17. Place the lower azimuth pivot (item 3) over the foundation anchor bolts and
loosely install (Qty 6) 1.0 inch galvanized washers (item 24) and (Qty 6) 1-8
UNC fluorocarbon nuts (item 26).
18. Place a surface level on the top surface of the lower azimuth pivot pin and
adjust (3) equally spaced 1-8 UNC anchor nuts on the bottom side of the base
plate until the pivot is level. The other (3) bottom nuts should be lowered
slightly to avoid binding the base plate. Hold the bottom (3) nuts which are
in contact with the base plate fixed with a wrench and tighten (3) top nuts
against the base plate to 240 ft-lb (325 Nm).
19. Check the level to ensure the lower azimuth pivot pin is level.
20. Rotate the remaining (3) bottom nuts and (3) top nuts against the base plate.
Caution must be taken not to distort the leveled pin. Tighten all anchor nuts
to 240 to 275 ft-lb (325 to 372 Nm).
21. Install eye bolt (item 22) to upper azimuth pivot (item 2) as shown on sheet 3
of Drawing 519054. Attach a string to the eye bolt and suspend a plum bob
directly over the lower azimuth pivot as shown on sheet 5.
22. Attach upper azimuth pivot (item 2) to legs (item 4) with 1.0-inch hardware
(items 24, 25 and 27). Adjust the leg anchor bolts as require to install
hardware and secure a ground cable bracket (item 16) under one of the 1-8
UNC bolts. Tighten 1.0 inch hardware to 600 ft-lb (813 Nm).
23. Remove the crane from the mount.
24. Adjust the anchor bolt nuts securing the legs to the foundation as
required until the upper and lower pivot is plum (vertically aligned).
See sheet 5 of drawing 519054.
25. Attach wrench to the top and bottom 1-8 UNC foundation anchor
nuts and tighten to 240 to 275 ft-lb (325 to 372 Nm). Be sure to evenly
tighten the nuts so as not to distort the legs.
26. Loosen hose clamps as required and slide back the azimuth actuator
boot.
27. Extend the azimuth actuator screw by rotating the screw by the clevis
until the pin to pin jack length is greater than 64.0 inches (162.5 cm).
28. Remove the retainer rings and PVC spacers from the azimuth actuator
clevis pin.
29. Attach azimuth arm spacer and sector bars (items 6,7,8 and 9) to the
pivot pin and lower mount flange with 1-8 UNC galvanized hardware
as shown in sheets 6 and 7 of Drawing 519054.
30. Replace retainer rings to clevis pivot pin.
