Match the robot variant
Use the complete 3HAC044841-003 article with the IRB 6700 reach and execution record; do not identify the gearbox from the RV family name alone.
01
Product Overview
ABB RV-320E3 i=201 3HAC044841-003 is the axis-3 reduction gearbox listed for the ABB IRB 6700 robot family. It transfers the axis-3 motor torque through the robot's upper-arm drive train and forms the mechanical reduction stage at the axis-3 gearbox position.
In the IRB 6700 assembly, 3HAC044841-003 is the ABB Orange execution of the RV-320E3 gearbox. The spare-parts record distinguishes it from the graphite-white counterpart and associates the same gearbox family with the /2.60 and /2.85 reach variants.
Replacement planning for 3HAC044841-003 starts with the robot variant, axis position and gearbox execution. The service procedure keeps the cable harness fitted where possible, while the robot must be supported and the axis-3 mechanical interfaces restored before testing.

System Integration
Axis-3 drive position
3HAC044841-003 sits in the IRB 6700 axis-3 mechanical chain between the motor-side drive and the upper-arm structure. Its reduction stage must remain associated with the exact robot configuration and axis record.
Preserve the mechanical path
The gearbox carries axis-3 torque into the upper-arm mechanism. Keep the motor interface, bearing support and seals tied to the same installed position during service.
Keep the cable boundary clear
Because the replacement procedure can retain the cable harness, mark harness routing and connector positions before the gearbox is separated from the robot structure.

Installation Highlights
Controlled replacement
For 3HAC044841-003, the service sequence is a support-and-access task: prepare the work area, secure the robot, remove the upper-arm access parts, exchange the axis-3 gearbox, then restore sealing and calibration checks.
Prepare the work area
Provide the required floor space at the right side of the balancing device, with room for two pallets. Keep the foundation screws untouched while the robot is supported for service.
Support before separation
Support the upper arm and axis load before releasing the gearbox interface. Record the cable harness route and protect connectors while the mechanical parts are opened.
Restore the assembly
Fit the correct O-ring group, grease and rust preventive, reinstall covers and harness routing, then complete the prescribed calibration and motion checks before returning the robot to service.

Technical Questions
How can I confirm ABB 3HAC044841-003 for an IRB 6700 repair?
For 3HAC044841-003, confirm the axis-3 position, RV-320E3 ratio, ABB Orange execution and the robot's /2.60 or /2.85 reach record before ordering.
What should I check before lifting the upper arm for 3HAC044841-003?
With 3HAC044841-003, establish the service area and support the arm and balancing system first; do not release the gearbox interface while the axis load is unsupported.
Can the harness stay on the robot during ABB 3HAC044841-003 replacement?
The procedure for 3HAC044841-003 allows the cable harness to remain fitted or partly fitted when routing and connector protection are maintained during access.
Which sealing and service materials belong with 3HAC044841-003?
For 3HAC044841-003, plan the documented 3HAB3772-120 O-ring group for /2.60 or /2.85, grease 3HAC042536-001 and rust preventive 3HAC034903-001.
Why is the complete article string 3HAC044841-003 needed on a request?
3HAC044841-003 identifies the ratio, axis role and colour execution together, so the service record is not confused with the graphite-white 3HAC044841-002 counterpart.
What must be verified after installing ABB 3HAC044841-003?
After installing 3HAC044841-003, restore covers, seals and harness routing, then complete calibration and low-speed motion checks for the axis-3 mechanism.
