Hi Dave, <br>
Yes I think so even if we only go 1/3 to 1/2 the way back I can get
to this area. We may need to go back further however if I need a
manlift to check the entire detector.<br>

<pre wrap="">Nice going guys!
Thanks for the update.
Could partial retraction of the FC be less work and still allow repair?

<pre wrap=""> Calvin and I went into the Hall to investigate the leak in Sec5 CC
today. Using a bore scope and one of our refrigerant leak detectors I
was able to find what may be our problem or at least part of it. I was
able to raise panel 2 TOF's enough to see the bottom window which
allowed me to leak test part of the vertical edge, side and back. I got
strong readings at the piping in the lower corner and detected nothing
above or around that area. From what I can tell one of several things
may be causing this, movement may have loosened a coupling, caused a
stress crack in the piping or pressure from cables and piping may have
rubbed a hole in the window. The plus side to this is that I am
confident that I can repair at least this problem without having to
remove the detector. This may not be the only problem but I am fairly
certain it is a major contributor. I can get a much better idea of what
else may be a problem when the forward carriage is retracted.
Thanks
Denny
