Dennis,
Actually it does cause the same problem in the Legacy. It is just more serious in the 320/360 and that is where my personal involvement has been greatest. While the write-up focused on the 320/360, I briefly walked through the Legacy pump changes. The pump design could have remained identical to the 320/360 models if the dump valve return line had been plumbed directly back to the reservoir. The higher volume flow rate is still a beneficial change as the Legacy has more fluid volume to move.
Given the amount of interest shown, I have started work on graphics for the Legacy hydraulic system so I can expand that section of the write-up.

Hi Chris,
You said,
"Here are the instructions to cure the problem for the 320/360s that
have the Legacy type pump installed. http://www.n91cz.com/Hydraulics/Pump-Unlock.pdf
-should take about 15 minutes on the bench."
I have what I think is the Legacy type pump in my Legacy. Just
curious why the Legacy type pump doesn't cause a problem in a Legacy but does in
a 320/360.
And a big thank you for all your effort on understanding and
documenting our hydraulic systems!
Best,
Dennis
