E-4660 Turbine Repairs and Upgrades

E-4660 Wind Turbine - Repairs and Upgrades

The E-4660 was Endurance’s improvement on the E-3120. It featured a large rotor diameter and bigger generator for a significant improvement in output.

The bedplate and shaft on the E-4660 are a major improvement on the E-3120 and to date, there have been no issues with these items.

The issues that are common on the E-4660 are as follows:

  1. Gearbox reaction arm coming loose and causing major damage to the turbine as the gearbox spins on the shaft.
  2. Flex coupling failure
  3. Spring tube failure and wear
  4. Hub arm wear

DC21 has many years experience in the repair of issues affecting the Endurance E-4660 turbines.
