Replacement & Compatibility FAQ
Q: Can 3HAC034863-005 replace 3HAC027186-001?
A: No — they are different axes. 3HAC027186-001 is axis 1; 3HAC034863-005 is axis 2. Both may need replacement simultaneously after high-cycle operation.
Q: Is a refurbished gearbox safe for production use?
A: Yes, when rebuilt to OEM spec with new bearings and seals. Our refurbished units carry a 6-month performance warranty.
Q: Do I need to re-calibrate after gearbox replacement?
A: Yes. ABB recommends a full axis calibration (CalPendulum II or Levelmeter) after any gearbox swap. We can supply the calibration pendulum on loan.
Q: What is the lead time for a new OEM unit?
A: New OEM units typically ship within 3–7 business days. Refurbished units ship within 1–3 business days. Contact us for urgent requirements.
Q: Do you ship internationally?
A: Yes — we ship worldwide with DHL Express, FedEx, and sea freight options. Export documentation included.
