All my fluids replaced, and I got a few hours in the seat today. Yay!
Replacing the hydraulic tube filter on the suction intake was making me sweat though. I had read here TBN to be careful not to cross-thread the aluminum tube into the steel case. I really had a dickens of a time getting the O-rings, banjo housing, and filter lined up. Only about two threads in I could feel a great resistance. Since the service manual says to apply sealant when installing, I thought there might be old sealant in the case threads jamming things up. I tried cleaning them with a toothbrush soaked in diesel. Still fought me all the way in, but the wrench was turning smooth with a steady torque that felt like 15-20 pounds until the O-rings were squashed and banjo tight against the case. Never thought it would take that much force.
I used paste with PTFE. Hope that is the right choice.
