The four water connections on the front end plate of the APTW that will connect to the HTV were tested for replacement with the manipulators:

• The pin on these connectors were fairly easy to remove and replace with the old pin detent tool.
• The pin detent tool could also be used to manipulate the water lines while protecting the sealing face.
• The horizontal VCR joint on the DRIVE BEAM CONE (ATA3674) could be undone with the manipulator and standard wrenches, it is advisable to use 'semi-closed' wrenches on the nut to prevent it from dropping when torquing or undoing the joint.
• Of the four water lines, only the top line could be taken out and returned by hand, testing with manipulator still to be done.
  • It would be nice for this top most line to have a clamp or something to keep the VCR nut on the bottom U-bend from falling.
• The second line from the top interferes with the bus bar when trying to be removed by hand.
• The second line from the bottom has a VCR connection obstructed by the same bus bar when trying to remove by hand.
• The bottom line catches on the other lines when trying to remove by hand, the other lines likely need to be removed first to allow this line to be exchanged.
• is the intent for the bus bar need to be removed to exchange these lines?
• The VCR nuts on the water lines located by the bottom of the bus bars will require the turntable to be raised most of the way up to access with the manipulators.

 Testing will resume in the following week for these water lines.
