. Insert four of the 5/16” x 4” hex head bolts (PN 60-0066) so the threads of the
bolts are on the boom side of the mast plate as shown in
figure 8.02
. Insert the 1/4” aluminum spac-
ers (PN 10-1613-11) onto the hex head bolts, followed by the first half of the 1-3/4” aluminum saddle
(PN 10-1601-01) as shown in
figure 8.03
. Position the truss mast (PN 10-1614-41) so that it is resting
on the aluminum saddle, then slide the other half of the saddle onto the hex head bolts. Thread on the
5/16” Nylock nuts (PN 60-0046) for the left side of the saddles (when facing the boom), as shown in
figure 8.04
. The hex head bolts on the right side of the saddles (circled in yellow) are used to install
the connector junction box. .
Install the connector junction box on the saddles so that the lid of the junction box opens from the bot-
tom as shown in
figure 8.05
. Note that there are more details on the connector junction box installa-
tion in
Chapter Nine
. Holding the connector junction box in place, insert the 5/16” Nylock nuts onto the
hex head bolts. Turn the truss mast until the upper hole is perpendicular to the boom. Now tighten
the 5/16” nuts fully.
