Note
Keeping the cable harness and DressPack fitted on the robot during gearbox
replacement is only a recommendation. If it is not possible to put the lower and
upper arm close enough to the robot, the cable harness and DressPack in the
base and in the frame must be removed first.
1 If installed in an inverted position (option 3317-1): Lift down the robot to floor
standing and secure to the foundation.
2 Drain the axis-2 gearbox.
3 Loosen the cabling brackets inside the lower arm and on the frame.
4 Remove the upper and lower arm mounted together, as an assembly.
5 Remove the axis-2 motor.
6 Replace the axis-2 gearbox.
