Dear Founds, I’m still a fresh smart fan, so I still don’t have the structure and function of each component on the screen. I need your expert advice. For a few weeks I’ve always had an oil drop under the gearbox after rides. At first I thought it was a leak on the gearbox, but after a motor oil change, with change of the oil pan, I see that the draining oil is unconsumed. If the ball is not moved, then drips si e also not. Which motor oil bearing components are the above the arrow, which are not visible without engine lowering? I have colored the oily areas yellow. (The lower picture is not the original, just a view of the lower gear side). Would I be pleased about a feedback. Gruss. Wigand
