Locate the 7/16” X 5” threaded bolt (PN 60-0142). LIBERALLY apply anti-seize to this bolt as shown in
figure 7.02
. Note there is lubricant applied to four sections of the bolt. If you do not do this, the bolt
will likely gall. For information on galling, see the
Preamble
section of this manual.
To be sure your mast plate is oriented properly, refer to
figure 7.03.
When looking at the boom
(meaning that you can visually SEE the boom with the mast plate behind it) as it is mounted on the
mast plate, these 4 holes should be on the upper right side.
Insert the 7/16” x 5” threaded bolt through the two identical mast plates (PN 10-1610-22) as shown in
figure 7.04
. Secure with the 7/16” standard nut (PN 60-0161) and 7/16” lock washer (PN 60-0160) as
shown in
figure 7.05
. Tighten firmly.
Thread the second 7/16” standard nut onto the bolt until there is approximately 3/4” of clearance be-
tween the two standard nuts as shown in
figure 7.06
.
