Section 1: MECHANICAL INSTALLATION
1.6 Install Gyro
1) If using Plexus MA590 adhesive, the gyro should be installed when PC ‐ 120 is confirmed dry.
Apply adhesive to the hull structure (See Figure 11) in a manner that all gaps between the
saddles and the hull structure will be filled with adhesive when the gyro is lowered into position.
Excess adhesive will be needed to insure a COMPLETE BOND – some adhesive will get squeezed
out and must be cleaned off and discarded. If using the Plexus MA590 Adhesive Installation Kit
from Seakeeper, it is recommended to apply 2 full cartridges to the top of each hull stringer.
Work deliberate and fast as it takes some time to apply the adhesive to the structure. MA590
has a 90 minute working time at room temperature (23°C / 73°F). This working time can reduce
to 40 ‐ 50 minutes at elevated temperatures.
2) Once the adhesive has been applied, lower gyro onto hull structure.
3) Visually inspect the entire perimeter of each saddle to confirm that adhesive has filled all the
gaps on the saddle sides. If adhesive has
been applied correctly, it will squeeze
out around the sides of the saddles as
shown in Figure 12. If adhesive has filled
all the gaps, go to step 6. If using the
Plexus MA590 adhesive from Seakeeper
and the adhesive does not appear in
certain areas, inject using the provided
nozzle as shown in Figure 13. (Note
adhesive shown in picture is for
illustrative purposes only. MA590 color will be gray.)
