INSTALLING THE OPTIONAL TRUSS (continued)
PHILLYSTRAN TRUSS INSTALLATION
The following explosion drawing for the Phillystran truss will come in handy while working through the
next section. Figure 10.10 shows the detail at the top of the truss support mast. Insert the 5/16” x 2-
3/4” hex head bolt (PN 60-0107) through the boom truss mast. Position each 4 inch turnbuckle (PN 60-
0083) over the bolt. Place two 5/16” flat washers against the outside turnbuckle. Attach the 5/16” Ny-
lock nuts (PN 60-0046). Figure 10.11 shows the Phillystran layout with appropriate fasteners.
