MG MGF Technical - Let's torque it over...

Hi, all,

Does anyone know the correct torque at which to set the centre hub nut (rear)?

Ta,
Col

PS This would make a handy addition to folks with their own DIY-related websites: a table of the correct torque settings for the most common jobs. Tony, Dieter, Rob, SF?

PPS Sorry for the thread title ;-)

LOL Col! ;oD

Anyway, yes, I've been thinking of doing exactly as you suggested... If I get time, I'll work on it and get something on line soon.

Just checked my workshop manual. Oddly, the rear hub nut is not listed (!!!) - but I assume it to be the same as the front? 210Nm

Anyone able to confirm?
Rob Bell

While we're torqueing about this, what range is best for the F. In that I mean, I bought a 3/8's drive torque wrench from stoneleigh at the weekend, but it goes from 10-80Nm. I only got this as all my sockets are 3/8's so they would fit, i nearly got a 1/2" drive which ranged from 80-240Nm (I think). Am I now going to have to go and buy another one for the higher numbers or are there very few applications on the F that require the higher setting.

Forgive me if this is a stupid question but I am rather new to having to use torque settings, most of my DIY has been done around the house in the past rather than the car.

Very tight

Phil,

I'm new to this torque business too. I actually *did* buy a 1/2" drive, then had to go back to the shop to get a 1/2"-3/8" adapter for my 'basic' socket set. Doh!

Indeed, I also needed a 3/8"-1/2" adapter 'cause the new (Draper) torque wrench said not use it for UNscrewing (for fear of decalibrating it I believe) and the 1 1/4" socket for the hub nut is 1/2".

Rambling, rambling.

On my travels around the web (which lead to my question above), the hub nut is the highest I've seen. The next highest (I've come across) is 85Nm for the rear-brake-carrier-to-the-hub bolts.

Rob, you've got the bible, educate the great unwashed ;-)

Stephen, are you the fella with the silver F that tears down the fast lane of the Navan road into Dublin every morning?
Colin McIlwaine

D'oh, a 1/2" to 3/8" adapter. Now why didn't I think of that? (_8(I)
Phil Brindley (Work)

80Nm is very tight, usually head bolts require this type of torque, but for the k its some low value (30?) and then 360degrees(?) extra for which you need a breaker bar, not a torque wrench.

The pig of a nut is the one on the end of the crank, which hold on the cam belt pully and alternator pully, this one is a stunning 210Nm!!!
Will Munns

Colin no I am not the afore mentioned gentleman who tears down the Navan road. I am in the North though a break down South would be welcome.

Anyway I have a workshop manual at home and will check this torque setting if it's in it. I know I will be damned for saying this but I didn't use my Torque wrench on my front hubs over a year ago and they are still there.
S Laithwaite

Oh and rule of thumb for torque (unless specified) is how much pressure would a reasonable person put on a spanner to fit the same bolt (think 8mm spanner length vs 17mm spanner length) It's too easy to forget this when all the sockets fit on the same ratchet!!
Will Munns

Okay, I can take a hint !

Torque settings are now up.............

Excellent Tony. Thanks for that. I'm sure that will prove to be most useful to us all.

And. Woo Hoo, my little wrench will cover most of those settings :ŹD
Phil Brindley

Nice job, Tony.

Okay, I'm still really sorry ;-)
