2-litre hydraulic pump kit

The Garmin 2-litre hydraulic pump delivers a flow rate of 2.0 litres per minute (0.53 gallons per minute).

This Garmin pump kit is an essential component for marine autopilot systems. Its main features include:

A flow rate of 2.0 litres per minute (0.53 gallons per minute).New ORB hydraulic connections for improved durability.Threaded cable clamps.A design for systems with vented reservoirs.

No, the pump and the check valve use ORB-5 fittings, but these fittings are not included with the pump or the check valve.

The pump requires hydraulic hoses with an internal diameter of -4 [6 mm (1/4 in)] or larger, with a minimum nominal pressure rating of 1000 psi.

Yes, it is recommended to apply a marine corrosion inhibitor spray on the pump body and the manifold after installation to ensure corrosion resistance. Garmin recommends renewing this application once a year to extend the pump's lifespan.

This pump is compatible with the Garmin Reactor™ 40 autopilot system. It is designed exclusively for use with Garmin autopilot systems.

The pump is suitable for boats equipped with hydraulic steering of 10 to 24 cubic inches.

No, this pump must absolutely not be installed with a steering system that has a non-vented reservoir, as this would damage the pump. You must verify that your boat's steering system is equipped with a vented reservoir before installation.

No, the cables connecting the pump to the autopilot’s ECU cannot be extended. The pump must be located within 0.5 meters (19 inches) of the ECU.

The pump must be installed in a dry location, protected from the elements. It is recommended to mount it:

Within 0.5 meters (19 inches) of the autopilot ECU.Within 3 meters (10 feet) of the steering ram to limit the length of hydraulic hoses.If possible, mount the pump horizontally. If not, mount it vertically with the pump head connectors facing upward.

Recommended tools for installation include:

Safety glassesDrill and drill bitsWrenchesWire strippers/cuttersScrewdrivers (Phillips and flat-head)Cable tiesMarine corrosion inhibitor sprayMounting screws (the kit includes some, but you may need different types depending on the surface)Hydraulic system hardware: hydraulic hoses, hydraulic T-fittings, hydraulic shutoff valves, thread sealant (such as LOCTITE 567), hydraulic bleeding equipment, hydraulic fluid.

Yes, but with precautions:

For hydraulic fittings with O-ring (such as ORB and ORFS fittings), do not use thread sealant.
For hydraulic fittings without O-ring, use a liquid thread sealant such as LOCTITE 567.
Never use thread tape (Teflon type) or jointing paste on hydraulic fittings, as debris could damage the system.

To connect the hoses:

Disconnect the necessary hoses from the existing hydraulic system. Add a T-fitting to the port and starboard hoses of the hydraulic system, between the helm station and the steering cylinder. If your boat has no return hose connected to the helm station, add a sufficient hydraulic hose to connect the helm station return fitting to the pump. If a return hose exists, add a T-fitting to this hose. Connect the port and starboard hoses from the T-fittings to the appropriate pump fittings. Connect the return hose (from the helm station or the existing T-fitting) to the central pump fitting. Install the Shadow Drive valve in the port or starboard hydraulic hose, between the helm station and the T-fitting connected to the pump (see the autopilot instructions for details on the Shadow Drive valve).

Yes, it is essential to purge all air from the hydraulic system after installation. A "power purge" process is required to fill the pump and the check valve with hydraulic fluid, followed by the hydraulic system purge instructions provided with your Garmin autopilot system.

Yes, to avoid damaging your boat, the autopilot system must be installed by a qualified marine installer. Specific knowledge of marine steering and electrical systems is required for proper installation.

Install the pump near the steering ram so that the length of the hydraulic hoses connecting the pump to the ram does not exceed 3 meters (10 feet).

Generally, the vent hole is located in the filler cap of the highest helm station. If you are not certain that your steering system is vented, it is recommended to check with the manufacturer of the helm station or the reservoir.

Using sealing tape (such as Teflon tape) or joint compound on any hydraulic fitting in this system may void your warranty. Small debris from these materials can enter the hydraulic system, lodge in valves, and render the autopilot or steering system inoperative.

The two pump cables connect to the ECU ports labeled « DRIVE » and « FEEDBACK ». Some Garmin pump and ECU models use quarter-turn locking connectors, while others use threaded connectors. Spare clamps may be available from your Garmin dealer if the connectors do not match.
