Wind Gearbox Repairs – Product

We provide both standard gearbox upgrades as well as customized upgrades. Our R&D department uses the latest and most up-to-date design software for gears & bearings thus enabling the design engineers to carry out extensive calculations on all gearbox components. Our decades of gearbox know-how make us able to design customized gearbox upgrades and critically analyse gearbox failures.


The typical workflow for a wind turbine gearbox repair comprises the following steps:

  • Complete disassembly and cleaning of all parts
  • Failure detection, analysis and troubleshooting
  • Solution design in cooperation with the customer
  • Supply of new parts
  • Reassembly
  • Spin testing
  • Full documentation


After the completion of the gearbox repair/refurbishment, a service report on the reconditioned gearbox is issued by the service department and supplied to the customer.

Repair and reconditioning or replacement of the bearing/bearings on main shafts as well can be handled by the service department.
