1.0 Introduction This document is intended to give details and guidance to a boat builder or equipment installer to install the Seakeeper, Inc. Model 5500 Stabilizing Gyro. The gyro is capable of producing loads up to 14.7 kN (3300 lbs.) on each foundation saddle and careful consideration should be given to foundation design to insure it is capable of transferring these loads into the hull. It is assumed that personnel involved in installation are familiar with GRP structures as well as the use of high strength adhesives that will be ...

Product: Document #: Rev: Page: INSTALLATION MANUAL MODEL 5500 GYRO 90214 2 2 of 15 Section 1: MECHANICAL INSTALLATION 1.1 Precautions Gyro flywheel is supported by precision bearings. Make certain while unpacking and lifting gyro assembly to NOT drop or impart mechanical shock as damage to bearings could result. While handling / installing gyro assembly, protect exposed hydraulic brake cylinder rods (See Figure 1) from scratches or damage as this could lead to premature seal failure and oil leaks. While handling / installing gyro assembly, do not allow electrical fittings that exit bottom of gyro enclosure to come in contact with any surface or object as this could damage the fittings and potentially affect the vacuum integrity of the enclosure. ...

Product: Document #: Rev: Page: INSTALLATION MANUAL MODEL 5500 GYRO 90214 2 4 of 15 Section 1: MECHANICAL INSTALLATION FIGURE 3 – TRANSVERSE BEAMS CLEARANCE CONSIDERATIONS Refer to Figure 3 for recommended clearances to transverse beams. If a transverse beam is located under the forward brace, it must be 3” (76 mm) from the edge of the saddle beams to provide the necessary clearance for the swing of the motor power cable during gyro precession. Clearances aft of the gyro are shown to provide access for maintenance. ...

Noise/Soundproofing/Ventilation Gyro noise has been measured under steady state conditions (no wave load) in Seakeeper's lab and in our 43 ft test boat. The steady state noise is typically in the range of 70‐75 dB unweighted. As the frequencies emitting the highest sound pressures are low (like other marine machinery), it is recommended that the gyro be installed in a cage in a machinery space that is already treated with ...

90214 2 7 of 15 Section 1: MECHANICAL INSTALLATION 1.4 Preparation of Hull Structure Refer to Seakeeper Drawing No. 90219, Model 5500 Gyro Installation Details. Important dimensional and load information is given in this drawing that will impact the design details of the structure that will receive the gyro as well as selection of adhesive to bond the gyro into the hull. The foundation “saddles” of the gyro are designed to be bonded directly to the composite hull structure of the vessel to effectively distribute gyroscopic loads. Note that any paint or gel‐coat present in bond area should be removed so that adhesive will bond directly to laminate fibers and resin. A complete bond is required between the inside surface of the saddles and the hull structure. To aid in determining the quantity of adhesive required, the surface area of Port saddle bond area is 340 in ...

Use new paper towels for cleaning, not shop rags. ...
Page 17
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. ...

INSTRUCTIONS Product: All Document #: 90213 Process: Plexus PC‐ 120 Application Instructions Rev.: 1 Process Description: Instructions for use of surface conditioner Page 1 of 4 What is Plexus PC‐120? Plexus PC‐120 is a dual function primer/conditioner designed to clean surface contamination and leave a thin coating of primer on specific metal surfaces. Although designed specifically for cleaning and priming of Aluminum and Stainless Steel, PC‐120 can be used to clean other surfaces in special situations. Contact Plexus Technical Service for recommendations on any surface other than Aluminum or Stainless Steel. Plexus PC‐120 works by: Cleaning the surface of contamination using Isopropyl Alcohol to “lift” machine oils and other contamination. Depositing a thin Phosphate based coating to retard corrosion. Leaving a light “pink” color to assist in determining what areas have, and have not, been treated with PC‐120. How should PC‐120 be used? PC‐120 can be brushed, wiped or sprayed onto the surface being primed. ...
Page 22
INSTRUCTIONS Page 2 of 4 Product: ALL Document #: 90213 Process: Plexus PC‐ 120 Application Instructions Rev.: 1 1) Using too much PC‐120 Only a very thin coat should be left on the metal. You should be able to see a slight “pink” cast as illustrated below. Too Much PC‐120 Correct Amount 2) Not removing oils once primed Wipe the surface with a dry rag The solvents in PC‐120 will clean and “lift” most machining oils, but if the metal isn’t wiped clean of these oils then they will be deposited right back onto the metal surface when the solvent in PC‐120 evaporates! ...
Page 23
INSTRUCTIONS Page 3 of 4 Product: ALL Document #: 90213 Process: Plexus PC‐ 120 Application Instructions Rev.: 1 3) Not abrading corroded surfaces As good as PC‐120 is, it can’t help bonding performance if applied to a surface that is already corroded! Any surface that shows signs of corrosion should be cleaned by sanding or wire brushing to remove any scale or corrosion. After removal of corrosion then treat the surface with PC‐120 as you normally would. 4) Using PC‐120 past it’s shelf life When stored under normal conditions PC‐120 has a shelf life of 12 months in an unopened, original container. PC‐120 bottles are marked with a lot number that is a simple 8 digit code that gives you the date of manufacture. o “807241” for example is 2008, 07 month (July), 24th day (the “1” refers to the first batch of PC‐120 made that day). Use the lot number to make sure the material is still within shelf life. Since it contains isopropyl alcohol, PC‐120 should be tightly capped when not in use to stop evaporation. ...

INSTRUCTIONS Page 4 of 4 Product: ALL Document #: 90213 Process: Plexus PC‐ 120 Application Instructions Rev.: 1 Remember these points! To avoid problems with Plexus PC‐120: Don’t use too much PC‐120. Only a thin layer is needed. Use a clean rag to wipe PC‐120 off before it completely dries to remove surface contaminants it has cleaned. Good quality paper towels are a better choice to minimize introduction of contaminates to surface. Any sign of corrosion already on the surface should be removed by abrading BEFORE priming. Check the lot number for the date to make sure the PC‐120 is less than a year old. Questions Please contact Plexus Technical Service at 1‐800‐851‐6692 or info@itwplexus.com ...
