The main clutch bearing appears to be sealed. So nothing you can do with it. I can't tell if the secondary bearing is sealed or not. I apply a light oil on the gears and at the secondary bearing about once a month when I'm flying a lot. I have heard that one of the instructions sheets that come with the EME55 starters tell us to use a heavy grease on the gears. I don't recommend that because it will atteact and hold dirt and grit and make a mess. These gear don't get much use so should hold up well with the light oil.
