• Use 7/8 by 2-1/4 in (57 mm) hardware Note: Angles are attached edge out with flat of angle facing inward. 301786 Figure 16 Align panning frame/azimuth pivot assembly by swinging panning frame through its entire arc. Slightly snug panning frame/pivot assembly hardware, and again swing panning frame through its entire arc. Continue this procedure until mounting hardware is ready for tensioning. Note: Do not tighten hardware on 301786/201022 azimuth pivot assemblies at this time. 21 Installation Procedures Azimuth Jack Screw Assembly Step 1 Step 2 Refer to Figure 17. Apply RTV to flange surface and attach 200013-4/301841 azimuth jackscrew to 201021 azimuth pivot assembly as shown. • Use 1-1/4 by 3-1/2 in (89 mm) bolts, lock washers and nuts Note: Mounting hardware is included with corresponding jack assembly hardware kit. Figure 17 Attach 200131 azimuth jack extension to 200013-4 azimuth jack screw (manual, low- and medium-speed applications only) as shown. • Use 7/8 by 2-3/4 inch (70 mm) bolts, flat washers and nuts. Note: Type 301841 azimuth jack screw is used only for high-speed applications. 22 Installation Procedures Step 3 Step 4 Step 5 Refer to Figure 18. Raise the azimuth pivot/jack screw assembly, and attach to 200088A joint assembly. • Use 1 by 2-1/2 inch (63 mm) hardware. Note: Mounting position of azimuth/pivot jack screw assembly is dependent upon azimuth range requirements and corresponds with mounting position of 200035 outrigger assembly (if utilized). Figure 18 Refer to Figures 19A and 19B. After azimuth pivot/jack screw assembly has been attached to the joint assembly, attach remaining hardware as shown to 1/2” (13 mm) stud and apply supplied Loctite to all nuts. Position panning assembly to 0° azimuth and align 200022 pivot assembly with corresponding azimuth jack screw or 200131 azimuth jack extension. Remove band clamp from jack screw boot. Rotate jack screw to extend to pivot assembly. Attach jack screw to pivot assembly. • Use 7/8 by 2-3/4 in (70 mm) bolts and nuts (P/O jack assembly hardware kit.) 23 Installation Procedures Figure 19A Figure 19B Replace previously removed jack screw band clamp assembly. Note: Attach .jack extension to pivot assembly using 7/8 by 2-3/4 in (70 mm) bolts and nuts (P/O jack assembly hardware kit), for 200013-4 azimuth jack applications. For motorized mounts only, remove oil plug on motor assembly gearbox and replace with supplied vent plug packaged with the motor assembly. Note: Ensure hole in vent plug is positioned downward. Step 6 24 Installation Procedures Elevation Jackscrew Assembly Step 1 Refer to Figure 20. Apply supplied RTV to indicated flange surfaces and attach 2000133/ 200048 elevation jack screw to 200128 elevation extension assembly as shown. • Use 1-1/4 by 3-1/2 in (89 mm) bolts, washers and nuts Note: Mounting hardware is included with corresponding jack assembly hardware kit. APPLY RTV APPLY RTV APPLY RTV 3/4 x 3” LG. (75 mm) Figure 20 Attach 200022 pivot assembly to enclosure tripod leg assembly Note: This may also be performed during reflector assembly. Step 2 • Use 3/4 by 3.0 in (75 mm) bolts, lockwashers and nuts. 25 Installation Procedures Step 3 Refer to Figure 21. Apply supplied RTV to flange surface and attach remaining end of 200128 elevation extension assembly to corresponding 201022 pivot assembly as shown. • Use 7/8 by 2-1/4 in (57 mm) hardware. For motorized mounts only, remove oil plug on motor assembly gearbox and replace with supplied vent plug packaged with the motor assembly only after elevation jack is in final operating position. Note: Ensure hole in vent plug is positioned downward. Figure 21 26 Installation Procedures Grounding CableAttachment Step 1 Note: Thoroughly clean exposed portions of grounding cables, unplated portion of universal terminals and corresponding mounting surfaces using a wire brush. Liberally apply supplied 203233-2 conductive grease to all connection surfaces prior to and after installation. Thoroughly remove conductive grease from hands and tools using soap and water. Refer to Figure 22. Remove existing 7/8 by 2-1/4 in (57 mm) hardware at indicated positions and install grounding cables as shown. • Use supplied 7/8 by 2-3/4 in (70 mm) hardware Figure 22 27 Installation Procedures Step 2 Step 3 Refer to Figure 23. Remove existing 7/8 by 2-1/4 in (57 mm) hardware from both elevation pivot/joint assemblies at indicated positions and install grounding cables as shown. • Use supplied 7/8 by 2-3/4 in (70 mm) bolts and nuts Note: Supplied 3/4 in hardware is installed after reflector to ground mount installation. Figure 23 Securely tighten all remaining ground mount/jack assembly hardware per hardware tensioning procedure. The tripod ground mount assembly is now completed with the necessary operational essentials. All ground mount options have separate instructional bulletins located in the parts kit that contain the option. The next step in the installation process is the reflector assembly. Proceed...
