2.4.9 Reflector Mounting
NOTE
The assembly and alignment of reflector must be completed
per instructions in paragraph 2.4.6 of this manual before
installing antenna hub to mount.
1. Prior to lifting the reflector and hub, swing the elevation actuator over to
a horizontal position toward the legs as shown on sheet 8 of drawing
519054. Place a wood block between the elevation actuator assembly and
mount as required to prevent damage to actuator assembly.
2. Prior to lifting the reflector and hub, install 0.5 inch eye bolt (item 39) and
(Qty 2) support plates (item 19) to hub assembly with 0.5 inch washers
and nut as shown on sheet 8 of drawing 519054.
3. Attach three 30 foot nylon lifting straps using three shackles (part no.
521993) to antenna hub as shown in Figure 2-5 for lifting the reflector
assembly with a crane. Use short straps, as shown in Figure 2-5, to choke
lifting straps near the subreflector mount and spars to prevent side forces
on spars during lifting.
4. Lift the assembled reflector and position hub over mount as shown in
sheets 8 and 9 of Drawing 519054. Install (Qty 2) elevation pivot pins
(item 11), with the tapered end toward the center of mount
, through
bearing, spacers, and washers.
CAUTION
The pin (item 11) must be installed with the tapered end
toward the center of mount. Assembly problems will occur
with the elevation Limit Switch and Resolver package
installation if the tapered end is installed toward the outside.
