The paddle wheels, o-rings, and shafts were changed at the T2 cooling package for the following sensors:

• B1A:T2:FGCOLA
• T2CS:FGTGT
• T2CS:FGDEM
• T2CS:FGSEC
• T2:FGCOLB

No major issues were noted. Some residue was observed upon cleaning the sensors. No leaks observed when turning water isolation valves back on.

Two of the sensors, FGCOLA and FGTGT, experienced anomalies during the previous beam run which resulted in faults (#14656 and #14501, respectively). The system is not yet running in order to confirm whether the replacement has resolved the faults.

The schematic which contains these sensors is TBP0902.
