ABB 3HAC061403-001 Replacement Gearbox for IRB 6700

Product Overview

ABB 3HAC061403-001 Replacement Gearbox for IRB 6700 — Seamless Axis 3 Upgrade Solution

The ABB 3HAC061403-001 is the OEM-specified TS225R precision reducer (gearbox) for Axis 3 of the ABB IRB 6700 series industrial robot. This component is a critical mechanical transmission element responsible for converting high-speed motor output into the precise, high-torque rotational motion required for reliable Axis 3 articulation in heavy-payload robotic applications including automotive body welding, press tending, material handling, and palletizing.

At TOPNLMS, we supply the 3HAC061403-001 as a direct drop-in replacement for worn, damaged, or end-of-life gearbox assemblies on IRB 6700 robots currently in production. Our stock is sourced from authorized ABB distribution channels and verified against ABB’s mechanical specification sheets prior to dispatch. Each unit ships with full dimensional inspection records and is backed by a 12-month warranty.

Seamless Upgrade Solutions

A successful Axis 3 gearbox replacement on the IRB 6700 is rarely a single-component operation. In practice, field engineers undertaking this repair also inspect and often replace adjacent components to restore full robot performance and extend the maintenance interval. The 3HAC061403-001 gearbox replacement is most commonly performed alongside the following components:

The ABB 3HAC044075-001 motor unit for Axis 3 is frequently replaced in tandem when motor bearing wear or winding degradation is detected during gearbox disassembly — replacing both simultaneously eliminates a second planned downtime event within 6–12 months. Similarly, the 3HAC026253-001 Axis 3 motor cable harness should be inspected for insulation fatigue and connector corrosion at the time of gearbox removal, as cable routing passes through the same joint housing.

The ABB 3HAC14178-1 SMB (Serial Measurement Board) and its associated resolver cables — including the 3HAC031683-001 resolver cable set — are critical to post-replacement calibration accuracy. If the SMB has accumulated resolver drift errors or fault codes prior to the gearbox failure, replacement of the SMB alongside the gearbox ensures a clean calibration baseline using the IRC5 controller’s fine calibration routine.

For robots operating in environments with high contamination risk, the 3HAC028357-001 Axis 3 sealing kit provides the O-rings, lip seals, and gaskets required to restore IP67 ingress protection at the gearbox joint after reassembly. Omitting this step is a common cause of premature grease contamination and repeat gearbox failure within 18 months.

Where the IRB 6700 is integrated into a production cell controlled via PROFINET or EtherNet/IP, the ABB DSQC688 fieldbus adapter module installed in the IRC5 controller cabinet should be verified for firmware compatibility with the robot’s RobotWare version before returning the cell to automatic mode. In older IRC5 cabinets, the DSQC679 teach pendant and its USB service port are used to upload the updated calibration offsets generated after gearbox replacement.

Finally, for facilities maintaining a local spare parts inventory, stocking the 3HAC061404-001 Axis 4 gearbox alongside the Axis 3 unit is a common practice among maintenance planners, as both axes share similar service intervals on high-cycle IRB 6700 installations and can be replaced during the same planned shutdown window to maximize uptime between maintenance events.

Retrofit Guidance FAQ

Q: Is the 3HAC061403-001 a direct bolt-on replacement with no mechanical modification?
A: Yes. The 3HAC061403-001 uses the identical OEM flange pattern, shaft dimensions, and mounting bolt circle as the original Axis 3 gearbox. No machining, adapter plates, or custom tooling are required beyond ABB’s standard IRB 6700 maintenance toolkit.

Q: Does replacing the Axis 3 gearbox require a full robot recalibration?
A: Yes. Any gearbox replacement on the IRB 6700 requires a full axis calibration. ABB recommends using the CalibWare software routine via the IRC5 FlexPendant or the fine calibration procedure documented in ABB Product Manual 3HAC032140-001. Calibration marks on the robot arm must be used to restore the reference position before running the calibration routine.

Q: What lubrication is pre-filled in the replacement gearbox?
A: The 3HAC061403-001 is supplied pre-filled with ABB-specified grease conforming to the TS225R lubrication requirement. No additional grease is required at installation. Follow ABB’s grease replenishment schedule (typically every 10,000 operating hours or 2 years, whichever comes first) for ongoing maintenance.

Q: Can this gearbox be used on all IRB 6700 payload variants?
A: The 3HAC061403-001 is specified for the IRB 6700 series. Confirm your specific robot’s article number (e.g., IRB 6700-235/2.65, IRB 6700-200/2.60, IRB 6700-155/2.85) against ABB’s spare parts catalog or contact TOPNLMS with your robot’s serial number for confirmation before ordering.

Q: What is the typical lead time and shipping method?
A: In-stock units ship within 1–3 business days from Xiamen, China via DHL Express, FedEx International Priority, or sea freight depending on order quantity and destination. Express delivery to most destinations in Asia, Europe, and North America is 3–7 business days. Contact us for freight quotes on multi-unit orders.

Q: Is the unit tested before shipment?
A: Yes. Each 3HAC061403-001 unit undergoes dimensional inspection and visual quality verification before dispatch. Units are packed in OEM-style protective packaging with foam cushioning to prevent transit damage to the precision reducer internals.

Warranty Assurance

Every ABB 3HAC061403-001 supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. This warranty covers manufacturing defects, premature mechanical failure under normal operating conditions, and dimensional non-conformance to ABB’s published specifications.
