Kyle R., Gerardo M., Mark D. (Apollo), Tyler G. (Apollo) Spun-up and valved-in Diagonal Turbo pump (NOTE: Valve only partially opened as actuator mechanism is galling and will stick permanently soon). Isolated and vented IP7 with room air. Removed IP7 from isolation gate valve. Installed zero-length reducer with 1.5" pump port valve and evacuated volume between closed gate and zero-length reducer. Installed blank flange on IP7. Leaving the Turbo valved-in overnight and will only close following the removal of IP8 tomorrow so as to minimize valve cycling -> hopefully valve will close one more time before failing completely. 2500 L/sec large ion pumps (IPx) are being removed as opportunities arise so as to be refurbished.
