📦 Part Number: 38097 / 1BX-81450-00
⚡ 18 Pole Magneto Rotor Assembly · EFI Specific · OEM Specification
📍 Installation Position: Engine Magneto Side · Crankshaft End
✅ OEM Quality · 18 Pole Design · Fits Linhai 570cc/650cc EFI Models
This product is a Linhai OEM-spec magneto rotor assembly, part number 38097 / 1BX-81450-00, EFI (Electronic Fuel Injection) version with 18 pole design. The magneto rotor is a core component of the engine's charging and ignition system, mounted on the crankshaft end. As the crankshaft rotates, the rotor generates AC power to supply the vehicle's electrical system and charge the battery. This model is designed for Linhai 570cc/650cc EFI engine platforms.
Over time, the magneto rotor may experience magnet demagnetization, rotor loosening, or keyway damage, leading to insufficient charging output, charging system failure, or ignition problems. Timely replacement of a damaged magneto rotor assembly is essential to ensure proper engine starting and stable electrical system operation.
✅ Genuine Quality Assurance: Manufactured strictly to Linhai original technical standards. Mounting dimensions and dynamic balance are identical to the original part for a perfect replacement.
This magneto rotor assembly (38097 / 1BX-81450-00) fits the following Linhai models:
- Linhai 570 PROMAX E5
- Linhai 570 PROMAX E4
- Linhai 570 PROMAX T3

- 🔄 Direct Replacement: Directly replaces demagnetized, loose, or damaged original magneto rotors.
• Charging system failure, battery frequently loses charge.
• Check engine light illuminated (EFI system power supply异常).
• Headlights are dim or flicker.
• Engine is difficult to start or will not start.
• Unusual noise from the magneto side (loose rotor or detached magnets).
• Inspection reveals demagnetized magnets, cracks, or damaged keyway.
If any of these symptoms occur, replace the magneto rotor assembly promptly.
1. Ensure the vehicle is off and disconnect the negative battery terminal before installation.
2. Remove the magneto side cover, being careful not to damage the gasket.
3. Inspect the crankshaft keyway and woodruff key for damage; replace if necessary.
4. Clean the crankshaft end and rotor inner bore to remove any debris.
5. Align the rotor with the woodruff key and install it onto the crankshaft. Use a special tool to tighten the retaining nut to factory torque specification.
6. Reinstall the magneto side cover and add grease if applicable.
7. Reconnect the battery, start the engine, and verify normal charging voltage.
