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
DANGER
Make sure that all supplies for electrical
power, hydraulic pressure, and air pressure
are turned off.
Open the ball joint housings on the lower
arm and remove the DressPack.
Loosen the axis-2 lower arm metal clamp
and the axis-3 lower arm metal clamp loc-
ated on the inside of the lower arm by re-
moving the attachment screws.
Note
The screws are reached from outside the
lower arm!
