The hydraulic cylinder on the West side of the service bridge (used to raise the bridge for insertion into the Cyclotron) failed this morning, leaking oil in the vault tunnel.  Most likely this was due to a failed seal or gasket.

Maico Dalla Valle has removed both the East and West cylinders for refurbishment and is pursuing repair kits from Hyseco.

The purple coloured cylinder on the East side has been slowly leaking oil for some time.  A gasket in the West cylinder (yellow) seems to have failed and a broken piece of the gasket was removed during the disassembly, shown in the photo "Hydraulic Cylinder Gasket 4 Feb 2013 008.jpg" attached.

Cylinder model number is ENERPAC RC-254.
