The Following is the Installation Procedures of the Complete Gyro-Gale Stabilizer System:
A typical Gyro-Gale Stabilizers installation is very simple and normally takes about 4-7 days for the complete installation and sea trial.
- – Air tank
- – Filter/Lubricator
- – Control unit
- – Fin unit
- – Bridge control
- – Compressor
- – Heat exchanger
- – Air dryer
- – Inter connecting tubing end fittings
A. Air Tank Installation
The air tank is best installed over head. In this case, the tank is bolted to a wooden platform and the assembly is then installed over head, preferably in the engine room.
B. Filter/Lubricator Unit Installation
Install the Filter/Lubricator Unit on any vertical partition or bulkhead in the engine room. A clearance below the bottom of the unit must be at least 8in to allow disassembly. The unit should be located in an easily accessible position to check the mineral oil level and top it as required.
C. Control Unit Installation
Install the control unit, preferable as high as possible within the engine room, on a transverse bulkhead or partition so that the unit is facing either forward or aft. The position of the control unit should be selected as close as possible to the vessel center line so that the length of the tubing running to the fins are short and almost of equal length.
D. Electronic Gyro Installation
The Electronic Gyro?s Electronic Box must be mounted 100% horizontally and 100% vertically to ensure proper stabilization. The Electronic Box will come from the GyroGale factory with a Mounting Board. Fasten the Mounting Board to the helm using 4 wood screws. While mounting the Electronic Box, be cautions that none of the wires are squeezed, cut, tugged or damaged what so ever. Once the Mounting Board is secured and wires are cleared inside the helm through panel board, install Bezel. Bezel will require 2 wood screws, one on each side. Pass these 2 wood screws through bezel, panel board and into mounting board. This will properly secure bezel and mounting board while sandwiching panel board.
E. Fins & Driving Mechanism Installation
The installation of the Fins and Driving Mechanisms requires that the vessel be hauled out. The following is a step by step for the complete installation of the Fins:
- 1. Locate convenient positions for the fins within the middle third of the water line. If you are using two or more fins on each side of the vessel, try to locate them as far as you can from one another so that the cavitation of one fin does not reach the other fin. This will depend on the speed of the vessel, and the length of the middle third of the water line.
- 2. Using a wooden template of the Inner plate, position the template against the outside of the hull at the desired location. The shaft of the fin should be almost perpendicular to the hull. The tip of the shaft at this position must be at least 2ft 11 within a vertical line from the widest point of the hull as well as the keel line. This arrangement insures that the fins will be protected when the vessel is being docked or hauled
- 3. Using the template, drill holes 1/2in for the holding bolts (three) and the hole for the center shaft 2 1/8in diameter.
- 4. Assemble the outer plate on the hull. Note that the three holding bolts should be of the same length as these will be used to align the inner plate.
- 5. Assemble the inner plate and use the length of the holding bolts to insure that the inner and outer plates are parallel. Tighten the nuts or the holding bolts and be sure that the drive shoe is moving freely and without any binding.
- 6. Mark the excess length of the inner tube, (1 3/4in) above the drive shoe. Disassemble the unit and cut off the excess length.
- 7. Using a bedding compound (5200) on the inner and outer plates, repeat step #4 & #5. Also use the bedding compound around the holding bolts. Make sure the outer plate is completely sealed against the hull.
** The fins must be free to move easily by hand from one side to the other. Any tightness of the fin movement is due to misalignment and must be corrected before the vessel is back in the water.
F. Tab-Fin Installation
The Outer Plate must be fastened to the hull with 5200 bedding compound as well as three ?? holding bolts. Once the 5200 is cured, then the Tab-Fin is to be installed on the Outer Shaft. Apply Anti-Seize lubricant(must meet MIL-SPEC-A907E) between all moving parts prior to installing fin on the shaft. Anti-Seize Lubricant must be applied as follows:
- – Lubricate the outer rim of Hex Sleeves on all Lower and Upper Drives.
- – Lubricate 2″ at the top and bottom of Outer Tube
- – Lubricate inside the bushings of the fins and at the area where the fin seal will slide alone and will be embedded at 3″ from Outer Plate
- – After installing Fin and installing Spacer and Snap Ring, lubricate inside of Outer Tube and Inner Tube where the O-Ring Seals are located.
- – Lubricate the Tab Slot and Pivot Hinges.
G. Bridge Control Installation
The bridge control can be mounted at a point of preference on the bridge control panel. Drill 2 holes 2 1/8in for the gauges & 1in for center switch.
H. Compressor on Engine Installation
1. GM Engines
- – Remove drive take-off cover from back of engine (propeller side).
- – Insert drive plate and fasten with 4- SAE 3/8in – 1 1/2in long bolts
- – Insert drive hub on compressor shaft and secure with locking nut.
- – Insert drive coupling between engine and compressor.
- – Assemble compressor on engine.
- – Install the air cleaners (breather) on both compressors.
- – Install the governor on either compressor.
2. 3208 Cat Engine
Use belt drive compressor which may be mounted:
- – On top of the engine by relocating the engine’s heat exchanger.
- – On side of engine attached to one of the forward engine support bracket (brackets are available by Gyro-Gale).
3. 3609 Cat Engine
- – Power take off with compressor male spline inserted into engine’s female spline.
4. 120 & Ford Lehman Engine
- – Belt driven from front engine’s pulley. A compressor bracket is generally mounted onto the engine forward support (bracket available by Gyro-Gale).
- – At this stage the two compressors are mounted on the engines and ready to be connected to the rest of the system.
I. Heat Exchanger Installation
The heat exchangers are installed in line with the raw water system of the main engines. The heat exchangers should be installed as close as possible to the compressors to minimize the length of the hoses running between the compressors and the heat exchangers, thus, exposed to high temperature.
J. Air Dryer Installation
The air dryer is installed on any vertical partition or bulkhead. The drainage from the dryer (1″ line) runs into the engine’s muffler or generator’s muffler.
