CHAPTER EIGHT
SECTION 8.1
BOOM TRUSS (continued)
PHILLYSTRAN TRUSS
At the top of the boom truss mast, install the 5/16” x 3” bolt and all the 5/16” and 3/8” washers to attach
the two 5/16” turnbuckles as shown in
Figure 8.10.
Install the 5/16” Nylock nut (PN 60-0046) at the end
of the the 5/16” x 3” bolt. Tighten the 5/16” nut so that the turnbuckles are snug against the washers
but still can move up and down.
Figure 8.11
shows the Phillystran layout with appropriate fasteners.
