As I’m going to sell my efoil, I decided to make a big service on everything, and the most challenging for me is the gearbox Neugart PLE 40. I had more and more noise coming from the propulsion unit so I first changed the motor, and now I work on the gearbox. I first asked the Neugart’s seller from my country (Switzerland) the price for a check service, they didn’t want to do it and wanted me to buy a new one. I then insisted and asked them to at least send me a few small components so I can do it by myself and they agreed. First challenge was to know how to open everything.
The first part which contains the coupler for the motor came out when I tried to separate the motor from the gearbox (here after cleaning).
It is for me one of the main problem with the Pacific Meister system, it’s very complicated to separate the motor from the gearbox after some time, the access to the screw via the small hole in the 3d printed piece is ok, but even after having removed it, and pulled back as strong as could, it was just impossible. So I had to cut the PLA piece to have a better access and worked with 2 screwdrivers to have leverage where I could to separate the motor from the gearbox.
Then you have to unscrew the screws on the side of the gearbox and everything goes out direction motor.
And how my god it looked quite bad
