1) Remove the four (5) cap screw assemblies in
the corners (Figure 305) consisting of the
following:
a. M6x50 socket head cap screws {Code

2) Insert a screwdriver in the casing above
the stirrup adapter as shown in Figure 306.
Carefully pry the casing open.
3) When the cover opens enough, insert a
second screwdriver. Begin to lift evenly at the
corners of the cover as shown in Figure 307.
4) Inspect inside of cover {Code #63695, Pos.
2} for damage or evidence of wire rope jams
(Figure 308) and cracking near the stirrup bar
pocket (Figure 309).
All surfaces should be smooth to prevent cutting
or snagging of the wire rope. Replace the cover
if it is cracked or distorted.
