Differential Locking ring (Diff Overhaul)

Hi Guys, can anybody tell me how tight the Diff Locking Ring needs to be? I'm overhauling the diff, but cant find any info on the torque setting.

Its item number 3 in this diagram

you pull up bearing caps 2 x bolt each ,start adjusting nut on both sides ,adjust one on the side nearest crown wheel ,till all backlash between crown wheel and pinion has gone line up rool pin or locking tab by going a little further, adjust other side till backlash of 4-7 thou or .10mm-.17mm is achieved, remove and loctite 1 bolt at a time on each cap leaving other nipped uptorque to 82 nm 6o lbsft

Perfect, Cheers James
