4.8.2 Replacing the axis-1 gearbox (IRB 6700 - 300/2.70, IRB 6700 - 245/3.00)
Action
With base and gearbox safely resting on the
support legs, unscrew the attachment screws
that secure the gearbox to the base, from
underneath the base.
Tip
This procedure is best performed by two
persons working together:
• one underneath the robot base making
sure that the bit is being fitted into the
screw head holes, all the way until they
reach the bottom
• one using the torque wrench, tighten-
ing the screws from beside the base.
Remove the protection tube from the base
by removing the two attachment screws and
pulling the tube downwards.
Fit two guide pins in opposite holes.
Tip
Lubricate the guide pins with some grease
to make the gearbox slide better.

92 kg (IRB 6700 -235/2.65, -205/2.80,
