4370 Magneto
The 4370 aircraft magneto is designed for several models of 4-cylinder aircraft engines. This magneto has key features that set it apart from other magnetos:
*No drive gear included*
Magnetos are compatible with many popular aircraft engines, including Lycoming models like the O-320, O-360, and IO-540, as well as Continental engines such as the O-200 and O-300. In general aviation, magnetos are crucial for reliable and efficient ignition, promoting smoother engine starts and stable flight operations. Their durable design also makes them suitable for challenging conditions in military and recreational aircraft, enhancing engine responsiveness and flight safety.
Magnetos support engine performance and can reduce certain maintenance needs by ensuring precise timing and consistent ignition. This precision contributes to engine longevity and reliable operation across various aviation applications.

Magnetos are essential to an aircraft’s ignition system, generating the high-voltage current needed to ignite the fuel-air mixture and power the engine. Because magnetos are self-contained, they don’t rely on external power, making them a highly reliable component.
All types of magnetos—whether standard, Bendix, or PowerUp—need regular maintenance, including an inspection every 500 flight hours. They should also be overhauled at engine servicing intervals or every 12 years, whichever comes first. It’s important to inspect your magneto after any lightning strikes, sudden engine stoppages, or prop strikes. Routine inspections help keep your magneto in top shape and ensure consistent engine performance.
Hartzell Aviation offers new and factory-overhauled Bendix and PowerUp magnetos. Hartzell Aviation uses only FAA-approved parts and adheres strictly to manufacturer specifications for every service.
Hartzell Aviation offers a wide selection of magnetos from trusted makers. We have a variety of options to suit your aircraft's needs, such as Dual Magnetos, Bendix Magnetos, and PowerUp Magnetos.
Bendix Magnetos, made by Teledyne, are unique. They have an unlimited overhaul capability, making them a cost-effective choice. Hartzell Aviation offers a comprehensive exchange program and overhaul services for Bendix Magnetos. Teledyne produced Dual Magnetos until they were discontinued in 2010. Although Teledyne stopped producing Dual Magnetos, Hartzell Aviation has over 20 years of experience servicing them and remains one of the few FAA-certified service stations for dual mag overhauls. While no longer manufactured, we help keep these magnetos in peak condition.
POWERUP, a division of Hartzell Engine Tech, makes PowerUp Magnetos. Their high-quality, reliable ignition systems have earned them a reputation for firing stronger and lasting longer. Hartzell Aviation's decades of engineering experience ensure excellence. Every magneto they produce meets strict industry standards and certifications for top performance.
Each magneto consists of a rotor, core, wire windings, breaker contacts, and a distributor. Hartzell Engine Tech is dedicated to enhancing each of these components for optimal performance. PowerUp Magnetos, for instance, include advancements in several key parts:
Impulse coupling
Breaker assembly
Coils
Block assembly
Capacitor
Distributor
In other words, every component has been meticulously engineered to provide outstanding durability and safety.
Always refer to the manufacturer’s installation manual for specific instructions, torque settings, and timing adjustments. For additional guidance on installing your magneto, visit Hartzell Aviation's Magneto Installation Guide.
Ensure the aircraft is safely secured, and the power source is disconnected. Gather necessary tools, including wrenches, screwdrivers, and a torque wrench. Wear safety goggles and gloves to protect yourself during installation.
Locate the existing magneto and disconnect the electrical connections. Remove the mounting bolts or screws, then carefully extract the old magneto from its position.
Before installing the new magneto, check the mounting area for any debris or damage. Clean the area to ensure a proper fit and inspect the drive coupling for any wear or damage.
Position the Magneto into the mounting location, ensuring alignment with the mounting holes and drive coupling. Secure it with mounting bolts or screws, tightening them to the manufacturer's specified torque settings.
Attach the electrical connections to the magneto terminals. To prevent any electrical faults, ensure that all connections are secure and properly insulated.
Follow the manufacturer’s instructions to set the timing correctly for optimal performance. Use a timing light or other diagnostic tools as required.
Reconnect the power source and perform a functional test of the magneto to ensure it operates correctly. Check for any unusual noises or issues during the test.
Inspect all connections and fastenings to confirm everything is properly secured and functioning as expected.
All magneto overhauls are handled by FAA and EASA-certified repair stations that uphold Hartzell's high standards. You'll get serviceable and new parts that deliver OEM quality at an overhauled price. We offer a complete line of PMA replacement engine parts, overhaul, and 500-hour inspection capabilities.
