Action
Place a piece of wood (or similar) under
the arm house and lower the upper arm.
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 gearbox.
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.
