Some water got in and has been centrifuged from the rear all the way to the front damaging the front bearing:

Therefore we made some extra parts that will make the backside more weatherproof. The white ring is glued on the backside of the generator, and the blue cap is glued on the axle. When installed, the white ring will be over the blue cap, ensuring no rain get's in along the backside.

We also replaced the previous bearings (that were completely open) by sealed ones of half the price!
