12.3 HYDRAULIC STEERING (optional)
General points
- Steering is achieved by rotating the engine base. This rotation is done using a hydraulic ram.
- Protect the ram from any risk of impact, scratches or any other type of degradation. No
impurities must ever penetrate the inside of the ram.
Replenishing and bleeding the circuit
- This task must be carried out by a professional engineer: please consult your dealer.
- Use only oil ISO 22.
- The whole of the hydraulic circuit must be kept scrupulously clean: any impurity risks causing
the deterioration of the steering gear.
After each winter, check
that rotating the wheel to starboard turns the boat to starboard;
that the circuit is properly bled;
that there are no leaks in the connections, the pumps, the ram or the flexible hydraulic hoses;
that the pump is filled with oil to the correct level(25 mm of air must be left in the pump : this
space is vital for the hydraulic circuit to work properly, it allows the oil to expand);
that the nuts and screws are fully tightened to the correct torque as shown in the manufacturer's
instructions;
that the hydraulic hoses have not been flattened or deformed.
- Nothing must impede the movement of the
ram: regularly ensure that the ram is able to
function smoothly:
when moving the engine from hard to
port to hard to starboard;
when fully raising the engine.
ADVICE-RECOMMENDATION
- Refer to the manufacturer's instructions for use and maintenance.
- Do not step on the hydraulic ram.
- It is vital periodically to grease the inside of the engine drive-shaft.
