30. Move telescope cylinder #2 (501) rearward, away from
tele 3 (401), to take up slack in the five extend cables (6)
and ensure they are not crossed (see Figure 4-80).
31. Apply multipurpose grease to top (as oriented) and sides
of telescope cylinder #1 (502) in the areas where the
wear pad of telescope cylinder #2 (501) will touch (see
Figure 4-80).
32. Simultaneously insert telescope cylinders #1 (502) and
#2 (501) into tele 3 (401). Ensure the ends of the two
retract cables (7) that are attached to the boom nose
pass through the pocket (D) in the wear pad (514) that is
attached to the front of telescope cylinder #2 (501) (see
Figure 4-81 and Figure 4-82).
Once the two cylinders have been inserted into tele 3
(401), gather the ends of the two retract cables (7) that
are attached to the pin (511) in telescope cylinder #2
(501) and hold them together above cylinder #2 (501)
using a C-clamp or similar (see Figure 4-83).
