WBSC9 ETMx SEI HEPI Actuators--All connected

We got all the Actuators connected.  The last one, V3, took a while as we swapped out the suspect parker valve noted by Jim earlier.  The first one we swapped in L170 also appeared to do the same pull down Jim noted.  But this may have been a ringer.  We had not bled the actuator yet as we wanted to compare the performance and then we learned this valve had been removed from WHAM6.  However, we thought we were in trouble as the swap at WHAM6 was possibly unneeded because the problem there was that the Supply & Return hose were miss plumbed.  Still, we pulled L170 and swapped in L206 and bled the Actuator for 1.5+hours.  After we put the Actuator back in run mode, the Actuator drove back to a near center position so we deemed the valve problem addressed and attached this final Actuator.  Dial Indicators suggested we had tilted the table a few tenths, C2/4, so we followed with some tweeks of the big HEPI Springs to bring that back to start position.  Have alerted IAS/Jason that we are ready for a post Actuator look--he may be looking now.
