Folks,
Regarding the rear axle and the large nut which holds the bearing carrier onto the axle tube - one side LH thread and the other RH thread (on later cars) - yes the one some folks mat have tightened / removed with a hammer and chisel! I can find no mention of torque setting in my workshop manual.
Does any-one have a value / reference?

As it is a "special" 8-sided nut you need to use a special socket to remove/tighten it. I canĀ“t connect a torque wrench to my 8-sided socket, so I did it as tight as I can. I did many axles in the past and no problems so far. Its like with the Mini front axle centre nut. Roger Menadue once said: "Tighten the nut as hard as you can till the spanner breaks."

Josef, I have appropriate 2 13/64ths AF Octagon socket and an adaptor which allows the drive of the torque wrench to fit... The unknown is just the torque setting.

The original Churchill tool just has a 1/2" round bar to tighten the nut. It's about 18" long. How much torque can you apply with that ? - enuff !

The MGAGURU site link from the above BCF thread, has the info required circa 150 lb. ft. Sq. mgaguru.com/mgtech/rearaxle/ra102.htmNow this is hugely above the 18" bar capability. It might be a moot point but getting to this limit requires an 'extension' to be fitted to the torque wrench (think cut down scaffold pole) or a rather large intake of spinach! The other problem is keeping the socket straight on what is a wide thin nut. I think I may end up with Josef's suggestion of getting as tight as I can with the longest lever I can both use whilst holding the socket tight and straight in the nut

You need a proper socket like this from DWM www.bighealey.co.uk/axle-3/socket-bn2-bj8-axle-rax235freeimagehost

Well after my porridge this morning, I tightened it an much as I could with the biggest lever I had, and that will have to do. The lock washer has been folded down (nice and tight) over one of the flats, so it isn't going to be going anywhere in a hurry!.

I've never worried about torque setting of this nut. Considering many folk have fitted it with the aid of a hammer and chisel.
I have the correct tool so I do it "nice and tight"
