INSTALLING THE RADIO/TRIA ASSEMBLY ON THE TUBE SUPPORT ARM
Be sure to orient the radio and tube support arm correctly. The
radio is attached to the bottom of the tube support arm. When
you are done, the assembly will look like the illustration at the
bottom of the page. You will put the radio cover on first.
1. Place the radio cover top over the top of the radio. The radio
cover top has two holes that align with the bolt holes at the
top of the radio. See the illustration at right.
2. Place the radio cover bottom over the bottom of the radio.
Align the bottom and top cover screw holes.
3. Use a #2 Phillips-head screwdriver to tighten the four prein-
stalled screws.
4. Place the O-ring in the circular depression in the square end
of the feed support tube. See the illustration at right.
5. The square end of the tube support arm should be aligned
with the square end of the radio/tria assembly so that you
can install four screws with lockwashers. Install the lock-
washers on the screws. Then use the Allen wrench to install
the M4 Allen screws, but do not fully tighten them.
6. Align the bolt holes on the top of the radio with the bolt
holes on the bottom of the tube support arm.
7. Install the 5/16-18 bolts in the aligned holes. Finger tighten
them, but do not tighten them farther than that.
8. Use the Allen wrench to tighten the Allen screws that are
holding the tria and feed horn.
9. Use a 5/16-inch socket wrench or open-end wrench to
tighten the bolts attaching the radio to the tube support arm.
