A ram air turbine includes a turbine with one or more blades, a strut removably coupled to the turbine and having a gearbox section and a drive section, a cover located at an end of the gearbox section of the strut with a test plug having a static seal, a turbine shaft and a bevel gear located in the gearbox section of the strut and a driveshaft and a pinion gear located in the drive section of the strut, wherein the pinion gear engages with the bevel gear. The turbine shaft may include a dynamic seal that provides sealing between the turbine shaft and the cover. The test plug may be a threaded plug. The cover may also utilize a dynamic seal. The turbine shaft may include a splined internal cavity for use with a ground test motor.
