(Mark, Tyler, Peter, Gerardo)
The old OFI was extracted out of HAM5 using the HAM installation arm. Once out of the HAM a lift was used to lower it onto a table for temporary storage.
The new OFI was installed using the lift to position it on the HAM installation arm, then set into the HAM on top of the height adaptor. The height adaptor was not removed to maintain the aligned position. The OFI was fasten to the height adaptor and all fixing bolts were torqued, also 2 vibration absorbers were moved from the old OFI to the new one. The OFI is "locked" in place using the transport shims, and tomorrow with the new earthquake stops it will be "released" giving us an opportunity to visit its suspended alignment.
Attached is a photo of the new OFI as it was being installed, yup! There is not much room, the arm was 1/2 inch away from black glass baffles on one end, and the other end very close to the ceiling of the chamber, to move the arm out we resorted to the removal of a yoke arm and it worked like a charm!
