3.4.2 Changing the oil, axis 1 gearbox on floor mounted robotsFloor mounted or suspended robotDepending on whether the robot is floor mounted or suspended, the method ofchanging the oil differs.This section describes how to change the axis-1 gearbox oil in a floor mountedrobot. If the robot is suspended, see Changing the oil, axis-1 gearbox on suspendedrobots on page 158.Different versions of the gearboxThere are two different versions of the axis-1 and axis-2 gearboxes. The differentversions affect the mechanical structure of the base, frame and lower arm.Differences in the mechanical structure are pointed out in the procedure as validfor 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-12/1.65Further information about the differences are given in Non-compatible versions ofaxis-1 and axis-2 gearboxes on page 428.Location of oil plugsThe axis 1 gearbox is located between the frame and base of the robot.The oil plugs are 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-8/2.0xx0800000304Oil plug, filling and ventingAOil plug, draining, with sealing washerBContinues on next page150 Product manual - IRB 26003HAC035504-001 Revision: Q© Copyright 2009-2018 ABB.
