There is a seal there to keep oil from leaking to the primary. Not sure what your seeing? Post a pic
This is the left side. Between the black lines. A small weep will develop a few drops at the bottom of the case where the rotor sits. If you can zoom in on the pic, you'll see that between the outer race housing and the ( seems to be separate ) piece between the bearing race and the thin steel that's between the race housing and the case. the gold looking line is where the leak is. if you can zoom you'll see that all is dry in all area's except that area. All other area's are dry. Can that be pressed out and fixed ? 20150817_180600.jpg
