Gwilly has it in grunts, 80Nm is more or less 100-ft.lb or what you use to tighten car wheel nuts, that much. I've actually got a socket for the rear wheel brake plate, I most certainly did not get it for that, some special car job, and it was far from cheap. Over the years one tends to accrue odd tools :]

Melco box spanners come in a full range of Whitworth sizes.

Jefrs I don't know where you get 100ft.lb for wheel nuts from, that would risk shearing the studs on many small cars. I suspect you are mixing Newton Metres up with foot pounds.
100 foot lbs torque on a wheel nut it entering bus, coach, truck territory.

He got it Ar*e about face, I think Papa

There seems a lot of confusion in these answers - or am I the one confused!?



Why are we talking of EFI when ‘nig’ has a 350? The correct torque for the gearbox sprocket I believe is 47 ft/lbs. For wheel nuts 48 ft/lbs.



If ‘nig’ wanted to see the spanner then it is shown on our host’s excellent web site. He will also find a step-by-step technical note with plenty of pictures - only trying to help

Well, 100ft lbs is a lot for small car wheel nuts but some bigger cars ask for this sort of torque.
Bigger Volvos especially are over 100 and a lot of 4x4s are approaching this.

One of my other bikes (an MT09) has a factory specified rear wheel spindle nut torque of 108lbs/ft.

Unless the custom build fairies got to it overnight and carried out some serious modifications I don't think it quite falls within the category of bus, coach or truck just yet.

Ric, that is a specified torque for a particular motorcycle, the rear wheel bolt torque on my K75S BMW is 78ft lbs.
My point is that 100 ft lbs is far above that specified for most car wheel nuts and would snap the studs.
Wheel nut/bolt torque is something you really do need to know for each motorcycle/vehicle you own.
