More Information

Overview Manuals Axis-4 Access Seal Control Calibration Path Product Applications

Features:

  • Fourth-axis identity: ABB assigns the complete article number to IRB 6700 axis 4
  • Combined drive scope: the spare description includes both rotating AC motor and pinion
  • Arm-mounted service: ABB provides a dedicated axis-4 motor replacement procedure
3HAC043456-003 identifies the IRB 6700 fourth-axis drive assembly rather than a general robot motor.

Its pinion-inclusive scope matters when receiving teams compare the delivered assembly with a motor-only offer.

ABB places sealing, leak testing, and recalibration within the completion path for this arm-mounted motor.

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Service position: axis 2 is set to -65° before motor work
  • Upper-arm position: a vertical upper arm can remove the need to drain the axis-4 gearbox
  • Fallback: drain the axis-4 gearbox when the required arm position cannot be reached
  • Motor-cover seal: ABB lists circular and hexagonal O-ring profiles
  • Flange seal: the motor flange uses a separate O-ring
  • Profile matching: a replacement cover O-ring must match the profile already installed
  • Closure: damaged gaskets or O-rings are replaced before the cover is secured
  • Reference route: existing or newly created axis reference values are used after repair
  • Fine calibration: external cable packages and tools must be removed
  • Completion: the robot is recalibrated before the first controlled test run
  • IRB 6700 axis-4 repair: restore the documented fourth-axis motor-and-pinion position
  • Arm-drive overhaul: manage removal, sealing, pinion engagement, and leak testing under one ABB service procedure
  • Calibration-led recovery: return the repaired axis to service using the applicable ABB calibration route
Description
3HAC043456-003 is ABB's rotating AC motor including pinion for axis 4 of the IRB 6700. Its complete article number separates the fourth-axis assembly from the closely related axis-5 configuration.

Within an arm-drive repair, 3HAC043456-003 combines the motor and pinion under one spare reference. ABB's axis-4 procedure treats motor removal, pinion engagement, sealing, leak testing, and calibration as one controlled service sequence.

A work order for 3HAC043456-003 should retain the robot identity, axis-4 fault history, installed sealing profile, calibration route, and motor-cover condition. These records define the parts and service steps needed to return the fourth axis to operation.
Alternative Names

Technical notes
3HAC043456-003 must be refitted with the cable-gland opening facing its original direction; ABB instructs technicians to record that orientation before removal. A misoriented gland can obstruct cable routing, and the motor cover must close without trapping internal cables. Stop assembly until the gland direction and cable clearance are correct.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which plug replaces the protection filter when 3HAC043456-003 is installed on a Foundry Plus robot?
Use the transparent plug or sight glass enclosed with the new spare and tighten it to 20 Nm ±10%. ABB applies this Foundry Plus step to the axis-4 motor before installation.
Why are paired removal tools specified when 3HAC043456-003 will not release from the gearbox?
Using the tools in opposite holes distributes the extraction force. ABB explicitly requires the removal tools to be used in pairs.
What is the stop signal if 3HAC043456-003 binds while separating from the gearbox?
Stop applying force because ABB warns that the gears can be damaged during motor-to-gearbox separation or mating. Re-establish straight, supported extraction before continuing.
How is the sealed interface checked after 3HAC043456-003 is secured?
Perform the leak-down test specified by ABB after the motor is fastened and before the repair is released. A visual cover check alone does not complete that procedure.
Can the self-threading motor-cover screws be reused with 3HAC043456-003?
No. ABB states that reusing those self-threading screws can damage the threads; fit standard replacement screws when closing the motor cover.
Where is temporary brake-release power connected during installation of 3HAC043456-003?
ABB specifies 24 V DC at connector R2.MP2, positive pin 2 and negative pin 5, while the pinion is mated. Disconnect that temporary supply after fastening.
