Do you have instructions and tightening torque for the ME DC contactor mechanical interlock?

We have no torque values or instructions concerning the mechanical interlock. Concerning the bush nut it our recommendation to tighten until you have lock washer compression and the arm is moving freely between the contactors.

This is in reference to part number 878D400G01 and 878D401G01 mechanical interlocks use for the ME DC Mill type contactors.
