Action
Secure the tubular shaft unit with round-
slings in an overhead crane.
CAUTION
Prevent the slings from sliding!
For example a small plate can be fitted to
the lower attachment hole for the cable
bracket (removed in a previous step). The
plate should be fitted so it points down-
wards and functions as a mechanical stop
for the roundsling.
At the other end of the tubular shaft unit, a
shackle can be fitted if the wrist unit is re-
moved.
Remove the attachment screws that secure
the tubular shaft unit.
Remove the tubular shaft unit using caution.
The tubular shaft unit is fitted with Loctite.
CAUTION
Do not damage the gears when removing
the tubular shaft unit.
CAUTION
Remaining oil will drain out from the gear-
box cavity when the tubular shaft is lifted
out.
Action
DANGER
Turn off all:
•
electric power supply
•
hydraulic pressure supply
•
air pressure supply
to the robot, before entering the robot
working area.
Remove residues of old Loctite and other
contaminations from the assembly surfaces.
Remove any painting from the assembly
surfaces, with a knife.
