I opened my pool today and my VGreen 165 is making a noise like a bearing is going bad. I tried searching what size bearings it takes but it doesn't seem like that info is posted anywhere. Inyo actually has a video stating only certified professionals should disassemble a VS pump. I am going to attempt replacing the bearings myself before dropping a few $100 on another motor. Does anyone know what size bearings the VGreen 165 takes?
