Thanks!

I think its 1 15/16 AF if your lucky like me you can borrow one off a neighbour with a Land Rover!

By the way one side is a left hand thread. The left one I think , but someone will be along soon to say which one. I'm sure its really a BSF size, but big nuts are more forgiving when it comes to a miss match.

Here you are

I stand corrected!

Ideal, thanks!

Yes, it's the left hand side that has the left hand thread.

And for many years - a hammer and chisel has been the method for this nut!

Bit drastic isnt it?

Oh and one more thing, my mog appears to have 7 leaf springs, not 5. Has someone put on a pair of traveller springs?

cheers,

Yes - 7 leaf are Traveller - helps to minimise the axle tramp - but of course slightly harsher ride if running empty. The hub nuts are not meant to be all that tight - firm tap with chisel gets them going - then spin off by hand.

I'd still use a spanner if you can get hold of one. If you happen to be a bit further north, I've got one you can borrow.

Oh if you have the right spanner - use it of course!

the early Minor saloons had 7 leaf springs - later on they changed the spring design to give the same rating with 5 leafs (and used uprated 7 leafs for the travellers)

Hammer and chisel isn't actually that drastic. It's a very fine thread on a big nut so it works easily. Obviously use the correct tool if you have it but if not it can be done without.

Ah, that might explain it then. My mog is an early model!

It will be a miracle if it's still on the original springs!

It is very likely it is, theres no mention of spring replacement in the service history.......most of the vouchers in the BMC voucher book are still there as well. I know for a fact that the original owner (who had it from 1957 to 1998) was a complete mechanical novice and always took it to the same garage, even if it just had a damp distributor or something!!

My 1957 car had the original 7 leaf springs and when they needed replacing I fitted the five leaf type which greatly improved the ride comfort.
My teeth are still original as a result!

I've just had mine done on the left side ie. a new wheel bearing kit. The old bearing was fine, it was the inner seal that was leaking so it seemed like a good idea just to replace the whole assembly....and yes, the mechanic used a hammer & chisel because he hadn't a spanner or socket that fitted. I wish I could have known about the LH thread, though...would have saved a few choice swear-words.
