CHAPTER EIGHT
SECTION 8.0
MAST PLATE AND DOUBLE TRUSS (continued)
MOUNTING THE MAST PLATE TO THE BOOM (continued)
Locate the 7/16” x 5” threaded bolt (PN 60-0142). LIBERALLY apply anti-seize to this bolt as shown in
figure 8.02
. 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 8.03.
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 left side.
Insert the 7/16” x 5” threaded bolt through the two identical mast plates (PN 10-1610-23) as shown in
figure 8.04
. Secure with the 7/16” standard nut (PN 60-0161) and 7/16” lock washer (PN 60-0160) as
shown in
figure 8.05
. Tighten firmly.
Thread the second 7/16” standard nut onto the bolt until there is
approximately 3/4” of clearance between the two standard nuts as shown in
figure 8.06
.
Slide the 5/16” x 5” hex head bolts (PN 60-0141) into the mast plate, and place the first half of the 3 inch
aluminum saddles (PN 10-1601-61) onto the bolts as shown in
figure 8.07
.
Place two 7/16” galvanized
washers (PN 60-0034) onto the EZ-Eye threaded bolt as shown in
figure 8.08
, BEFORE inserting the
threaded bolt into the EZ-Eye.
Position the mast plate to the boom, sliding the 5” threaded bolt through
the eyebolt as shown in
figure 8.09
.
