nobody wants that.. that's called follow-through!  ;D

so let me get this straight, 236lb/ft and a lot of farting, yes? I'm just changing my discs and pads (after replacing the hub a couple of weeks ago hence torque setting) so may as well do it right.

As a matter of interest, whats the torque setting for wheel nuts.
