Couple of our tech's replaced a M-20iA Joint 5/6 wrist assembly last week. (this robot has the through the wrist tube) We let it sit over the weekend and we are seeing some oil weeping out where the assembly is bolted to the Joint 4 casting (Fanuc Doc. says Joint 3). They cleaned the surfaces and applied the Loctite as instructed from the manual. Let it sit overnight before adding oil, etc. We didn't get to the exercise portion where we move the axes and then check the pressure. It only moved from the Mastering position down to the home position.
Are there any tips/tricks for performing this task? We are going to redo it tomorrow and was hoping one of the Fanuc expert tech's here had some insights. Thanks.
