This driven gear is a high-quality OEM replacement for CFMoto, directly replacing part numbers 0180-091001-00001 and the older CF188-091001. It is also compatible with Linhai part numbers 35260 and 1BE-15517-00. This gear is mounted on the overrunning clutch and meshes with the starter motor's pinion gear to transmit starting torque to the engine flywheel.

The driven gear is a vital component of the starting system. Over time, the gear teeth can wear, pit, or even break, causing starting noise, poor engagement, or a no-start condition. It is often replaced together with the overrunning clutch as an assembly.

• Direct OEM Replacement: Perfectly matches CFMoto part numbers 0180-091001-00001 and CF188-091001, ensuring precise fitment.
• High-Strength Alloy Steel: Manufactured from premium alloy steel for excellent impact and fatigue resistance.
• Precision-Machined Teeth: Accurate gear profile ensures smooth engagement with the starter pinion and efficient torque transfer.
• Hardened Tooth Surface: Teeth are induction-hardened for high surface hardness and excellent wear resistance, extending service life.
• Critical Starting Component: Ensures reliable transmission of starting torque for smooth engine starts.

✅ Importance of Driven Gear Replacement: The driven gear constantly meshes with the starter pinion, making its teeth susceptible to wear and pitting. Severe wear can cause starting noise, poor engagement, or failure to start. If the starter motor runs but the engine cranks slowly, noisily, or not at all, inspect this gear. It is often recommended to replace it together with the overrunning clutch.

⚠️ Installation Tip: This gear is mounted on the overrunning clutch. Ensure proper fitment between the gear and the clutch during installation. It is also advisable to inspect the starter motor pinion gear for wear and replace it if necessary.
