This is why JFP specifically told you:

Take your time, read and follow the LN directions (I am not a fan of using setscrews to hold the shaft).

I wouldnt remove the bearing without removing the tensioners. Thats how I did mine and didnt have this problem. Also, if you have that much oil leaking past the bearing, it may not be in such good shape. When you get it out, I bet theres some play in it.
