Kit de angrenaje

This N021 gear kit is designed for Raymarine linear and rotary actuators (Type 1 and Type 2).

You should consider replacing the gears if you observe one or more of the following signs on your autopilot:

Excessive or unusual mechanical noise (grinding, clunking) during operation.Significant play in the drive system, resulting in sluggish rudder response.The autopilot motor runs but the ram does not move or moves jerkily.

Installing this kit requires a certain level of technical skill. It involves partially disassembling the autopilot's housing to access the internal mechanism. A person comfortable with small mechanical tasks can perform this operation.

No, kit N021 is not compatible with any ST1000 or ST2000 models. It is designed for mechanical linear and rotary Type 1 and Type 2 actuators. The gear kit for ST1000 and ST2000 pilots is reference Q054.

The N021 kit is a complete solution for overhauling the transmission. It includes all the pinions and gears needed to replace the internal mechanism of your Raymarine linear and rotary actuators.

Yes, it is essential to lubricate the new gears with a high-quality marine grease during installation. This ensures smooth operation, reduces wear, and protects parts from corrosion. The grease is not included in the kit.

Yes, absolutely. The N021 gear kit is an official replacement part manufactured by Raymarine. Using an original part ensures a perfect fit, compliance with tolerances, and restoration of your autopilot’s initial performance.

No, this kit is a specific part for Raymarine and is designed for Raymarine linear and rotary actuators (Type 1 and Type 2). The dimensions and gear design will not match actuators from other brands.

Yes, it is strongly recommended to replace all the gears provided in the kit. Gears wear together. Replacing only one part could lead to premature wear of the new gear and malfunction of the transmission.

To confirm compatibility, you must check the exact model of your autopilot. The model name, such as Type 1 or Type 2 cylinders, is usually printed directly on the device's housing.

Yes. Worn gears create play in the drive, reducing autopilot responsiveness and accuracy. Installing this new kit eliminates play and restores original rudder precision and responsiveness.

Generally, basic tools are sufficient for this operation. Have a set of precision screwdrivers (Phillips and flathead) and potentially small pliers ready. No proprietary Raymarine tools are normally required for this repair.

Kit N021 is not compatible with ST1000+ and ST2000+ models; it is designed for Raymarine linear actuators. ST1000+ and ST2000+ autopilots use a different gear kit (reference Q054).

The main advantage is economic and sustainable. This kit significantly extends the lifespan of your autopilot for a fraction of the cost of a full power unit replacement.

Yes, the most important precaution is to ensure that the autopilot is completely disconnected from any electrical power source before starting to disassemble it. This prevents any risk of short-circuit or accidental activation.

No, this kit is specifically designed for the internal mechanisms of tiller pilots (actuators). It is absolutely not compatible with wheel pilot systems, which use power units and transmissions that are completely different.

No, as a spare part, this kit contains only the gears. It does not come with a paper installation manual. The replacement procedure is detailed in the official service manuals of the relevant autopilots.

Yes, in most cases. If your autopilot’s noise is a mechanical squeak or clack coming from the drive, replacing the worn gears with this new kit should effectively eliminate these noises.

The total weight of the N021 gear kit is approximately 0.2 kg (200 grams).

No, this kit is only for ST1000+ and ST2000+ models. Evolution series autopilots, such as the EV-100, use different internal components and this gear kit is not compatible with them.
