I will give you what I have from a Mk IV manual.... Nut, layshaft securing....16-18 kgm or 115-130 ft/lbs. Nut, layshaft safety.......7-7 kgm or 50-57 ft/lbs. These appear to be the items you want.. There is a torque table on pg. 33 with no real info that these are what you want. Add LocTite blue to these nuts also. HTH
