A wind turbine gearbox is one of the most expensive components to lose, so catching damage early and choosing the right fix matters. We match owners and asset managers to independent drivetrain specialists who inspect, repair and, where needed, exchange gearboxes.
Whether you need a borescope inspection and oil analysis, an uptower bearing swap or a full down-tower exchange, tell us your platform and symptoms and we match the right provider.

A failed gearbox is the classic unplanned outage: a crane, a replacement unit and a week of lost generation. Wind turbine gearbox repair exists to head that off, or to put the drivetrain back together quickly when the worst happens.
As the Australian fleet ages past mid-life, gearbox bearings and gears move into the window where failure rates climb. The difference between a cheap outcome and an expensive one is usually how early the damage is found and how well the repair-versus-replace call is made. Data from a condition monitoring programme often provides the first warning.
Every sensible repair starts with evidence. A borescope passed through the inspection ports shows the condition of the gear teeth and bearings across the planetary, intermediate and high-speed stages, while oil analysis and particle counting reveal wear metals, water and contamination that signal trouble before it is visible. Together they grade the damage and tell you whether an uptower repair will hold or whether the gearbox needs to come down.
Not every fault means a main crane. A great deal of work can be done uptower (in-situ), with the gearbox left in the nacelle: high-speed-shaft bearing replacement, intermediate-stage bearing work, seal and filter changes, and cooling repairs. An oil change and full system flush remove contaminated oil and wear debris, protecting the gears and bearings and extending service life. Uptower work keeps the turbine out of the crane queue and gets it back online fast.
When planetary-stage damage or widespread contamination is confirmed, the gearbox comes out. That is a main component exchange: the nacelle is opened, the gearbox lifted out and either workshop-repaired or swapped for a factory-rebuilt exchange unit. Lining up the crane, the exchange gearbox and the right parts and spares in one planned window is what keeps the cost and the downtime contained.
The repair-versus-replace decision is where good advice earns its keep. Localised high-speed or intermediate-stage faults caught early are strong repair candidates; planetary-stage failure and secondary damage across multiple stages usually point to a replacement or a rebuilt exchange unit. The independent specialists we match weigh the inspection and oil findings against the age of the turbine and the cost of a crane, then recommend the option that protects your return.
