2.
Remove the bolts and shims securing the telescope cyl-
inder rod trunnion blocks to boom section 1 and
remove the trunnion blocks. Using a hydraulic power
supply, extend the telescope cylinder out of boom sec-
tion 1.
3.
Remove the bolts and shims securing the telescope cyl-
inder barrel trunnion blocks to boom section 2 and
remove the trunnion blocks.
4.
Remove the bolts securing the adjustment mount and
disconnect the adjustment mount from boom section 1.
5.
Carefully pull the cylinder and ropes from the boom
assembly until there is access to the extend rope sup-
port. As the cylinder and ropes are removed from the
assembled boom, do not allow slack to accumulate in
the ropes between the rope support and the sheaves on
the cylinder assembly. The rope adjuster mount must
travel at twice the rate the cylinder is extracted to con-
trol slack.
