After hard closing GV20, we removed the old main volume turbo and installed the new shiny turbo at EX. We were able to leak check the GV joint with a background of 4x10^-9 Torr-L/s of helium, with no detectable leak, but ran out of time to leak check the main volume to find the air leak.

Next maintenance period we will soft close GV20 and let the {wet} turbo pump for enough time to reach a pressure comparable to main volume in order to valve it in and leak check suspect joints, and allow leak detector background to fall below 1x10^-9 Torr-L/s.

We also need to finish properly anchoring the turbo stand. Ran into a galled bolt at top plate, and a few anchor bolts are mismatched enough with pre-drilled anchor inserts that we need to file down the anchor brackets.

Good work, team.
