Various PFCS "Pump Flow Control Subassembly"  Nicknames  :)

I was bummed they didn't color in the text for "MOTLEY" in actual motley.
Shouldn't reality posts be in "Advanced concepts"?  --Nomadd

The one on that was on P6 was called Leaky and the one on ESP-1 is Frosty.

Motley is the new one that just went up in the CRS-14 trunk.  And Trippy was the one that was just deorbited when Dragon left the station.

I'm still unclear about Trippy and Leaky. I assume Leaky is S/N 0004, the one that was swapped out in the 2013 EVA and was originally on the P6 2B channel, but has been sitting in one of the two EATCS slots since 2013 for storage.
Which P6 channel was Trippy - was it the 4B PFCS, or the 'new' 2B PFCS that was swapped in in 2013?
Or do I have it all wrong?
There are a total of 12 PFCS launched to date including the late lamented Trippy

Also, is Leaky already on the EOTP somehow, or is that robotics work still to be done prior to EVA?

It was installed in the night from 9th to 10th May.

Last night, Robotics Ground Controllers maneuvered the Space Station Remote Manipulator System (SSRMS) and the Special Purpose Dexterous Manipulator (SPDM) in position to extract the failed Pump Flow Control Assembly (PFCS) also known as ‘Leaky’.  They extracted the PFCS and stowed it on the Enhanced ORU Temporary Platform (EOTP) side 3.

I would suppose, that the PFCS, which was going down in SpX-14, was the one, that was changed out in 2013, because it was unserviceable. It makes no sense, to send one down which is still serviceable.
On the other hand I suppose, that Leaky is the spare which was used in the EETCS and was then as a spare on P6. It will now changed for what or ever reason with the spare on ESP-1.
The other two PFCS on P6 are in use on Channel 4B and on 2B(from the former EETCS, which was changed in in 2013), so actually no reason for changing.
But those are just my assumptions, no source.

ISS Daily Summary Report – 5/10/2018

Extravehicular Activity (EVA) Preparations: In preparation for next week’s US EVA 50 Pump and Flow Control Subassembly (PFCS) Relocate, the crew used computer-aided simulations to review EVA procedures via Dynamic Onboard Ubiquitous Graphics (DOUG) and the Robotics Onboard Trainer (ROBoT).  They also used Virtual Reality to review procedures associated with the Simplified Aid for EVA Rescue (SAFER).  In addition to this training, the crew completed a checkout of the SAFER units, continued with Extravehicular Mobility Unit (EMU) Long Life Battery (LLB) charging operations, and configured various cameras used during EVA

Robotic Operations:  Last night, Robotics Ground Controllers maneuvered the Space Station Remote Manipulator System (SSRMS) and the Special Purpose Dexterous Manipulator (SPDM) in position to extract the failed Pump Flow Control Assembly (PFCS) also known as ‘Leaky’.  They extracted the PFCS and stowed it on the Enhanced ORU Temporary Platform (EOTP) side 3.  After initial release, the SSRMS rebounded in the X and Y directions and contacted structure; survey of the P6 interface did not indicate any damage.  The Mobile Transporter (MT) was translated from Worksite 8 to Worksite 6 to complete last night’s operations.

It is going to be a busy night tonight outside the ISS.  Ground controllers in Houston will continue to configure the MSS for the PFCS EVA. The SPDM, will install PFCS ‘Leaky’ on the EOTP, after which the SSRMS will be moved to the EVA starting position. Later in the evening Ground controllers in Tsukuba, Japan will maneuver Japanese Experiment Module Remote Manipulator System (JEMRMS) from the Stowed Position to the Small Satellite Deploy Position in preparation for Japanese Small Satellite Orbital Demonstration (JSSOD)-8 satellite deploys tomorrow morning.

I have to correct myself. In the briefing it would mentioned, that Leaky is the one, which was swapped out in 2013.
So forget my assumptions.

I did some digging through the station reports and found a mention of some electrical troubleshooting on the outboard spare PFCS on the P6 Long Spacer in August 2017.

https://blogs.nasa.gov/stationreport/2017/08/02/

EVA-21 planning graphics indicate that the inboard spare PFCS was used to replace Leaky, so Trippy appears to be (er... have been) the other spare PFCS that was initially part of the EETCS.

ISS Daily Summary Report – 5/11/2018

Extravehicular Activity (EVA) Preparations: In preparation for next week’s US EVA 50 Pump and Flow Control Subassembly (PFCS) Relocate, the crew utilized Dynamic Onboard Ubiquitous Graphics (DOUG) Software to review crew translation paths and Space Station Remote Manipulator System (SSRMS) movement during the EVA. Once complete with this simulation, the crew continued reviewing the EVA Systems Briefing Package before conducting a second EVA Procedures Conference with ground specialists.  A checkout of the Rechargeable EVA Battery Assembly (REBA), used to power the glove heaters on the Extravehicular Mobility Units (EMUs), concluded the list of today’s EVA prep activities

Mobile Servicing System (MSS) Operations: Last night, the Robotics Ground Control team powered up the MSS and maneuvered the Space Station Remote Manipulator System (SSRMS) to stow the Special Purpose Dexterous Manipulator (SPDM), with the “Leaky” Pump/Flow Control Subassembly (PFCS), on the LAB Power Data Grapple Fixture (PDGF).  The SSRMS then released the SPDM and maneuvered to the start position in support for the EVA scheduled next week. MSS performance was nominal.
