3.3 Inspection activities
3.3.1 Inspecting oil level, axis-1 gearbox
Different versions of the gearbox
There are two different versions of the axis-1 and axis-2 gearboxes. The different
versions affect the mechanical structure of the base, frame and lower arm.
Differences in the mechanical structure are pointed out in the procedure as valid
for different robot version:
• IRB 2600-20/1.65, IRB 2600-12/1.65, IRB 2600-12/1.85, IRB 2600ID-15/1.85,
IRB 2600ID-8/2.0
• IRB 2600 Type C-20/1.65, IRB 2600 Type C-12/1.65
Further information about the differences are given in Non-compatible versions of
axis-1 and axis-2 gearboxes on page 428 .
Mounting position of the robot
If the robot is floor mounted, follow the procedures in Inspecting oil level, axis-1
gearbox (floor mounted) on page 121 .
If the robot is suspended, follow the procedures in Inspecting oil level, axis-1
gearbox (suspended robot) on page 122 .
Location of oil plugs (floor mounted)
The axis 1 gearbox is located between the frame and base of the robot. The oil
plug for inspection is shown in the figure.
IRB 2600-20/1.65, IRB 2600-12/1.65, IRB 2600-12/1.85, IRB 2600ID-15/1.85, IRB 2600ID-8/2.0
