1) So I just completed servicing the top part of my new to me Maxwell Freedom 800 on my 2003 Carver 366. Sadly it had been neglected & the pressure arm had been completely eroded away with just the stub of it left. I got a small kit that had a new pressure arm plus the little wire clip, but on mine, it looks like where the short end of the clip fits into a fitting on the case, that fitting has also been worn away. In the instructions in the manual, it notes: " insert a new insulator tube and pressure arm clip".
So I have the new clip, but nowhere do I see anything that corresponds to where an " insulator tube" would fit, nor do I see it included in the Maxwell service kit.
I have the photos & enlarged them but they don't show where this would fit.
Anyone know anything about where, how this is done?

2) I also want to service the bottom part ( gearbox ) because I can see some oil on the outside bottom of the shaft. From what I see in the manual, that it's fairly simple, to disassemble, And that you re-assemble it and then insert the "key" but I can't see what holds the key in place. I'd like to understand this before I take it to pieces.

Any help appreciated.
