6. Final orientation of case. Verify that the trunion mounting post is in the far corner,
opposite from look direction as shown in Figure 8. Adjust case orientation as required.
7. Remove the trunion assembly from its corner pocket in the lower half of the case.
Place the trunion assembly over the trunion post which protrudes from the lower case. See Figure
9. Ensure that the trunion seats fully and swivels easily in azimuth. Lightly tighten the six thumb
screws. Ensure that the trunion does not wobble yet turns freely on the post. The thumbscrews
will be tightened slightly more when proper azimuth has been established.
8. Adopt a firm stance and grasp the lower dish segment/support arm. Pull the lower
dish/support arm from the case, pulling straight up and exercising caution not to tear the case foam
or damage peripheral dish hardware (latches and dowel studs). Notice that there is a large 5/8"
bolt running through the dish support arm near the merger of the two box-beam segments which
make up the support arm. Guide the lower dish assembly so that this bolt slips in to the slotted
trunion forks. The antenna support arm fits snugly in between the trunion forks. Guide the 5/8"
bolt into the receiving slot in each of the two trunion forks. Spread the 5/8" flat washers such that
they are on either side of the trunion forks. Refer to Figure 10 for detail. Hand tighten the 5/8" wing
nut.
9. Install the elevation adjust mechanism. Remove the elevation adjust mechanism
from the case and pull away the hitch pin and associated flat washer from the lower bolt.
(Refer to Figure 4.) Thread this bolt into the nut which is welded to the receiving bracket on
the back end of the trunion assembly as shown in Figure 11. Note that this nut/bolt
combination is left handed and must be engaged by turning counter clockwise. Thread this
bolt into the nut by 1/2" or more.
Warning: Never allow the lower end of the elevation adjust mechanism to
inadvertently become unthreaded during elevation adjustment. Unthreading
of the elevation adjustment mechanism would result in the dish suddenly
dropping in elevation, which could damage the radio/LNB.
Remove the 1/2" wing nut and flat washer from the upper elevation receiving bracket on
the upper box-beam segment of the antenna support arm. (Figure 11) Tilt the dish back so
that the eyelet on the elevation adjust arm slips over the 1/2" bolt. Replace the wing nut and
washer, finger tight.
