300 Hour Generator Maintenance

Over time, the integrity of the generator's cylinder, piston, and seals will degrade and when this occurs a lack of compression may occur. As a result, the Löweheiser EFI generator has a recommended replacement lifetime of three-hundred hours. This is to ensure that both the generator and aircraft function and operate at their optimal performance. Similarly, Intelligent Energy fuel cells are subject to a degradation in performance over many hours, and thus, replacement is required after three-hundred hours.

Generator Removal and Installation

To remove a Löweheiser EFI generator, first remove the large clear and large yellow fuel lines from the fuel inlet and fuel return, unplug the telemetry cable which is inserted into the flight control box, and remove the four M3x8 socket screws located on each rail clamp. Be sure to support the generator while removing these screws, otherwise the generator may fall during removal. Use the same process detailed here, but in reverse order for replacement generators. Refer to Appendix A for torque specifications.

Fuel Cell Removal and Installation

To remove an Intelligent Energy fuel cell, first make sure to remove any gas lines that may still be connected to a hydrogen tank, unplug the telemetry cable which is inserted into the flight control box, and remove the four M3x8 socket screws located on each rail clamp. Be sure to support the generator while removing these screws, otherwise the generator may fall during removal. Use the same process detailed here, but in reverse order for replacement generators. Refer to Appendix A for torque specifications.
