I can't find a setting for the large nut on the end of the axle, holding the hub on, is there one? If so anyone know what it is please?

Don' think there ever was a torque spec for it. Just tighten it up good and bend the locking tab over.
As it's only a thin nut I would be careful to not overtighten it.
Of course if you're using Roy's method of a hammer and chisel I'm not sure how you would convert that to a torque setting value.

Les, here are a few more useful comments at the end of this thread

think i remember somewhere 50lb

Yes - 3 or 4 hefty clouts with a 'wee heavy' hammer is fine - basically till it stops going round.....

-----or until the nut has had all flats rounded off! Anyone want a redundant heavy duty socket.

Do the job properly and Invest in the correct socket.
If I had used a hammer and chisel on the hub nut my old foreman Archie Haydon (and under whose tutelage I served my apprenticeship) would have kicked my a--e all the way to the workshop door
Looks as though the one used by Les may be for sale.

So what is the correct size socket?

Dunno - I have a big open ender somewhere that fits..

The socket size required is 1 & 7/8" AF.
Could only get that size in 3/4" drive so have to use an a 1/2" to 3/4" adaptor.
Because the hub nut is so narrow/thin I have ground down the nut face of the socket so that all of the socket is engaged with the nut. Normally the socket would have a inside chamfer so reducing its effectiveness.

ah the rear hub nut dohhhhhhhhh

Rog says "This is actually 1 & 1/8 Whitworth but 1& 7/8 AF is a good fit", see

I have a 1 & 7/8 AF ground down as per Philthehill's suggestion, it works but it is a little lose.... so perhaps the Whitworth is the correct one...

My socket is marked 1 1/8 whit.

My 1 & 7/8" AF socket is a relatively tight fit on the nut and is not loose at all. And yes it is marked 1 & 7/8".
Grinding down the socket to remove that inner chamfer makes all the difference to the fit of the socket on the nut.

Yes I had to do that, reluctantly though, as it was/is a sturdy 3/4drive Britool. There again can't think of another use for it!

I suggest you try and get a 6 sided socket, it will be a better fit.

I have a 12 sided one which would explain the slight looseness

Thanks Phil, I do have an older 1&7/8 AF socket that I'll have to look at, I was thinking that it's 1/2" drive but it's more than likely a 3/4" drive. No problem, as I also have a 3/4 drive ratchet, a johnson bar and a torque wrench.
FWIW, it looks like 48mm would be a close fit

48.5mm AF to be exact.
I have just measured the socket to be absolutely certain.

Can you pleas describe what a Johnson bar is? Over here if it is the same we call them breaker bars

Phil, a Johnson bar is what I was taught to call it many moons ago, the yankee's call it a breaker bar, so I guess that's the same as what you're calling a breaker bar.
A lot of our "Canadian" English is slowly (or maybe not so slowly) being changed to "American" English. We used to call small trucks a "1/2 ton" or a "3/4 ton", now they're all "pickups". We used to have chips, as in fish and chips, now they're "fries".
48.5mm AF, now that's an odd size socket.

Katy
Many thanks for the breaker bar description. It is as I thought.
Yes the 48.5 is an od measurement but that is what the 1 7/8" A/F socket measures between the flats.
Pickups/small trucks in Aussi land are called Utes (utilities).
Language who would have it.
