Advice on wheel nut torque. The only problem is I've not yet found published advice on the correct torque for the old type conical wheel nuts!

That was the old method. Somewhere in my collection of stuff I've got a manual for the AEC 7.7 engine. Look in the section of cylinder head stud torque and you see a picture of a worker in brown dust jacket with statutory cloth cap and roll-up leaning on a scaffold bar through the cab door of a Matador showing you how tight they should be!!

The best I can offer is from various Arriva RMs I've seen which have stickers over the wheel arches which say something like 480lb/ft, but I'm open to correction on that figure.

But otherwise, yes, a long scaffold bar, go tight, then when the nut cracks it's tight enough! Not recommended for today's elfensafetea culture though.

Talking to an ex police traffic accident investigator, he went to a tipper truck on the Eltham by-pass which had sheared several wheel nuts. The driver was asked if he ever checked the wheel nuts for tightness. "Yes, every day". "Well, what do you do?" "I put the wheel brace on and lead on the bar till the wheel nut cracks". In effect greatly over-tightening the nuts until the studs broke.
