Torque setting of Norton oil pump worm drive nut

[Red Gauntlet]

Just trying to find the torque setting for the timing shaft cam worm drive nut on the Norton engined G80CS, according to Norton it should be 15ft-lb on the Commando so a good start point. Cannot find it in any of the Matchless manuals, but maybe I have missed it?

(Oil pump worm gear/nut (06-7889, LH thread, on end of crankshaft) 15 ft-lb)

[g80csp11]
