Pump Rebuilt
Equipment/Beam Line: 

Pump rebuilt and operational. 

Pump was originally installed on the Helios Turbo Cart.  Pump was leaking oil out of the shaft seal on to the drip tray.  Pump was also not performing well.  Pump was disassembled and metal parts were washed in Mineral Spirit and then in Methanol.  A major repair kit was applied.  Pump was tested and it was not performing well and when the ballast was turned on oil came pouring out of the ballast hole rapidly.  Subsequent disassembly revealed that the module gasket was installed flipped along the vertical edges.  With that reset the pump recovered and went down to 10mTorr on the CG at the bench.  Pump put aside for spare.
