Detailed description

The clutch rotor assembly N007 is an original Raymarine spare part, designed for the maintenance and repair of autopilot drive units. This component is essential for the proper functioning of the autopilot system's engagement and disengagement mechanism, ensuring a smooth transition between autopilot mode and manual steering.

Function and technology of the Raymarine clutch

The clutch in a Raymarine drive unit is an electromagnetic or electromechanical mechanism. When engaged, it connects the autopilot motor to the vessel's steering system. In standby or manual mode, it disengages to allow free movement without resistance from the pilot. This rotor assembly is a central element of this mechanism, ensuring reliable and precise locking and unlocking.

Positioning and compatibility

Raymarine offers a complete range of parts for its various drive units (mechanical linear, hydraulic linear, rotary). Unlike more comprehensive maintenance kits such as the clutch kit for ST4000 MK2 (reference A18084) which includes rollers and cams, product N007 is a specific clutch rotor assembly. It is imperative to verify the compatibility of this part with the exact model of your Raymarine drive unit before installation.

Frequently Asked Questions

Need help? Contact us

What autopilot model is this clutch compatible with?

This clutch is specifically designed to be compatible with the Raymarine Type 1 and Raymarine Type 2 rotary drive units. It is not compatible with other models or types of drive units.

What are the signs that indicate I need to replace my autopilot clutch?

Replacement is generally needed if you observe one or more of the following symptoms:

The autopilot 'slips' and cannot maintain course.Engagement or disengagement of the pilot is noisy or does not occur correctly.The autopilot no longer engages at all, even if the electronics appear to be functioning.You feel abnormal resistance on the helm when the pilot is disengaged.

Is this an official Raymarine branded spare part?

Yes, the clutch rotor assy N007 is an original spare part manufactured by Raymarine. Using an official part guarantees perfect compatibility and optimal performance for your equipment.

How does this electromagnetic clutch work?

The operation is simple:

When you activate the autopilot, electrical voltage is sent to the clutch. This electromagnet locks, connecting the motor to the steering system.When you deactivate the pilot, the current is cut off. The clutch releases, offering no resistance and allowing you to steer manually.

Is the installation of this part complicated?

Replacing the clutch requires basic mechanical skills and some care. Part of the drive unit needs to be disassembled to access the part. If you are not comfortable with this type of intervention, it is recommended to use a qualified technician.

Are special tools required for replacement?

No highly specialized tools are generally required. However, you will need a set of basic mechanical tools, such as wrenches, screwdrivers, and potentially circlip pliers, depending on the exact assembly of your drive unit.

Is this clutch compatible with a ram (linear) autopilot?

No, absolutely not. This clutch is designed for a rotary drive unit, which drives the helm via a chain and sprocket. Linear ram autopilots have a completely different clutch system.

What happens if I continue to navigate with a faulty clutch?

Continuing to use a faulty clutch means you cannot rely on your autopilot. The steering function will either be inoperative or unreliable, which can pose safety issues, especially with a reduced crew or during long passages.

Should I cut the electrical power to the pilot before starting the installation?

Yes, this is an essential precaution. Before working on the power unit, you must cut the power to the autopilot at the circuit breaker or electrical panel to avoid any risk of short circuit or accidental activation of the motor.

Are there any electrical connections to redo during assembly?

Yes, the clutch is an electromagnet. It is powered by two electrical wires. When replacing it, you will need to disconnect the wires from the old clutch and reconnect those of the new one.

Why is this part called "clutch rotor assy"?

The designation "clutch rotor assy" (assembly) means that it is an assembled unit that includes both the clutch (the electromagnetic part) and the rotor (the moving part that transmits motion). You receive the complete part for replacement.
