Action
This step is only valid when the upper arm
is removed due to replacement of the axis-
3 gearbox:
Place pieces of wood (or similar) under arm
house and wrist. Lower the upper arm, and
let the upper arm rest as shown in the fig-
ure.
This is done in order to keep the axis-3
gearbox in a vertical position and to get the
best position to replace the axis-3 gearbox,
if applicable.
Action
Remove two attachment screws in opposite
holes and replace them with guide pins.
Tip
Lubricate the guide pins with some grease
to make the gearbox slide better.
Remove all but one of the remaining attach-
ment screws.
Fit three fully threaded screws and use
them as removal tools.
Remove the remaining attachment screw.
