3HAC058991-003 and 3HAC058991-004 combines the motor and pinion under one documented IRB 660 spare-item role.
The finish mapping gives maintenance and procurement teams a visible way to preserve the correct ABB order configuration.
Axis position, robot identification and calibration impact still need to be recorded before the assembly is released to an outage.
The ABB 3HAC058991-003 and 3HAC058991-004 selection covers a motor including pinion documented for axes 2 and 3 of the IRB 660. ABB assigns the first listed Product ID to the ABB Orange finish and the second to Graphite White.
For joint-drive service, 3HAC058991-003 and 3HAC058991-004 keeps the motor and pinion within one documented spare assembly. The installed axis and finish remain part of the configuration identity even though both entries share the same base digits and service role.
Before ordering 3HAC058991-003 and 3HAC058991-004, compare the motor label, finish, IRB 660 serial record and axis position with the approved spare-parts documentation. When replacement affects resolver values or calibration position, complete the applicable ABB calibration and guarded verification procedure before production motion.
