Cat D6 9u steering clutch throw out bearing nut torque

Anyone know what the torque is for the steering clutch throw out bearing nut or how the nut is kept in place so it doesn't loosen up? The is also the tool we make, 4 inch sprinkler pipe with metal tabs wielded inside with a 3 1/2 inch pipe wrench. We steaked it in the simi frozen ground (4, 5 inch bolts).
