E-4660 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:
- Gearbox reaction arm coming loose and causing major damage to the turbine as the gearbox spins on the shaft.
- Flex coupling failure
- Spring tube failure and wear
- Hub arm wear
