help needed with 904

Just that last part about the pump. That's the last piece I put in I'm pretty sure and I haven't really cracked it open or got into that yet as I'm not sure about it. I guess I'm finding too much crap going wrong with the first things that I got to put in to start thinking about the last things that I put in LOL. I'm glad you're staying up with me though because one day I could do nothing and the next day it could be in the car LOL.
Remember the whole visual learning thing? I just figured it out it is because I haven't pulled it apart and seen it with my own eyes that I can visualize what you're talking about. I'll crack that open today And maybe review it with you later ?
First things first, I want to get this one two clutch pack drum and input shaft part completely together. Now as far as the input shaft and its drum- I don't have to take those two things apart do I? I tried and it didn't want to come apart and I didn't want to do anymore forcing. I'm not sure if there's a seal of any kind that needs to be replaced inside there anyways?


Which part?
