7.10.2 Front Panel/Door Assembly Replacement
This procedure assumes that the Front Panel/Door Assembly was removed in Section
7.10.1. The four pan-head screws that held the large and small links were originally
installed with Loctite 242 thread locking adhesive. These screws should again be
locked in place when replacing the Front Panel/Door Assembly. There are three ac-
ceptable choices in order of preference:
• Place a small drop of Loctite 242 on four new pan-head screws supplied
with the replacement assembly. The screws are 4-
40 x 3/16” Pan Heads.
•
Place a small drop of Loctite 242 on the four original pan-head screws that
were just removed.
•
Use the original pan-head screws as is. The Loctite residue is better than
nothing.
1. While supporting the Front Panel/Door assembly with one hand, slide the large
link over the threaded standoff and using a No. 1 Phillips screwdriver, install a
4-
40 x 3/16” pan -head screw with Loctite. See Figure 7-18. Repeat for the other
side.
2. Slide the small link over its threaded standoff and using a No. 1 Phillips screw-
driver, install a 4-
40 x 3/16” pan -head screws with Loctite. See Figure 7-18. Re-
peat for the other side.
3. Slide one of the rack mounting brackets along the side of the Library and align
the three threaded holes in the bracket with the screw holes in the side of the li-
brary’s chassis. Using a No. 2 Phillips screwdriver, install the three flat-head
screws that were removed earlier. See Figure 7-17. Repeat for the other side.
4. Reinstall the Carriage Assembly into the RLS as described in Section 7.
