6355 – Slick Impulse Coupled Left Hand Rotation Magneto

Available now on the Airparts.aero Marketplace.

Overview

The Slick by Champion 6355 is a flight-critical, impulse-coupled ignition magneto, an essential component for the dual-ignition systems of six-cylinder Lycoming engines. This is not a standard magneto; it is a high-performance unit from the 6300 series, featuring an integrated mechanical impulse coupling for reliable engine starting. The 6355 is a completely self-contained ignition source, engineered to generate and distribute a powerful, precisely-timed spark without any reliance on the aircraft's electrical system.

Designed for left-hand rotation mounting, this magneto is a cornerstone of general aviation safety and reliability. Its robust construction and time-proven design ensure it can withstand the extreme vibration and temperature of the engine compartment, providing the consistent spark energy required for all phases of flight.

Key Features

• Integrated Impulse Coupling (IC): Features a spring-loaded mechanical impulse coupling on its drive shaft. During the slow rotation of engine start, this mechanism briefly delays the rotation of the magneto's magnet and then rapidly accelerates it. This action generates a single, powerful spark at a retarded timing for a smooth, kickback-free start.

• Self-Contained Ignition Source: Functions as a self-sufficient electrical generator, using the engine's rotation to create the high-voltage spark for ignition. This provides essential redundancy, as the engine will continue to run even in the event of a total aircraft electrical failure.

• High-Energy Output: As a member of the Slick 6300-series, it features a high-efficiency coil and a single-piece rotating magnet design that produces a strong, consistent spark across all engine operating RPMs, ensuring efficient combustion and full power development.

• Durable & Compact Design: Engineered with a lightweight, single-piece aluminum housing that provides superior structural strength and effective radio frequency interference (RFI) shielding. The internal components are designed for a long service life and resistance to moisture intrusion.

• Genuine Champion OEM Quality: As a genuine factory component from the leader in aviation ignition, it guarantees perfect fitment, correct internal timing, and conformance to the stringent material and quality standards required for a flight-critical system.

Why Choose a 6355?

The dual ignition system is a cornerstone of aviation safety, and the integrity of each magneto is paramount. The Slick 6355 is the genuine, factory-certified component designed to provide reliable spark energy for thousands of hours. Using a genuine OEM magneto ensures you are installing a unit with a known history, certified components, and the precise internal timing required for your Lycoming engine. For a system this critical to engine operation, there is no substitute for a genuine factory part.

The impulse coupling on the Slick 6355 is a key piece of mechanical engineering designed to solve the problem of low-speed starts. A magneto's ability to generate a strong spark is directly proportional to its rotational speed. At the slow speed of engine cranking, a standard magneto would produce a very weak spark. The impulse coupling mechanism solves this. It consists of a weighted flyweight and a powerful spring. As the engine turns the magneto drive, the flyweight is held back by the spring, preventing the magneto's rotor from turning. After a few degrees of rotation, the flyweight is released, and the powerful spring snaps the magneto's rotor forward at a very high speed, many times faster than the cranking speed. This rapid rotation generates a single, intense spark. At the same time, this "snap" occurs later in the engine's rotation (retarded timing), which prevents kickback. Once the engine starts and RPM increases past a few hundred RPM, centrifugal force holds the flyweights out, disengaging the spring mechanism, and the magneto operates as a direct-drive unit with normal, advanced timing.

Note: This is a flight-critical engine component. Installation and timing must be performed by a certified A&P mechanic in strict accordance with the current Lycoming maintenance and overhaul manuals. Incorrect timing can lead to poor engine performance, detonation, and catastrophic engine damage.
