Operating a small vessel inevitably leads to wear and tear of the control mechanisms, and one of the first symptoms of problems is a backlash or jamming of the rudder. The question of how to remove the steering wheel on the boat often arises before owners who notice “coat” control or extraneous sounds when turning the steering wheel. bearing-assemblyReplace worn-out sleeves or completely change the gearbox, returning the boat to its former handling.
The removal process does not require complex tools, but requires an understanding of the design of your control system, whether it is a mechanical cable, hydraulics or a powered tube. Ignoring the creaks and backlashes can lead to a critical situation on the water, where maneuverability becomes a matter of safety. In this article, we will discuss in detail the algorithms of actions for different types of designs.
It is important to understand that before starting work, you need to ensure the stable position of the vessel. If you are working on a trailer, make sure that the boat is securely fixed and the transom board is free to access. Removing the steering wheel often requires simultaneous access to the transom and the inside of the cockpit, so make room for work ahead of time..
Tool preparation and malfunction diagnosis
Before starting the dismantling, you need to clearly define the nature of the malfunction. If the steering wheel is just tightly rotated, perhaps the problem lies in the lack of lubrication or dirt getting into the car. bearing-holdIn the case where there is a tangible backlash (free running of the steering wheel without the reaction of the boat), most likely, the bushings were worn or the geared crown of the gearbox collapsed.
To work properly, you need a basic set of tools that every boat owner should have, and the lack of keys can lead to the slicing of the bolt faces, which will make the process much more complicated.
- 🛠️ A set of wrenches and heads (the main tool for unscrewing the fastener)
- 🔨 Hammer and chisel (for neat knocking out studs and axles)
- 🧴 Penetrating lubricant WD-40 or analogues (for processing acidic compounds)
- 🧼 Lace and brake cleaner (to remove old lubricant and dirt)
Remember to degrease the surface before work begins so that dirt does not get inside the mechanism during dismantling. It is also recommended to photograph the initial position of all rods and mounts so that there are no problems with adjustment during assembly.
Dismantling of the tiller control on the outboard motor
The most common replacement issue is with the tiller motors, where wear is most likely due to direct hand-over of the operator, and before removing the steering wheel on the outboard motor, you need to disconnect the thrust of the gas if it is integrated into the handle of the tiller so as not to damage the cable.
The process begins with the removal of the decorative lid of the hummel, which is usually attached to several screws or plastic latches. Be careful, the plastic on the old engines becomes brittle and can crack if you handle it sloppy. turn-piece and a locking bolt.
The central bolt holding the tiller often has a secret head and can be sour. Treat it abundantly with penetrating lubricant and let it stand for 10-15 minutes. If the bolt fails, do not use excessive force immediately so as not to break the thread in the aluminum body of the motor.
⚠️ Warning: Before unscrewing the central bolt, make sure the rummel is fixed in a horizontal position. A sharp break of the thread can cause a heavy metal lever to fall on the leg or damage to the transom of the boat.
Once the bolt is unscrewed, the romple may not be removed immediately because of the corrosion of the slats joint. Light hammer tapping through a wooden pad or using a special detacher will help to move it from its place. Don't try to loosen it excessively so as not to damage the oss.
When installing a new tiller, be sure to lubricate the slate connection with lithium lubricant so that the next time the dismantling goes without problems.
Removal of steering: gearbox and cable
If you have a steering system on your boat, the process is complicated by the gearbox and the cable gear. To remove the steering wheel, first of all, you need to dismantle the steering wheel itself. To do this, remove the decorative cap in the center, unscrew the nut and carefully pull the steering wheel off the slits.
Then there's the step of disconnecting the cable from the gearbox. Steering Cable They're under constant tension, and before you remove the fastening bolts on the gearbox, you need to loosen the tension or lock the cable so that it doesn't go inside the casing or the transom.
- 🔩 Unscrew the gearbox mount bolts to the transom board (usually 4 bolts on the back).
- 🔌 Disconnect the electric connectors if the gearbox has a steering position sensor.
- 🧵 Carefully pull the cable from the gearbox body, monitoring the integrity of the braid.
When removing the gearbox, look at the condition of the transom seats. If there was water, you might need fiberglass repair or metal digestion. Installing a new gearbox requires careful sealing of the holes.
☑️ Check before removing the gearbox
Replacement of bearings and steering column bushings
Often, complete replacement of the unit is not required, and it is enough to change the worn elements. In the design of the steering column, slip bearings (sleeves) or ball bearings are most often used, and their wear leads to the steering wheel cruising up and down or having a side backlash.
To replace, you need to disassemble the column completely, taking out the shaft. Old sleeves of fluoroplastic or bronze can be pressed tightly. Use a mandrel of the appropriate diameter to knock them out without damaging the landing hole in the case.
New bearings must be made of materials that are resistant to seawater and aggressive environments. Stainless steel products or specialized polymer composites are ideal. sea-lubricant, which is not washed away by water.
| Type of wear and tear | A symptom. | Decision | Detail required |
|---|---|---|---|
| Wear of bushings | Vertical backlash shaft | Replacement of bushings | Fluoroplastic bushings |
| Corrosion of the shaft | Snatch, jerk. | Grinding or replacement | Helmsman's shaft (stainless steel) |
| Breaking teeth | Total failure of management | Replacement of gearbox | Steering gearbox |
| Lubrication drying | Tight move, creaking | Cleaning and lubrication | Lithium Marine Lubricant |
After assembly, check the ease of travel. The steering wheel should be rotated by one hand (for the steering wheel) or with moderate effort (for the rumpell) without jamming in extreme positions.
Where can I find the bushing plans?
If the original parts are not produced, the worn sleeve can be used as a sample for a turner, the material can be korolon or bronze.
Features of removing the steering wheel on different types of boats
The design of the steering wheel mounting can vary significantly depending on the type of vessel. PVC inflatable boats often use removable transom boards with integrated mounting, where the steering wheel is removed along with the board or detached through quick-removal fittings.
On metal boats (Kazanka, Ob, Wind), steering columns are often welded or glued directly to the hull. Here, removing the steering wheel may require working with the inner lining of the cockpit. Access to the nuts of the mounting can be closed with a gas tank or seats.
In the case of fiberglass boats, the situation is even more complicated: access to the back of the transom is often limited, sometimes you have to make a process hatch in the bulkhead to replace the steering gearbox or dismantle the engine if it is installed inside the hull.
⚠️ Warning: On metal boats, the old steering column mount bolts can be corrosion-snatched. Use heating (carefully not to damage the paint) or drilling, but don't break the fasteners, otherwise it will take hours to recover the wreckage.
Always consider transom material when choosing a fastener for remounting. Aluminum and fiberglass require different types of sealants and bolts to avoid electrochemical corrosion.
The main difficulty in removing the steering wheel on old boats is access to the fasteners. assess in advance whether you need to dismantle the adjacent equipment (gasoline tanks, seats, skin).
Assembly, adjustment and testing of the system
Once the necessary components are successfully dismantled and replaced, the assembly phase begins. It is critical to assemble all the components correctly, observing the puff moments. Tight bearings will lead to rapid wear and tight running, and understretched ones to the emergence of backlash.
Be sure to use new splints, locking washers and a carving fixator where it is provided by the design. Vibration on the water can unwind even well-tightened nuts if they are not fixed.
- 🌊 Check the tightness of all passages through the transom (especially for cable systems).
- 🔄 Make sure that the steering wheel is symmetrical in both directions (from side to side).
- 🛑 Check the operation of the locking mechanism (steering position fixer).
The final test is best done on land, by turning the steering wheel from the far left to the far right several times, and the mechanism should work smoothly, without creaking or dips, only after that you can lower the boat into the water for a test swim.
Do I need to change the cable when replacing the gearbox?
It is recommended to change the cable with the gearbox if the system mileage is high. The old cable may have internal braid breaks or corrosion, which will lead to a jam in a new, perfectly working gearbox.
How do you lubricate the steering gear?
Use only specialized lithium or silicone lubricants labeled "Marine" -- conventional car lubricants are quickly washed out by water and lose their properties at low temperatures.
How often should the steering be maintained?
Preventive maintenance (cleaning and lubrication) is recommended at least once a season, preferably before navigation. After each release into salt water, it is desirable to rinse the mechanism with fresh water.
