CHAPTER EIGHT
SECTION 8.5
MAST PLATE AND DOUBLE TRUSS (continued)
PHILLYSTRAN TRUSS ASSEMBLY
Install the eyebolts on each side of the truss boom. The 3/8” x 2.5” eyebolts (PN 60-0151) come with a
standard nut and flat washer, you will need to remove these and use the provided 3/8” Nylock nut (PN 60-
0050) instead as shown in
figure 8.50
. Apply anti-seize to the bolt and tighten the Nylock nut firmly onto
the truss boom as shown in
figure 8.51
.
Each turnbuckle assembly consists of two 6 inch turnbuckles (PN 60-0070), one 3/8” x 1-3/4” stainless steel
hex head bolt (PN 60-0152), a 3/8” Nylock nut (PN 60-0050) and two 7/16” galvanized flat washers (PN 60-
0144). The flat washers are 7/16” so that they will completely cover the ends of the turnbuckles during the
tightening process. Be sure that each of the flat washers are on the outside of the appropriate eyebolt as
shown in
figure 8.53.
Figure 8.52
shows the proper sequence for attaching the turnbuckles to the eyebolt. Be sure to apply anti-
seize to the 3/8” bolt before tightening. Tighten snugly but loose enough for the turnbuckles to move.
Repeat for the other side of the truss mast.
Figure 8.53
shows the completed truss turnbuckle assembly.
