Service Magazine SEPD1410, 15 March 2012, "New Torque Specification for the Self-Locking Nuts on the Rod As of the Stick Cylinders for Certain Excavators". Disregard this article. See the article that follows.Description of Change: There is an updated torque specification for the rod assembly self-locking nut used in the 315-3375 Stick Cylinder Gp. Increasing the torque specification for the self-locking nut prevents the stick cylinder from drifting. When the cylinder is stable, the rod assembly works as designed.Adaptable To: The new torque value for the 116-3516 Self-Locking Nut is 21000 1050 N m (15489 774 lb ft). This self-locking nut keeps the 315-3374 Rod As in place. Lubricate the threads on the self-locking nut with hydraulic oil before tightening. The updated torque specification is adaptable to the models listed above.
