Polaris UTV/ATV OEM Stator / Magneto Flywheel - Available at buywitchdoctors.com

Product Specifications: Genuine OEM Polaris Stator / Magneto Flywheel 900W, Part # 4017135.

The electrical system of your off-road machine depends on a delicate dance between magnets and copper. A Polaris UTV/ATV OEM Stator / Magneto Flywheel is the powerhouse behind that system, generating the essential current required to keep your battery charged and your ignition firing.

In the world of high-performance powersports, the flywheel (magneto) does more than just help generate power—it acts as a balanced rotating mass that maintains engine inertia and timing. A Genuine Polaris flywheel is precision-balanced to prevent crankshaft vibration, while the OEM stator features high-grade windings designed to resist the thermal breakdown common in lesser aftermarket units.

Features and Benefits of Genuine Polaris Charging Components

  • Precision Magnetic Alignment: OEM flywheels feature high-strength magnets bonded with industrial-grade adhesives to prevent "shedding" at high RPMs.
  • Superior Thermal Capacity: The stator windings are dipped in specialized high-temp epoxy to prevent shorts-to-ground during extreme engine operation.
  • Crankshaft Protection: Precision-machined tapers ensure a perfect fit on the crankshaft, preventing woodruff key shearing and timing slips.
  • Consistent Wattage: Engineered to provide steady voltage output even at low idle, ensuring your power steering and fuel injection never starve for juice.
  • Direct Plug-and-Play: Features the correct wiring harness lengths and factory connectors for a frustration-free installation.

When to Replace Your Stator and Magneto Flywheel

Charging system failure can be subtle before it becomes catastrophic. Keep an eye out for these warning signs:

  • Intermittent Spark: If your machine sputters or misfires, it may be due to an inconsistent signal from the pulsar coil on the stator.
  • Physical Impact Damage: If a starter bendix fails or a bolt comes loose inside the case, it can physically scar the stator windings or the flywheel magnets.
  • Loss of Charging: If your digital dash shows low voltage (typically under 13V) while the engine is running.
  • Engine Vibration: A chipped or unbalanced flywheel can cause noticeable harmonic vibrations that can damage crankshaft bearings.

Other Popular Stator / Magneto Flywheel Parts and Accessories

  • Flywheel Tool: The specific threaded tool required to pop the magneto off the crank without causing damage.
  • Stator Cover Gaskets: Essential for resealing the engine side-case and preventing oil leaks.
  • Woodruff Keys: The small but mighty steel key that ensures your flywheel stays perfectly timed.
  • Regulators / Rectifiers: The component that takes the AC output from your stator and turns it into usable DC power.
  • Case Bolts: Replacement hardware for the stator cover, often prone to corrosion or stripping.

Frequently Asked Questions (FAQs)

Do I need to replace both the stator and the flywheel?

Not always. If your charging issue is purely electrical (burnt windings), you likely only need a stator. However, if there was a mechanical failure—such as a broken bolt or loose magnet—you must inspect both for physical damage. Even a small scratch on the stator can lead to a short circuit.

Is a special tool required for installation?

To remove the flywheel, you almost certainly need a model-specific flywheel puller. Never use a "jaw-style" puller, as it can warp the flywheel or damage the magnets. Installation typically requires a torque wrench to ensure the center nut is secured to factory specs.

Why did my factory magnets come loose?

Extreme heat cycles and high-vibration environments can eventually break down the adhesives in some older designs. The current Genuine Polaris OEM replacements feature updated bonding processes to prevent this common failure point.
